      This study examines the expression of HDAC3 within DC compartment. Taking advantage of tamoxifen inducible ERT2-cre mouse model they observe the dependency of pDCs but not cDCs on HDAC3. The requirement of this histone modifier appears to occur during development around the CLP stage. Tamoxifen treated mice lack almost all pDC besides lymphoid progenitors. RNA seq studies identify multiple DC specific target genes within the remaining pDC - using Cut and Tag technology they validate some of the identified targets of HDAC3. Taken together, this study shows the requirement of HDAC3 on pDC but not cDC, congruent with the recent findings of a lymphoid origin of pDC.

      These authors present a powerful tool to unbiasedly identify lysosome-associated proteins in C. elegans, and they provide a compelling, in-depth assessment of how this method can be used to understand longevity pathways and identify novel proteins. Understanding lysosomal differences in specific tissues or in response to different longevity conditions are exciting as it provides new insight into how organelles could control specific homeostasis responses. This valuable tool and proteomics datasets also represent a great resource for the C. elegans community and should pry open new studies on the regulation and role of the lysosome at the organismal level.

      Irises on top of being a popular and beautiful ornamental plant, have wider commercial interest due to the many interesting secondary metabolites present in their rhizomes that have value to the fragrance and pharmaceutical industries. Many of these have large and difficult to assemble genomes, and to fill that gap the Dalmatian Iris (Iris pallida Lam.) is sequenced here. Using PacBio long-read sequencing and bionano optical mapping to produce a giant 10Gbp assembly with a scaffold N50 of 14.34 Mbp. The authors didn’t manage to handle the haplotigs separately or to study the ploidy, but as all of the data is available for reuse others can explore these questions further. This reference genome should also allow researchers to study the biosynthesis of these secondary metabolites in much greater detail, opening new avenues of investigation for drug discovery and fragrance formulations.

    1. eLife assessment

      This important study provides convincing data in support of the conclusion that weak but not strong fear memories are more easily modified using behavioural and pharmacological approaches potentially as a result of differential connectivity with the amygdala showing greater connectivity through the brain in weak compared to strong memories. The scope of the paper would be strengthened if both sexes were examined and more varied definitions of weak vs. strong memories were used. This paper is of interest to behavioural and neuroscience researchers studying learning, memory, and/or neural networks.

      The manuscript offers important findings on the potential influence of maternally derived extracellular vesicles on embryo metabolism. However, while the content is convincing, the title appears to overstate the study's conclusions due to its speculative nature on the DNA transmission and embryo bioenergetics connection. A more measured title would better represent the evidence presented.

      Birman et al. present a valuable software interface, Pinpoint, for planning anatomically precise insertions of rigid instruments (e.g., electrodes, injection needles/pipettes, fibre optic implants) into the mouse brain. The authors provide compelling evidence of the potential of this software since, it: (1) incorporates the geometrical constraints of the rig and instruments; (2) interfaces with popular manipulator systems and data acquisition software; (3) runs on any browser; and (4) allows for easy collaboration among users. Despite these exciting features, quantification of the gains in experimental efficiency and accuracy derived from Pinpoint is needed.

    1. eLife assessment

      This important paper examining the relationship between ventral tegmental area dopamine activity and the activity of lateral hypothalamic orexin neurons in the context of reward learning. However, whereas the photometry imaging data are compelling, the functional links to behavior are incomplete since the necessity for dopamine-mediated orexin neuron recruitment in the hypothalamus to the observed behavioral effects is not unambiguously demonstrated. The study expands current notions of dopaminergic function and will be of broad general interest to those interested in reward related behaviors, learning, dopamine, lateral hypothalamus, or orexin function.

    1. eLife assessment

      This study presents valuable findings on the relationship between prediction error and brain activation in response to unexpected omissions of painful electric shock. The strengths are the research question posed, as it has remained unresolved if prediction errors in the context of biologically aversive outcomes resemble reward-based prediction errors. The evidence is incomplete due to the task design, which induces a disconnect between verbal instructions and experiential learning, and the lack of analyses accounting for learning and updating of expectations, which are crucial to neural prediction error signaling. The work will be of interest to cognitive neuroscientists and psychologists studying appetitive and aversive learning.

    1. eLife assessment

      This valuable study introduces an innovative method for measuring interocular suppression depth, which implicates mechanisms underlying subconscious visual processing. The evidence supporting the effectiveness of this method would be solid after successfully addressing concerns raised by the reviewers. The novel method will be of interest not only to cognitive psychologists and neuroscientists who study sensation and perception but also to philosophers who work on theories of consciousness.

    1. eLife assessment

      This paper studies how amacrine cells influence retinal output signals. The approach taken is unusually direct and has the potential to make important contributions to our understanding of amacrine cells, and more generally interneurons, to circuit function. The contributions of the work described, however, are limited by several key concerns. Specifically, the results rely heavily on assumptions made about how signals traverse the retina; as a result, the evidence for adequate separation of signals contributed by the amacrine cells and those from other parallel retinal pathways is incomplete.

    1. eLife assessment

      This important study presented a series of results to uncover the role of C-terminal half of the Syx1 SNARE domain. The evidence supporting the conclusions is solid, although more mechanisms in the study would have strengthened the work. The paper will be of interest to biophysicists and neurobiologists.

    1. eLife assessment

      This study used fMRI in an animal that simulates a type of epilepsy to ask if the responsiveness of the brain was altered during a seizure. The results suggest that the brain responsiveness is reduced during the seizures. The significance of the findings is useful and the strength of the evidence is incomplete but could be strengthened after additional experiments.

      This report details convincing evidence that experience with multilingualism in general, and with larger phonological inventories specifically, is related to differences in the structure of the transverse temporal gyri. The project is notable for using a relatively large sample, and confirming the primary finding in a smaller sample. Although results are sometimes slightly counterintuitive (both increases and decreases in cortical thickness are related to experience with multilingualism), the important findings strongly point to experience-dependent plasticity related to language experience as a driver of neuroanatomy of the auditory cortex.

      This manuscript describes useful data on the mechanisms underlying the activation of the receptor tyrosine kinase FGFR1 and stimulation of intracellular signaling pathways in response to FGF4, FGF8, or FGF9 binding to the extracellular domain of FGFR1. Solid evidence for quantitative differences in the downstream responses induced by the three ligands is presented. This manuscript will be of interest to biochemists and cell biologists working on receptor tyrosine kinases and general cell signalling across membranes.

      This study presents valuable findings on the impact of C-natriuretic peptide (CNP) treatment in vivo on the fertility of aged mice. Solid data indicate CNP induces the cAMP-PKA pathway, causing reduced recruitment of Parkin protein to mitochondria in oocytes, resulting in reduced mitophagy, which may be significant for increased mitochondrial bioenergetics and improved cytoplasmic and nuclear maturation. The authors make additional claims regarding the mechanisms by which CNP impacts oocyte quality in vivo for which the evidence is inconclusive. This work will be of interest to reproductive biologists and clinical infertility specialists.

      This important study will provide evidence about a novel screen-triage-treat strategy for cervical cancer prevention. The strategy would contribute to improving access to cervical cancer prevention to vulnerable women with low access to health care, and, therefore, at the highest risk of cervical cancer. However, the current protocol description is currently incomplete and missing key information for clarity and reproducibility.

    1. eLife assessment

      This is an important study that uses chromatin accessibility as a measure to determine the impact of neuronal activity on the state of chromatin regulatory elements in striatal neurons. The authors provide convincing evidence of how Pdyn gene expression is highly dependent on a distal regulatory genomic region both at basal and upon neuronal activation in this particular system, a mechanism conserved as well in human neuronal cells. Although the basic idea of accessibility changes have been studied before, this paper ties previous findings all together in one place and uses the analysis to identify a functionally relevant and conserved enhancer for the prodynorphin gene with potential relevance for neuropsychiatric disorders beyond basic cellular neuroscience. The study will be of interest to neuroscientists studying the striatum, neuronal plasticity, or related neuropsychiatric disorders.

    1. eLife assessment

      This study is useful in identifying several gain-of-function division variants that can suppress the elongated cell division defect phenotype caused by the depletion of Age1 (or AdvA as named in other studies), a known essential cell division protein in Acinetobacter baumannii. However, characterizations of AdvA's localization patterns and its interactions with other divisome proteins are incomplete due to the lack of (1) functional characterizations of fluorescent fusion proteins, (2) considerations for membrane protein topology in the bacterial two hybrid assay, and (3) lack of high-quality fluorescence images for the co-localization studies. The results do not yet support the major claim that Age1 plays a critical role in the assembly of the A. baumannii divisome.

      This important study presents an exhaustive structural analysis of a complete tripartite HipBST toxin-antitoxin system of the Enteropathogenic E. coli O127:H6, which represents a fascinating variation on the well-studied HipAB toxin-antitoxin system. The convincing data show that major features of the canonical HipAB system have been rerouted to form the tripartite HipBST, revealing a new mode of inhibition of a toxin kinase.

    1. eLife assessment

      This important study demonstrates use of the mammalian Musashi-1 (MSI-1) RNA-binding protein as a tool for regulating gene expression in Escherichia coli. The system could also be used for mechanistic studies of MSI-1. The authors provide solid evidence that MSI-1 functions as an effective repressor that acts post-transcriptionally. The impact of MSI-1 as a synthetic biology tool could be strengthened by expanding the analysis of MSI-1's allosteric regulation by oleic acid. The work will be of interest to synthetic biologists.

    1. eLife assessment

      This is an important study that develops a new model of the way muscle responds to perturbations, synthesizing models of how it responds to small and large perturbations, both of which are important to predict how muscles function for stability but also how they can be injured. The evidence presented to support the model is solid, but the work is incomplete as it is particularly lacking a more detailed analysis of the trade-offs associated with using the model to simulate different types of preparations, especially single muscle fibers compared to whole muscles or whole muscles and tendons. With a clearer discussion of the limitations of the model and the situations in which it is best applied, the work will be of interest to those developing realistic models of the stability and control of movement in humans or other animals.

      This important study combines molecular genetics and target validation to discover genes involved in obesity and determine their role. The reviewers unanimously agree that the work is important in terms of significance: it has conceptual and practical implications beyond metabolism, including embryonic and placental development. They also considered that the strength of evidence is convincing from the use of their forward genetic screen in mice. In some instances, reviewers considered that the work was not more than solid because although the methods, data, and analyses broadly support the claims, minor weaknesses emerge on which they suggest improvements for you to consider and selectively address.

    1. eLife assessment

      This work reports a valuable finding on glucocorticoid signaling in male and female germ cells in mice, pointing out sexual dimorphism in transcriptomic responsiveness. While the evidence supporting the claims is generally solid, additional assessments would be required to fully confirm an inert GR signaling despite the presence of GR in the female germline and GR-mediated alternative splicing in response to dexamethasone treatment in the male germline. The work may interest basic researchers and physician-scientists working on reproduction and stress-related disease conditions.

    1. eLife assessment

      This important study enhances our understanding of the effects of landscape context on grassland plant diversity and biomass. Notably, the authors use a well-designed field sampling method to separate the effects of habitat loss and fragmentation per se. Most of the data and analyses provide solid support for the findings that habitat loss weakens the positive relationship between grassland plant richness and biomass.

    1. eLife assessment

      This study provides useful insights into the subcellular localization, interaction with integrins, and function of the cell surface receptor Piezo1 in migrating human T-cells. The data collected is convincing but incomplete. Therefore the idea that Piezo1 is critically sensing mechano-physical cues during T-cell migration is not well supported by direct experimental evidence.

    1. eLife assessment

      This study provides valuable insight into the role of miR-199a/b-5p in cartilage formation. The evidence supporting the significance of the identified miRNA and its target mRNA transcripts is convincing, however further experiments and a broader contextual analysis are warranted to draw a more robust conclusion. This paper will likely primarily benefit scientists focused on diseases related to this biological process, such as osteoarthritis. Furthermore, researchers interested in miRNAs as a broader subject may find the computational model development methodology useful.

The work will be of interest to cell biologists, neuroscientists and clinical neurologists.

    1. eLife assessment

      This important study reports a novel measurement for the chemotactic response to potassium by Escherichia coli. The authors convincingly demonstrate that these bacteria exhibit an attractant response to potassium and connect this to changes in intracellular pH level. However, some experimental results are incomplete, with additional controls/alternate measurements required to support the conclusions. The work will be of interest to those studying bacterial signalling and response to environmental cues.

    1. eLife assessment

      This valuable study addresses the temporal patterning of a specific Drosophila CNS neuroblast lineage, focusing on its larval development. The work is solid: the authors find that a temporal cascade, involving the Imp and Syp genes, changes the fate of one daughter cell/branch from glioblast (GB) to programmed cell death (PCD), as well as gates the decommissioning of the NB at the end of neurogenesis.

    1. eLife assessment

      This fundamental work substantially advances our understanding of cell migration, especially in that of cranial neural crest. The evidence supporting the conclusion is compelling, with rigorous biochemical assays for materials used and with intensive genetic interventions. The work will be of broad interest to developmental biologists and cell biologists.

    1. eLife assessment

      This manuscript examines shared and divergent mechanisms of disruptions of five different mTOR pathway genes on embryonic mouse brain neuronal development. The significance of the manuscript is important, because it bridges several different genetic causes of focal malformations of cortical development. The strength of evidence is compelling, relying on both gain and loss of function, demonstrating differential impact on excitatory synaptic activity, conferring gene-specific mechanisms of hyperexcitability. The results have both theoretical and practical implications for the field of developmental neurobiology and clinical epilepsy.

    1. eLife assessment

      The present study offers valuable insights into the emergence of oscillations in neural networks. It underscores the importance of achieving a delicate balance between excitatory and inhibitory links and deals with the topological conditions for oscillations providing incomplete evidence for the observed features.

    1. eLife assessment

      The authors report that an interaction between the sodium-activated potassium channel Slack and Nav1.6 sensitizes Slack to inhibition by quinidine. This is an important finding because it contributes to our understanding of how the antiseizure drug quinidine affects epilepsy syndromes arising from mutations in the Slack-encoding gene KCNT1. The results are largely compelling, although additional data would strengthen the claims of a direct channel-channel interaction in neuronal cell membranes.

    1. eLife assessment

      This important study demonstrates that disrupting a common protein-folding system restores sensitivity to antibiotics in drug-resistant clinical bacterial pathogens. Although some additional controls would be welcome, the work is overall convincing in showing that targeting protein folding can be used to combat multi-drug resistant pathogens, both by potentiating the efficacy of existing drugs and by therapeutic use of small-molecule inhibitors. This study is significant and timely as it furnishes a new strategy that is relevant to microbiologists and clinicians interested in combating antimicrobial resistance.

    1. eLife assessment

      This study develops an important method for dissecting out two overlapping cell signaling pathways, phosphoinositide signaling and membrane protein trafficking. The combination of two state-of-the-art techniques provides compelling evidence for a reciprocal influence between an enzyme and a channel. The work will be of interest to the broader cell biology, biophysics and biochemistry communities.

    1. eLife assessment

      This study presents a valuable finding on the key factors of T cell responses associated with durable antibody responses following COVID-19 mRNA vaccinations. The data were collected with solid methods and approaches, but the interpretation of the conclusion may be biased due to the experimental design. If confirmed, it may have a great impact on future COVID-19 vaccine design. However, some of the evidence supporting the claims of the authors is incomplete with a small size of the samples, unproven validity of using the expanded T cells, and over-interpretation on the sequence homology data.

    1. eLife assessment

      This paper is important because of its integration of movement and contextual information to control a virtual arm for individuals with upper-limb differences. The provided evidence convincingly demonstrates the approach's feasibility for manipulating a single object shape in different orientations within a virtual environment. However, additional improvements are needed for this proof-of-concept neuro-model to fulfil practical requirements.

    1. eLife assessment

      This study presents a new and valuable theoretical account of spatial representational drift in the hippocampus.

    1. eLife assessment

      This is a valuable study of the molecular basis of summer-to-winter transition in the pear psyllid pest, Cacopsylla chinensis (hemiptera). The molecular and organismal experiments using current methodologies to evaluate the cold responsiveness of the target proteins are mostly convincing, but the structural and phylogenetic analyses remain inconclusive. The results of this study will be of interest to entomologists.

    1. eLife assessment

      Linker histone variants are prevalent throughout the eukaryotic lineage, but their specific roles in shaping chromatin structure are not well elucidated as antibodies did not exist to study these variant H1s. This useful study provides for a solid advance by addressing where these variants are localized in the human nucleus, finding specific enrichment that might shed light on their function. The work could benefit from a deeper functional dissection and some additional controls to independently validate the localization patterns observed. The findings will be of interest for the chromatin field.

    1. eLife assessment

      This valuable methodological development, which combines light (confocal) microscopy with high-resolution scanning EM and EM tomography, expands the level of structural detail accessible to large-volume EM studies and thus represents an approach to integrate the analyses of cellular and sub-cellular levels in biological samples. The data provide a convincing proof-of-principle. They will be of particular value to cell biologists interested in the in-depth interpretation of high-resolution ultrastructural information from sparsely distributed targets - at multiple scales and in diverse biological structures.

    1. eLife assessment

      This fundamental work substantially advances our structural understanding of S-layers in Archaea and how they are built to form formidable cell support structures able to stabilise the cytoplasmic membrane under harsh physicochemical conditions. The supporting evidence for the S-layer model is convincing, making excellent use of state-of-the-art 3D cryo-electron tomography reconstructions, although the proposed S-layer model would benefit from some additional validation.

    1. eLife assessment

      This manuscript reports important findings in the field of developmental neurobiology, particularly in our understanding of human cortical development. The methods, data, and analyses are solid yet, the lack of clonal resolution or timelapse imaging makes it hard to assess whether the inheritance of centrosomes occurs as the authors claim.

    1. eLife assessment

      This study presents a valuable finding that erythrocyte precursors could re-gain EPO responsiveness after DFP chelation therapy. In addition, the authors investigated iron trafficking in erythroblasts using the MDS mouse model. However, the evidence supporting the claims of the authors is still inadequate. The work will be of interest to medical biologists working on hematology.

    1. eLife assessment

      This study transcriptomically profiles the developing zebrafish hindbrain from gastrulation through stages of rhombomere formation.

    1. eLife assessment

      This manuscript posits a novel role for the anterior cingulate cortex (ACC) in coding for sequential action strategies and the prevalence of each strategy. These findings provide important insight into ACC function and will therefore be of broad interest within the field of cognitive neuroscience. The evidence supporting the primary hypothesis is currently incomplete but could be rendered convincing with some further effort to rule out potential confounding factors.

    1. eLife assessment

      This well-written and well-reasoned manuscript describes a behavioral and computational modeling study designed to understand pure exploration, where action selection is driven by pure information seeking and not rewards. Using a novel task, the authors find that a subset of people use information value to drive their selection behavior, consistent with a simple information maximization model of reinforcement learning. The rest of the participants did not exhibit this behavior. This valuable work provides intriguing, yet somewhat incomplete, insights into understanding directed exploration and its computational form.

    1. eLife assessment

      This is an important study because it provides evidence that specific neuronal firing patterns in deep cerebellar nuclei map onto specific behavioral movement disorder phenotypes. The optogenetic manipulations and resulting neuronal and behavioral outcomes are highly compelling, but the development of the classifier tool was incomplete. This study contributes to the fields of cerebellar physiology and movement disorders because it puts forth a map of relationships between neuronal firing patterns and multiple distinct movement phenomena, providing a comprehensive, potentially fundamental, view that goes beyond most studies which typically examine one phenomenon in isolation.

    1. eLife assessment

      The manuscript from Richter et al. is a very thorough anatomical description of the external sensory organs in Drosophila larvae. It represents an important tool for investigating the relationship between the structure and function of sensory organs. Using improved electron microscopy analysis and digital modeling, the authors provide compelling evidence offering the basis for molecular and functional studies to decipher the sensory strategies of larvae to navigate through their environment.

    1. eLife assessment

      This work presents important findings for the field of Alzheimer's disease, especially for the electrophysiology subfield, by investigating the temporal evolution of different disease stages typically reported using M/EEG markers of resting-state brain activity. The evidence supporting the conclusions is solid and the methodology as well as the descriptions of the processes are of high quality, although a separation of individuals who are biomarker positive versus negative would have strengthened the interpretability of the results and the conclusions of the study.

    1. eLife assessment

      Lee and colleagues examined how neural representations are transformed between the olfactory tubercle (OT) and the ventral pallidum (VP) using single neuron calcium imaging in head-fixed animals trained in classical conditioning. They show that the dimensionality of neural responses is lower in the VP than in the OT. The study provides important results, and the data are overall solid although the reviewers thought some of the conclusions are not fully supported by the data and overstated, including the main conclusion that the OT neurons primarily encode odor identity but not value.

    1. eLife assessment

      This is an important study that provides detailed insights into the morphology of the lateral parietal cortex. Through this work new shallow sulci in the parietal cortex were identified and linked to function and behaviour. The evidence presented is convincing, even though some claims about the definition of highly variable sulci should be tampered down, and some important precisions about the labelling process are lacking to secure reproducibility. The present work both advances our understanding of the parietal cortex while also stimulating further debate on precise, detailed manual anatomy vs large scale automated data processing.

    1. eLife assessment

      In this study, the authors present convincing evidence to demonstrate theta cycle skipping by individual neurons of the lateral septum, which they then relate to population coding of future trajectories encapsulated by theta cycles. This valuable finding furthers our understanding of how the septum conveys navigational information downstream.

      This important manuscript presents the development and validation of an oral THC consumption mouse model utilizing highly palatable e-capsule gelatin. The results convincingly demonstrate suffient oral consumption to produce known THC behavioral and physiological effects, as well as brain levels. The utility of the model for chronic consumption remains to be determined. As the field of cannabinoid research moves toward modelling common routes of administration, these model systems will be important in assessing the effects of cannabinoid-based drugs.

      In uncertain conditions, decisions are not made in isolation but are rather biased by the recent past. This new work provides valuable insights into these history biases in human perceptual decision-making, by characterizing the neural correlates of stimulus history biases and their short-term dynamics. The study provides compelling behavioral and MEG evidence that humans adapt their history biases to the correlation structure of uncertain sensory environments.

    1. eLife assessment

      This valuable study identifies an Ephrin type-B Receptor 2 (EPHB2) interactor, MYCBP2, as a potential regulator of EPHB2 stability and function. In contrast to expectations, based on MYCBP2 function in the ubiquitin pathway, loss of function of MYCBP2 resulted in less EPHB2 receptor and defective EPHB2 function. The paper is supported by a largely convincing set of biochemical, cell culture and in vivo experiments.

    1. eLife assessment

      This is an important study that characterises the involvement of condensin complexes in the segregation of telomeres in fission yeast.

      For decades it has been accepted that only the growth-arrested "stumpy" form of Trypanosoma brucei can infect the arthropod vector, the Tsetse fly, but this was recently challenged by a demonstration that - under artificial conditions that are known to enhance infectivity - the proliferative "slender" form can also establish Tsetse infections. The infectiousness of the two forms is a fundamental question in trypanosome biology and epidemiology, concerning both infection dynamics and parasite differentiation. The authors of the current study provide independently compelling evidence that without artificial enhancement, the "stumpy" form is indeed much more infective for Tsetse than the slender form. The authors suggest that this is probably also true in the wild, but the precise reason for the discrepancy in results between the two laboratories remains unclear.

      This paper presents valuable insights into the implication of PI3Ka in heterotopic ossification (HO), and illustrates a potential therapeutic efficacy of BYL719 in suppressing HO within a murine model of Fibrodysplasia Ossificans Progressiva. While certain data are novel and compelling, others exhibit redundancies with prior publications and are inadequate in terms of methodology and presentation. Additionally, elucidating the precise molecular mechanisms of BYL719's action is imperative for a comprehensive understanding.

      This paper provides valuable information regarding visuospatial working memory performance in patients with MS compared to healthy controls, using a relatively novel continuous measure of visual working memory. There are some weaknesses with the way the clinical groups were matched, but those limitations are acknowledged and the strength of evidence for the claims is otherwise convincing. The paper will be of interest to those working in the field of clinical neuroscience.

      The manuscript describes the synergy among PI3Kβ activators, providing compelling results concerning the mechanism of their activation. The particular strengths of the work arise to a great extent from the reconstitution system better mimicking the natural environment of the plasma membrane than previous setups have. The study will be a landmark contribution to the signaling field.

      The fundamental findings reported here provide insight into how the viscoelasticity of the fingertip skin influences the activity of mechanoreceptive afferents and thus the neural coding of force in humans. The basic principle studied was whether and to what extent the previous applied force directions impact the firing of FA-1, SA-1 and SA-2 neurons during the current applied force directions. The data and analyses are compelling and will be helpful for modeling the neural representations of force in the context of object grasping and manipulation.

      This valuable study addresses the long-term effect of warming and altered precipitation on microbial growth, as a proxy for understanding the impact of global warming. While the methods are compelling and the evidence supporting the claims is solid, additional analysis of the data would strengthen the study, which should be of broad interest to microbial ecologists and microbiologists.

      This study presents valuable findings that examine both how Down syndrome (DS)-related physiological, behavioral, and phenotypic traits track across time, as well as how chronic treatment with green tea extracts 25 enriched in epigallocatechin-3-gallate (GTE-EGCG), administered in drinking water spanning prenatal through 5 months of age, impacts these measures in wild-type and Ts65Dn mice. However, the strength of the evidence is incomplete, due to high variability across measures, perhaps attributable to a failure to include sex as a factor for measures known to be sexually dimorphic. This study is of interest to scientists interested in Down Syndrome and its' treatment, as well as scientists who study disorders that impact multiple organ systems.

      This is an important study that revealed a new noncoding RNA regulatory circuit involved in T cell function. The authors provide compelling evidence, that is more rigorous than the state-of-the-art, using genetically engineered mice and cell-based experiments. The interpretation of the results should be tempered due to the small effect size observed.

      This paper presents a series of experiments investigating the role of cadherin-11 mediated interactions between cancer cells and fibroblasts in metastasis using updated 3D cell co-invasion assays. The primarily descriptive data are a valuable contribution to our understanding of the nature of cross cell-type interactions in metastasis, but are incomplete with respect to the far-reaching conclusions about the central role cadherin-11, especially given the complex nature of the phenotype and the need to better contextualize these observations in a complete picture of metastasis.

      The manuscript tackles a significant problem in addiction science: how interdependent are measures of "addiction-like" behavioral phenotypes? The manuscript provides evidence that escalation of intake, punishment-resistant responding, and breakpoints during a progressive ratio test may reflect a single underlying construct rather than reflect distinct unrelated measures. The exceptionally large sample size and incorporation of multiple behavioral endpoints add strength to this paper, and make it a useful resource for the field. However, in some ways the evidence presented in the manuscript is inadequate to support the broader conclusions, and the significance of the study is limited by statistical concerns and incomplete analysis of sex differences.

      This useful paper reports on two simple methods for improving the efficiency of prime editing, a prominent gene editing technique. In combination with published modifications, the strategies described in this study may lead to significant improvements in editing efficiencies. The data are solid, and the methods will be of broad interest to anyone using gene editing.

      This valuable study reports on the packing of molecules in cellular compartments, such as actin-based protrusions. The study provides solid evidence for parameters that enable the building of a biophysical model of filopodia, which is required to gain a complete understanding of these actin-based structures. Some areas of the manuscript require further clarification.

    1. eLife assessment

      This paper builds on a method, previously conceptualized and validated, of genetic control for insect populations. The method, called pgSIT, uses integrated CRISPR-Cas9 based constructs to generate, in certain combinations of genotypes, mutations that cause both male sterility and female inviability. Release of such genotypes in sufficiently large numbers can lead to an inundation of a local insect population with sterile males and this can lead to localised population suppression, which represents an important method of control for problematic insect populations. The data are convincing and will be of interest to anyone working on vector control strategies.

    1. eLife assessment

      This work suggests that behavior outcome information in the inferior colliculus persists in absence of top-down feedback from the auditory cortex. The results are valuable for researchers interested in how behavior impacts neural coding, as they urge us to focus the spotlight on non-cortical mechanisms of high-level activity in early auditory pathways. The topic and direct experimental methodology are compelling; however, the demonstration remains largely incomplete, as key information is missing to evaluate if a potential confound between sensory information and behavior outcome information is introduced in the analyses. This confound would strongly challenge the conclusion and more precise analyses of the sensory responses in IC and how they relate to behavioral outcomes would also be necessary to make the study more conclusive.

      This valuable study examines the evolution of the pillars in the shell architecture of organo-phosphatic brachiopods. The phylogenetic implications of this shell structure in relation to other early Cambrian brachiopod families are interpreted based on solid evidence. As such, this paper contributes to our understanding of the ecology and evolution of brachiopods as a whole.

      The work introduces two valuable concepts in antimicrobial resistance: "variant vulnerability" and "drug applicability", which can broaden our ways of thinking about microbial infections through evolution-based metrics. While the authors present a compelling analysis of a published dataset to illustrate how informative these metrics can be, the study is still incomplete as only a subset of a single dataset on a single class of antibiotics was analyzed. Analyzing more datasets, with other antibiotic classes and resistance mutations, and performing additional theoretical simulations could demonstrate the general applicability of the new concepts.

      The authors establish a Drosophila model to assess the severity of disease-linked alleles of Uba5 to study DEE44, a neurodevelopmental disease caused by UBA5 gene mutations. Using in vivo and in vitro experiments, this valuable study demonstrates that alleles fall into mild, intermediate, and severe classes, with convincing evidence to support their conclusion, which includes well-conserved relationships between UBA5 structure and function across humans and flies. This study establishes a model for further characterization of Uba5-related phenotypes in a powerful model system and will be used in the future to study the functional effects of these mutations on nervous system development.

      This study used ChatGPT to assess certain linguistic characteristics (sentiment and politeness) of 500 peer reviews for 200 neuroscience papers published in Nature Communications. The vast majority of reviews were polite, but papers with female first authors received less polite reviews than papers with male first authors, whereas papers with a female senior author received more favourable reviews than papers with a male senior author. Overall, the study is an important contribution to work on gender bias, but the evidence that generative AI programs like ChatGPT have the potential to be applied in meta-research is incomplete, especially given the lack of a comparison to the many existing and already-validated tools for sentiment analysis based on natural language processing.

      Satake and colleagues' important study elucidates somatic mutation processes in plants, demonstrating that in two tropical trees, mutation rates correlate with age, not growth rates. Their convincing evidence shows that many mutations do not align with cell divisions, suggesting many somatic mutations are generated in a replication-independent manner. This study represents a significant step towards advancing our understanding of plant development and the patterns and inheritance of mutations. This significant research is poised to engage a diverse array of scholars in plant evolution and development.

      P-glycoprotein (Pgp) is a major ABC-transporter that couples ATP hydrolysis with the export of xenobiotics and drugs, influencing their pharmacokinetics. The authors provide convincing cryo-EM Pgp structures of drug complexes in previously unforeseen outward-facing conformations. These structures reveal important mechanistic insights that could be of broader impact, but because these transient-like states were captured by cysteine cross-linking the substrate to Pgp, support for the conclusions is incomplete, and further validation is required.

      In this important study, the authors apply a residue-resolution protein coarse-grained model to investigate the differences in molecule dimensions and phase behaviour of three HP1 paralogs, HP1 paralog mixtures, and HP1/DNA mixtures. The simulations are well designed to investigate the impact of HP1 sequence on its phase behaviour. Solid evidence reveals that electrostatic interactions are a key determinant of HP1 paralog phase behaviour, thereby advancing our understanding of the molecular mechanisms driving the phase separation behaviour of HP1 paralogs.

      This valuable paper examines the Bithorax complex in several butterfly species, in which the complex is contiguous and not split, as it is in the well-studied fruit fly Drosophila. Based on genetic screens and genetic manipulations of a boundary element involved in segment-specific regulation of Ubx, the authors provide solid evidence for their conclusions, which could be further strengthened by additional data and analyses. The data presented are relevant for those interested in the evolution and function of Hox genes and of gene regulation in general.

      This study employs multiscale simulations to show that PIP2 lipids bind to the DIV S4-S5 linker within the inactivated state of a voltage-gated sodium channel, affecting the coupling of voltage sensors to the ion-conducting pore. The authors report the valuable finding that PIP2 prolongs inactivation by binding to the same site that binds the C-terminal tail during recovery from inactivation, suggesting binding to gating charges in the resting state that may impede activation. The coarse-grained and atomistic molecular dynamics simulations are solid, supporting the claims, although they do lack validation through experiment or simulation, such as studies of linker mutants to confirm PIP2 binding sites, a resting state Nav1.4 model to confirm voltage sensor binding, as well as tests using flexible linkers to probe interactions with PIP2 without backbone restraints.

      This important study advances our understanding of the biological significance of the DNA sequence adjacent to telomeres. The data presented convincingly demonstrates that subtelomeric repeats are non-essential and have a minimal, if any, role in maintaining telomere integrity of budding yeast. The work will be of interest to telomere community specifically and the genome integrity community more broadly.

      This valuable study provides molecular-level insights into the functional mechanism of bacterial ice-nucleating proteins, detailing important electrostatic interactions in the domain architecture of multimeric assemblies. The evidence supporting the claims of the authors is solid, with results from protein engineering experiments, functional assays, and cryo-electron tomography, while the proposed structural model of protein self-assembly remains hypothetical. The work is of broad interest to researchers in the fields of protein structural biology, biochemistry, and biophysics, with implications in microbial ecology and atmospheric glaciation.

      ZMYM2 is a transcriptional corepressor but little was known about how it is recruited to chromatin. This important study reveals that ZMYM2 homes to distinct classes of retrotransposons bound by the TRIM28 and ChAHP complexes in human cells, which is broadly relevant for the field of transcriptional regulation. Much of the evidence supporting the claims of the authors is convincing. Since widespread ZMYM2-mediated control of transposon activity is not apparent in RNA-seq data, further experiments are needed to demonstrate a more general role beyond the retrotransposons analysed in this study.

      Little is known about the role of the microbiome alterations in epithelial ovarian cancer. This important and rigorous study carefully examined the microbiome composition of 1001 samples from close to 200 ovarian cancer cases and controls, and presents compelling evidence that the fallopian tube microbiota are perturbed in ovarian cancer patients. These insights are expected to fuel further exploration into translational opportunities stemming from these findings.

      The presence or absence of a surrounding envelope, previously a clear distinguishing feature of different viruses, has been blurred by the recent recognition that many so-called 'nonenveloped' viruses are released from cells as quasi-enveloped virions cloaked in host cell membranes. This mechanism of viral egress allows for non-lytic infection, and has potentially important implications for pathogenesis. In this manuscript, Jassey and colleagues provide solid evidence that the protein deacetylase SIRT-1 is required for the non-lytic release of enteroviruses in extracellular vesicles.

      This study provides important information on the biogenesis of eccDNAs during spermatogenesis. The data presented are solid and supportive of the concussion that eccDNAs in spermatogenic cells are not derived from miotic recombination hotspots but rather represent oligonucleosomal DNA fragments from apoptotic male germ cells, whose ends are ligated through microhomology-mediated end-joining. This work is of interest to researchers working on germ cell biology and cancer biology.

      Despite the importance of T follicular helper cells (Tfh cells) in vaccine-induced humoral responses, it is still unclear which type of Tfh cells (Tfh1, Tfh2, and Tfh17) is critical for generating protective humoral immunity. By using the rhesus macaques model (most similar to human), the authors have addressed this potentially important question and obtained suggestive data that Tfh1 is critical. Although being suggestive, the evidence for the importance of Tfh1 is incomplete.

      This study presents a valuable finding on the function of the gene Cst7 in sex-divergent pathological changes in microglia in a mouse model of AB-driven Alzheimer's disease. The evidence supporting the claims of the authors is solid, although the study would be strengthened by validation of some of the key differentially expressed genes identified in RNA-sequencing experiments, and the inclusion of key controls and additional timepoints to address whether Cst7 drives disease progression or is simply upregulated as a result. The work will be of interest to neuroimmunologists and neuroscientists working on microglia and neurodegenerative disease.

      Picard et al. propose a Facial Expression Pain Signature (FEPS) as a distinctive marker of pain processing in the brain. In this valuable study, they attempt to use functional magnetic resonance imaging (fMRI) data to predict facial expressions associated with painful heat stimulation. The crucial aspect of the claim is whether the proposed biomarker is distinctive, i.e., it is specific enough to distinguish facial expressions in response to pain from similar facial expressions of non-painful origin. The experimental setup does not control for that condition, so the evidence is incomplete to support their main claims.

    1. eLife assessment

      This important study in Drosophila identifies neuronal mechanisms influenced by altered activity during a critical period (CP) of larval locomotor circuit development. Increasing activity during the CP causes permanent network changes indicating that a setpoint of network excitability is determined during the CP. Most importantly, for excitability setpoint determination during the CP excitatory and inhibitory inputs are integrated such that the effect of CP hyperexcitation can be rescued by the stimulation of endogenous inhibitory inputs to the motoneurons. Solid experimental evidence supports their novel insight into how developing neural network excitability is tuned and how it can be entrained during the CP.

To ensure the validity and robustness of the results, there is a need for additional controls and validations.

      This study presents a valuable insight into a computational mechanism of pain perception. The evidence supporting the authors' claims is solid, although the inclusion of 1) more diverse candidate computational models, 2) more systematic analysis of the temporal regularity effects on the model fit, and 3) tests on clinical samples would have strengthened the study. The work will be of interest to pain researchers working on computational models and cognitive mechanisms of pain in a Bayesian framework.

      The findings described in this manuscript are important and have theoretical or practical implications beyond a single subfield. Both reviewers comment on the strength of the paper because of the use of multiple approaches (optical imaging, physiology, rapid freeze EM, modeling, double mutant analysis).

      Gain-of-function mutations and amplifications of PPM1D are found across several human cancers and are associated with advanced tumor stage, worse prognosis, and increased lymph node metastasis. Unfortunately, clinical translation has so far not been possible due to the lack of PPM1D inhibitors with favorable pharmacokinetic properties. This useful study leveraged CRISPR/Cas9 screening to identify that SOD1 inhibition is synthetic lethal with PPM1D mutation in leukemia, although the mechanistic analyses were incomplete.

      This study presents compelling observations of the ability of Ym1 crystals to promote type 2 immunity in vivo, in mice, that advances our knowledge of how the abundantly expressed chitinase-like protein family may function, with new methodology, new crystal structures that are more rigorous than what is currently known and very convincing immunological data. The significance of the study is important, providing an exciting opportunity to mechanistically study the impact of protein crystals in vivo in relation to human disease. This work will be of broad interest to immunologists and researchers working on type 2 inflammatory disease, in the lung.

Nevertheless, both reviewers have raised questions to be addressed, at which time this work will be of broad interest to immunologists specifically, and biologists in general.

    1. Evaluation statement (1 September 2023)

      Flores-Aldama and colleagues set out to identify molecular determinants of fast inactivation in the TRPV6 ion channel, a mechanism not observed in the closely related TRPV5 channel. The work focuses on a helix-loop-helix (HLH) motif, located at the interface between several important regions for channel gating. Using molecular dynamics simulations and analysis of mutations, the authors identify pairs of amino acid residues in a structural triad formed by the HLH, S2-S3 linker, and transmembrane domains, which show different conformations in the available TRPV5 and TRPV6 cryo-EM structures. An important aspect of the study is that some of the structural hypotheses were derived from an evolutionary analysis of sequences from orthologues of both channels, demonstrating the value of this type of analysis.

      Biophysics Colab considers this to be a convincing study and recommends it to scientists interested in the molecular determinants of ion channel gating.

      (This evaluation by Biophysics Colab refers to the version of record for this work, which is linked to and has been revised from the original preprint following peer review.)

      This valuable manuscript investigates the role of a subpopulation of glutamatergic neurons in the suprammamillary nucleus that projects to the pre-optic hypothalamus area in active coping but not locomotor activity. It provides solid evidence from experiments using fibre photometry or photostimulation during threatening tasks that these neurons allow animals to produce flexible behaviours in response to stress. However, the evidence is incomplete in several ways, including validation and quantification of anatomical tracing data that serve as a basis for the behavioral testing, the use of statistics, sex as a biological variable, genotype differences between experimental and control groups in behavioral tests, limiting its broad interest to neuroscientists across sub-fields.

      This paper measures the neural activity in reach-to-grasp and reach-only tasks using intrinsic optical imaging. The paper describes these in the relationship to the Intra-cortical micro stimulation maps of the same animals. The dataset is unique and potentially highly important. However, the claim of "clustered neural activity" is not tested against any quantifiable alternative hypothesis of non-clustered activity, and support for this idea is therefore currently incomplete.

      This study uncovers a unique feature of the nucleotide binding domain interface in human CFTR, offering valuable insights into the effects of different non-hydrolytic mutations on CFTR gating. While the evidence presented is solid, a more thorough examination of the non-hydrolytic mutants of zebrafish CFTR for comparison would strengthen the authors' claims. In the current form, more cautious interpretations of some of the data are needed.

      This important study examines the existence of a fear memory engram in acetylcholine neurons of the basal forebrain and seeks to link this to modulation of amygdala for fear expression. Using a combination of techniques including genetic access to cFos expressing neurons, in-vivo chemogenetics, and optical detection of acetylcholine (ACh), the authors present solid evidence that posteriorly-located amygdala projecting basal forebrain cholinergic neurons participate in cue-specific threat learning and memory. This paper will be of interest to those studying circuit-level mechanisms of learning and emotion regulation.

      This is an important study of the mechanism of how binding of the fatty acid myristic acid (MYR) inhibits the activity of the kinase c-Abl, a critical regulator of many cellular processes. While the general aspects of this regulation are known from structure determination and biochemical studies, the exact molecular mechanism and the nature of the allosteric inhibition were not known. The authors use MD simulation to close this gap and provide a detailed mechanistic description of the inhibitory mechanism, although some of the evidence remains incomplete.

      This valuable multicenter study provides solid evidence that the auditory noise emitted during online transcranial ultrasound stimulation (TUS) protocols can pose a considerable confound and is able to explain corticospinal excitability changes as measured with Motor Evoked Potentials (MEP). The findings may lay the ground for future studies optimizing protocols and control conditions to leverage transcranial ultrasound stimulation as a meaningful experimental and clinical tool. A clear strength of the study is the multitude of control conditions (i.e., control sites, acoustic masking, acoustic stimulation).

      This is an important study that improves gene models for the ferret genome and identifies neural progenitors that are comparable to those found in developing human brains. The data are convincing and clearly presented. Of particular interest to the field, the work identifies enriched expression of FOXJ1 in late truncated radial glia, strongly indicating that towards the end of neurogenesis, these cells likely give rise to ependymal cells. The work is of interest to anyone studying the development of the nervous system, especially colleagues studying the evolution of development.

      This study combines CLIP, RNA-seq, and splicing assays with manipulation of RBMX and its homologs RBMY and RBMXL2 to show that the RBMX family suppresses the recognition of cryptic splicing within long exons. The study is important in that it puts forward the intriguing claim that the RBMX family is responsible for the cryptic splice site repression in ultra-long exons. The methods, data, and analyses supporting the claims are solid, broadly supporting the claims, with some weaknesses. The generalization of the findings is somewhat overstated but could be strengthened by deeper statistical integration of the RNA-seq and CLIP datasets.

      This important manuscript focuses on the mechanisms by which food signals and food ingestion modulate animal foraging. The authors provide solid support for the interesting idea that chemosensory and interoceptive signals converge on transcriptional regulation of the TGF-beta ligand DAF-7 in a single pair of C. elegans chemosensory neurons to regulate behavior. Their studies implicate a conserved signaling molecule, ALK, in this regulation, suggesting a conserved link between food cues and the neuroendocrine control of foraging behavior.

      This study presents potentially useful findings describing how activity in the corticotropin-releasing hormone neurons in the paraventricular nucleus of the hypothalamus modulates sevoflurane anesthesia, as well as a phenomenon the authors term a "general anesthetic stress response". The technical approaches are solid and the data presented are largely clear. However, the primary conclusion, that the PVHCRH neurons are a mechanism of sevoflurane anesthesia, is inadequately supported.

      The presented study introduces a valuable non-AI computational method for segmenting noisy grayscale images, particularly highlighting its applicability in identifying immunostained potassium ion channel clusters. While the method's avoidance of AI training appeals to those lacking computational know-how and shows improved accuracy over basic threshold-based techniques, there are valid concerns regarding its performance in comparison to advanced methodologies. The evidence supporting the method's efficacy is solid but incomplete, necessitating comparisons to more advanced techniques and the provision of user-friendly computational tools for a comprehensive evaluation.

      This work is valuable in exploring the role of nutritional immunity in bacteria-mediated tumor therapeutics, involving proteomics and in vivo mouse model results which provide largely solid supporting evidence of the observational claims, but is incomplete when extrapolating the mechanisms of how manipulation of iron status can affect E. coli-mediated tumor therapy. This work is of interest to a broad audience including researchers in cancer biology, cell biology, and microbiology.

      This valuable manuscript systematically addresses the role of intracellular lipid transfer proteins on cellular lipid levels. The authors have provided solid evidence on the role of ORP9 and ORP11 in sphingolipid metabolism at the Golgi complex. The data is in general convincing, except for the claim that ORP9/11 might counter-exchange phosphatidylinositol 4-phosphate and phosphatidylserine, which is not fully supported by the data presented. This article will be of broad interest to cell biologists interested in lipid metabolism and membrane biology.

      This study presents valuable new findings on the role and mechanism of action of the poorly characterized cell surface protein TMEM263 in regulating mouse postnatal growth. The evidence supporting the whole-body growth and skeletal phenotypes, as well as the disruption of GH/insulin-like growth factor-1 (IGF-1) signaling seen in TMEM263 knockout mice, is convincing. However, additional data are needed to definitively conclude that the observed alteration of hepatic GH/IGF1 signaling is causative of the body growth and skeletal phenotypes.

      This study presents valuable findings on the organization of respiratory chain complexes in mitochondria. It provides solid evidence that respiratory supercomplex formation in the fruit fly does not impact respiratory function, suggesting the role of these complexes is structural, rather than catalytic. However, whether the conclusions extend to other species requires further evidence. This manuscript will be of broad interest to the field of mitochondrial bioenergetics.

    1. eLife assessment

      This fundamental study substantially advances our physical understanding of the sharp increase and saturation of the viscosity of non-confluent tissues with increasing cell density. Through the analysis of a simplified model this study provides compelling evidence that polydispersity in cell size and the softness of cells together can lead to this phenomenon. The work will be of general interest to biologists and biophysicists working on development.

    1. eLife assessment

      This paper provides important insights into how asexual reproduction can arise in interspecific hybrids. The evidence supporting the conclusions is compelling, with rigorous molecular cytogenetic experiments showing the production of clonal gametes is common across hybrids between closely to moderately divergent sexual species. By highlighting the potential for asexuality to evolve in hybrids during a narrow window of species divergence, this work will be of broad interest to evolutionary biologists.

    1. eLife assessment

      The authors discuss an effect, "diffusive lensing", by which particles would accumulate in high-viscosity regions, for instance in the intracellular medium. To obtain these results, the authors rely on agent-based simulations using custom rules performed with the Ito stochastic calculus convention. The "lensing effect" discussed is a direct consequence of the choice of the Ito convention without spurious drift which has been discussed before and is likely to be inadequate for the intracellular medium, causing the presented results to likely have little relevance for biology.

      This important study combines cellular assays and biophysical methods to identify heparan sulfate (HS) as a regulator of apoptosis. The multidisciplinary approach for investigating HS•TRAIL interactions is highly compelling, but the central hypothesis could be further strengthened from additional investigations on downstream effects. This paper is very relevant to cancer biologists and biophysicists working on TRAIL-dependent apoptotic pathways.

      This valuable work by Pulfer et al. advances our understanding of spatial-temporal cell dynamics both in vivo and in vitro. The authors provide convincing evidence for their innovative deep learning-based apoptosis detection system, ADeS, that utilizes the principle of activity recognition. Nevertheless, the work is incomplete due to the authors' claim that their system is valid for non-fluorescently labeled cells, without evidence supporting this notion. After revisions, this work will be of broad interest to cell biologists and neuroscientists.

    1. eLife assessment

      This study presents a valuable finding that serum androstenedione levels may provide a new biomarker for early detection and progression of glaucoma, although a single biomarker is unlikely to be singularly predictive due to the etiological heterogeneity of the disease. The strength of the evidence presented is solid, supported by multiple lines of evidence.

      This valuable study evaluates the effects of nifuroxazide on radiotherapy for the treatment of hepatocellular carcinoma. Solid evidence is provided to support the conclusion that nifuroxazide facilitates the downregulation of PD-L1 and may improve outcomes when combined with radiotherapy, though the inclusion of additional cell lines and animal models would have strengthened the study. This work will be of interest to cancer biologists and those working in immuno-oncology.

    1. eLife assessment

      These solid results demonstrate that arpin is expressed in the endothelium of blood vessels and its deficiency leads to leaky blood vessels in in vivo and in vitro models, although the work does not clarify the mechanistic connection between arpin and increased ROCK activity. The study adds some insights to our understanding of the complicated network of proteins that control this process, and it will be useful to individuals within this defined field of study.

      Studying several allergens in different mouse strains, the authors assess the role of IgM in airway inflammatory responses and show that IgM deficient mice have reduced airway hyperresponsiveness. Although the findings, based on experimental evidence from a wide range of immunological and other assays, including the expression of a protein that regulates actin in smooth cells, are interesting and useful, the study is incomplete as the data and analyses do not support their primary claims.

      This solid study presents valuable insights into the role of Cers1 on skeletal muscle function during aging, although further substantiation would help to fully establish the experimental assertions. It examines an unexplored aspect of muscle biology that is a relevant opening to future studies in this area of muscle research.

    1. eLife assessment

      Despite the importance of long-lived plasma cells (LLPCs), particularly in the vaccination field, their natures are still unclear. In this valuable manuscript, as a first step towards clarifying these natures, the authors used a solid genetic approach (time-stamping one) and successfully labelled only functional LLPCs. Although four groups have already published data by the same genetic approach, the authors' manuscript includes additional significant findings in the LLPC field.

    1. eLife assessment

      This manuscript presents a valuable approach to exploring CD4+ T-cell response in mice across stimuli and tissues through the analysis of their T-cell receptor repertoires. The authors use a transgenic mouse model, in which the possible diversity of the T-cell receptor repertoire is reduced, such that each of a diverse set of immune exposures elicits more detectably consistent T-cell responses across different individuals. However, whereas the proposed experimental system could be utilized to study convergent T-cell responses, the analyses done in this manuscript are incomplete and do not support the claims due to limitations in the statistical analyses and lack of data/code access.

    1. eLife assessment

      The authors' finding that PARG hydrolase removal of polyADP-ribose (PAR) protein adducts generated in response to the presence of unligated Okazaki fragments is important for S-phase progression is potentially valuable, but the evidence is incomplete, and identification of relevant PARylated PARG substrates in S-phase is needed to understand the role of PARylation and dePARylation in S-phase progression. Their observation that human ovarian cancer cells with low levels of PARG are more sensitive to a PARG inhibitor, presumably due to the accumulation of high levels of protein PARylation, suggests that low PARG protein levels could serve as a criterion to select ovarian cancer patients for treatment with a PARG inhibitor drug.

    1. eLife assessment

      This valuable study describes a new role of epithelial intercellular adhesion molecule 1 (ICAM-1) protein in controlling bile duct size. The effect is mediated via EBP-50 and subapical actomyosin to regulate size of bile canaliculi. These solid findings have theoretical and practical implications in hepatology and human disorders of bile ducts.

    1. eLife assessment

      This study provides a useful description of two evolutionary conserved motifs in CD4 that contribute to the CD4-mediated enhancement of T cell receptor (TCR) signaling, which are notably acting independently of the CD4-LCK interaction. The supporting evidence is solid and supported using a T cell hybridoma in vitro system, but remains incomplete without experiments with primary T cells or the use of in vivo models to assess the importance of the CD4 motifs in T-cell biology.

    1. eLife assessment

      This important work identifies a previously uncharacterized capacity for songbirds to recover vocal targets even without sensory experience. While the evidence supporting this claim is solid, with innovative experiments exploring vocal plasticity in deafened birds, additional behavioral controls and analyses are necessary to shore up the main claims. If improved, this work has the potential for broad relevance to the fields of vocal and motor learning.

    1. eLife assessment

      In this important study, the rabbit was used as a non-rodent mammalian model to show that DMRT1 has a testicular promoting function as it does in humans. The experiments are meticulous and compelling, and the arguments are clear and convincing. These results may explain the gonadal dysgenesis associated with mutations in human DMRT1 and highlight the need for mammalian models other than mice to better understand the process of gonadal sex determination in humans.

    1. eLife assessment

      This study presents Bactabolize, a valuable tool for the rapid genome-scale reconstruction of bacteria and the prediction of growth phenotypes. Using validated methodology, the tool relies on a reference pan-genome model to create strain-specific draft metabolic models, as demonstrated in this study using Klebsiella pneumoniae. While the evidence in this specific case is solid, validation across diverse bacterial species is yet to be confirmed.

    1. eLife assessment

      This is an important study showing how dendritic plateau potentials can enable neurons to perform reliable 'binary' computations in the face of realistic spike time jitter in cortical networks. The authors make a surprising and novel claim that dendritic plateau potentials perform equally well in short integration windows of only 10 ms and detail a biophysical mechanism for how this effect may occur. While the authors make many good arguments, and the general concept underlying the paper is sound, the evidence as of now is incomplete, with some unsupported statements that should be more thoroughly defended in the manuscript.

      Chen and colleagues utilize an in situ explant model of the neural retina and retinal pigment epithelium (RPE), along with small molecule inhibition of key metabolic enzymes and targeted metabolomic analysis, to decipher key differences in metabolic pathways used by rods, cones, Muller glia, and the RPE. They conclude that rods are heavily reliant on oxidative metabolism, cones are heavily reliant on glycolysis, and multiple mechanisms exist to decouple glycolysis from oxidative metabolism in the retina. This study provides valuable metabolomic data and insights into the metabolic flexibility of different retinal cells. However, the evidence supporting the authors' claims is incomplete and would benefit from validating their evidence with animal models, comparing their data to previously published literature, performing C13 tracing experiments, and assessing mitochondrial function.

    1. eLife assessment

      This valuable study shows that distinct midbrain dopaminergic axons in the medial prefrontal cortex respond to aversive and rewarding stimuli and suggest that they are biased toward aversive processing. The use of innovative microprism based two-photon calcium imaging to study single axon heterogeneity is solid, although the experimental design could be optimized to distinguish aversive valence from stimulus salience and identity in this dopamine projection. This work will be of interest to neuroscientists working on neuromodulatory systems, cortical function and decision making.

      This work identifies cnidarian neuropeptides and pairs them to their GPCR, then shows that neuropeptide signaling systems have evolved and diversified independently in cnidarians and bilaterians. Neuropeptide-receptor partners were experimentally identified using established and widely used methodologies including single cell mapping, providing compelling evidence for the conclusions of the paper. This impressive accomplishment provides fundamental new insights into the evolution of neuropeptide signaling systems and will be of broad interest to neurobiologists and evolution of development researchers.

    1. eLife assessment

      The study by Chardon et al. is fundamental to advancing our understanding of presynaptic control of motor neuron output. Large-scale computer simulations were performed using well-established single motor neuron models to provide compelling evidence regarding the time-varying patterns of inputs that control motor neuron ensembles. The work will interest the community of motor control, motor unit physiology, neural engineering, and computational neuroscience.

    1. eLife assessment

      In this valuable study, Parrotta et al. showed that it is possible to modulate pain perception and heart rate by providing false heart rate (HR) acoustic feedback before administering electrical cutaneous shocks. The evidence supporting the claims of the authors is rather solid, although what they consider an interoceptive signal is not necessarily supported as such by the results. In this regard, including a larger number of trials per participant, increasing the sample size, and adding a measure of actual pain perception after its induction would have strengthened the study. Although mechanisms and some alternative explanations for this effect remain to be addressed, the work will nonetheless be of interest to neuroscientists working on predictions and perception, health psychologists, pain researchers, and placebo researchers.

    1. eLife assessment

      The study presents valuable insights into the regulation of astrocytes in the long-term potentiation of excitatory synapses onto inhibitory interneurons. However, reviewers identified concerns regarding originality and proper acknowledgment of replicated work, representation of interneuron diversity, and the robustness of certain conclusions. The strength of evidence provided is deemed incomplete, necessitating significant revisions for clarity, and accuracy, and to address highlighted concerns.

    1. eLife assessment

      This valuable study uses a combination of behavioral studies and computational modeling to argue that humans implicitly represent gravity as a Gaussian distribution (rather than as a deterministic vector). The experimental evidence is generally solid, with all experiments and model simulations being consistent with the proposed account. However, in the current version of the manuscript, the evidence for the main claim of the paper is incomplete: a number of alternative interpretations such as uncertainty about the presence of external lateral forces, or uncertainty about other object properties have not been considered sufficiently.

    1. eLife assessment

      The authors have updated a helpful resource for the neuroscience community regarding hippocampal cell types and their interactions, called the "hippocampome." The updates expand content, tools, and potential applications, and therefore the significance is important. The strong presentation makes the paper compelling.

    1. eLife assessment

      This valuable study analyzed a large cohort of Adolescent Idiopathic Scoliosis (AIS) patients and identified an association with a variant in COL11A1 (Pro1335Leu). Experimental testing of this potentially pathogenic variant suggests a link between Pax1, Col11a1, Mmp3, and estrogen signaling. While the connection between transcriptional regulation, the extracellular matrix, and estrogen signaling is compelling, the experimental evidence supporting this link is still incomplete and would benefit from a more direct and comprehensive approach. Strengthening the functional testing would help establish the pathogenicity of a collagen variant and the role of the proposed Pax1-Col11a1-Mmp3 signaling axis in AIS.

    1. eLife assessment

      This paper presents important new data related to the non-canonical SMC complex MukBEF in E. coli, which remains less well understood compared to more canonical SMC complexes in many other bacteria. The authors use a combination of Hi-C and ChIP-seq to demonstrate that MukBEF loads at multiple locations along the chromosome, preferentially in newly replicated DNA, with the MatP/matS system antagonizing MukBEF activity and localizing in terminus proximal regions. Most of the data to support these findings are compelling, with modest concerns raised about the effect sizes of the ChIP-seq data, which could be bolstered with some additional controls.

    1. eLife assessment

      This fundamental study provides compelling evidence to explain how chemical variations within a set of kinase inhibitors drive the selection of specific Erk2 conformations. Conformational selection plays a critical role in targeting medically relevant kinases such as Erk2 and the findings reported here open new avenues for designing small molecule inhibitors that block the active site while also steering the population of the enzyme into active or inactive conformations. Since protein dynamics and conformational ensembles are essential for enzyme function, this work will be of broad interest to those working in drug development, signal transduction, and enzymology.

      This is a valuable contribution to the electric fish community, and to studies of active sensing more generally, in that it provides evidence that a well-studied behavior (chirping) may serve in active sensing rather than communication. For the most part, the evidence is solid. In particular, the evidence showing increased chirping in more cluttered environments and the relationship between chirping and movement are convincing. Nevertheless, evidence to support the argument that chirps are mostly used for navigation rather than communication is incomplete.

      The authors investigate the mechanism of amyloid nucleation in a cellular system using novel ratiometric measurements, providing fundamental insight into the role of polyglutamine length and the sequence features of glutamine-rich regions in amyloid formation. The problem addressed by this study is very significant and the ability to assess nucleation in cells is of considerable value. The data, as presented and analyzed, are mostly convincing.

      While Bacterial Artificial Chromosomes libraries were once a key resource for building the human genome project over time they have been rendered relatively obsolete by long-read technologies. In the era of CRISPR-Cas systems pairing this data with one of the many guide-RNA libraries to find targets for manipulation with CRISPR tools is bringing back BACs advantages for genomics. With this in mind the authors have developed a BAC restriction map database containing the restriction maps for both uniquely placed and insert-sequenced BACs from 11 libraries covering the recognition sequences of available restriction enzymes. Alongside a set of Python functions to reconstruct the database and more easily access it (which were debugged and had improved documentation added during review). The presented data should be valuable for researchers simply using BACs, as well as those working with larger sections of the genome in terms of synthetic genes, large-scale editing, and mapping.

      This work presents a new standardized graphical approach for visualizing genetic associations across a wide range of allele frequencies. These proposed TrumpetPlots have a distinctive trumpet shape, hence the proposed name. With the majority of variants having low frequency and small effects, while a small number of variants have higher frequency and larger effects, this view can help to provide new and valuable insights into the genetic basis of traits and diseases, and also help prioritize efforts to discover new risk variants. The tool is provided as a novel R package and R Shiny application and to demonstrate its use the article illustrates the distribution of variant effect sizes across the allele frequency range for over 100 continuous traits available in the UK Biobank. After some problems in testing the package is now available and easy to deploy via CRAN.

      This is an important biophysical study combining native mass spectrometry with mutant cycles to estimate the thermodynamic components of lipid A binding to the ABC transporter MsbA. Binding energies for lipid-protein interactions are proposed, but the evidence is currently incomplete as they rely on a number of technical and theoretical assumptions, mostly related to multiple lipid binding sites in the protein.

      The manuscript represents an important contribution to an ongoing discussion about the substrate binding site and mechanism of the Bile Acid Sodium Symporter (BASS) family of transporters. Structural and biochemical analysis of a bacterial homolog, ASTBnm, in complex with its native substrate (not bile acids, but a vitamin A precursor, pantoate) show a new binding site that is consistent with classical proposals for elevator-type transport mechanisms. Molecular dynamics (MD) simulations highlight the improved stability for the substrate in the active site when ions are present, suggesting a binding order during the transport cycle. The structural studies, binding assays, and MD simulations are convincing.

      This important study combines a range of advanced ultrastructural imaging approaches to define the unusual endosomal system of African trypanosomes. Compelling images show that instead of a distinct set of compartments, the endosome of these protists comprises a continuous system of membranes with functionally distinct subdomains as defined by canonical markers of early, late and recycling endosomes. The findings suggest that the endocytic system of bloodstream stages has evolved to facilitate the extraordinarily high rates of membrane turnover needed to remove immune complexes and survive in the blood, which is of interest to anyone studying infectious diseases.

    1. eLife assessment

      This important study addresses mechanisms of feedback inhibition between planar cell polarity (PCP) protein complexes during convergent extension movements in Xenopus embryos. The authors propose an interesting model, in which non-canonical Wnt ligand stimulates transition of Dishevelled from its complex with Vangl to Frizzled, with essential roles of Vangl, Prickle and Ror in this process. The main functional observations supporting this model are convincing, but the immunoprecipitation data are incomplete and would benefit from additional clarification. With more rigorous approaches, this work will likely be of broad interest to cell and developmental biologists.

      In this manuscript by Xiong L et al., through TLR2, the authors have uncovered an important link between innate immune signaling and hair regeneration. The authors provide convincing evidence supporting the critical roles of TLR2 in sensing CEP levels in hair follicles, counteracting the action of BMP signaling, and facilitating the activation of HFSCs during the hair cycle and wound repair. Importantly, the authors also propose that decreased CEP production and TLR2 expression might be factors contributing to the decreased hair regeneration associated with age-related and obesity-related hair thinning and hair loss phenotypes.

      The biogenesis of outer membrane proteins in Gram-negative bacteria is still not fully understood, particularly substrate recognition and insertion by beta-assembly machinery. This work reports important results identifying a new amino acid sequence motif (i.e., "internal beta-signal") on outer membrane proteins recognized by this machinery. The authors carried out rigorous biochemical approaches, providing convincing evidence to support their conclusions.

    1. eLife assessment

      This important study advances our understanding of early Cambrian cnidarian paleoecology and suggests that the reconstructed ancestral feeding and respiration mechanisms predate jet-propelled swimming utilized by modern jellyfish. The work combines solid evidence of fluid and structural mechanics modeling, simulating for the first time the feeding and respiratory capacities in a microfossil (Quadrapyrgites), which in turn opens new possibilities using this approach for paleontological research. Assuming that the prior interpretations and assumptions concerning the modeled organism's soft part and skeletal anatomy are correct, the hypotheses that (1) the organism could alternately contract and expand the oral region and (2) such movement increased feeding efficiency seem plausible.

      This important study uses near full-length HIV-1 sequencing to examine proviral persistence in various tissues derived from three individuals who received antiretroviral therapy until time of death. Intact as well as defective HIV-1 proviruses are found at various anatomical sites including the central nervous system; the results are convincing and relevant for our understanding of latent viral reservoirs, especially in the brain.

      The study presented in this manuscript makes important contributions to our understanding of cell fate decisions, as well as to the role and effects of noise at various scales in gene regulatory networks involved in such fate decisions.

      This study examines the role of interaction between the PAS domain and the Cyclic Nucleotide-Binding Homology Domain (CNBHD) in voltage-dependent gating of EAG channels. The authors make the extraordinary claim that they have identified a hidden open state, thus providing a window for observing early conformational transitions associated with channel gating. Although the data are intriguing, the evidence supporting the conclusions is incomplete, and the experimental conditions used to propose the channel gating mechanism need to be revisited. With sufficiently strong experimental support, this work could become important for understanding the gating mechanisms of the KCNH family and would appeal to biophysicists interested in ion channels and physiologists interested in cancer biology.
