This work presents a valuable data-driven method to extract the "true" synaptic plasticity rule (or learning rule) operating in a neural circuit from empirical measurements of neural activity. The approach aims to train a generative adversarial network (GAN) to match neural activity measurements in terms of statistics, learning them from the data, rather than being pre-determined by the experimenter. The main conclusion is that the extracted learning rules are not unique, but rather degenerate, meaning that multiple plasticity rules can produce the same neural activity. Although the paper presents a thorough investigation using one learning rule as a case study (the Oja rule), the evidence that the results can be inferred beyond the specific numerical experiments presented in the paper is incomplete.

eLife assessment

This valuable paper by Yao, Dai, and colleagues describes a viral gene drive against herpes simplex virus 1 in cell culture. The authors provided solid evidence that an engineered gene drive sequence, expressing either spCas9 or Un1Cas12f1 nuclease, could spread efficiently in the population of wild-type viruses and induce fewer drive-resistant mutations than spCas9. Limitations include a mechanistically inaccurate title, several methodologic flaws, and a paucity of descriptions of possible therapeutic applications.

eLife assessment

This fundamental work significantly advances our understanding of how FOG1 nuclear localization is regulated during erythropoiesis and megakaryopoiesis, including the role of EPO and MPL/TPO signaling in this process. The authors provide compelling evidence using both K562 and CD34+ cells that heat shock cognate B (HSCB) can promote the proteasomal degradation of TACC3 to regulate the nuclear localization of FOG1, and that this function is independent of its role in iron-sulfur cluster (ISC) biogenesis. The conclusions would be strengthened in the future by the use of in vivo model systems, however, as written, this work will be of broad interest to cell biologists.

This article provides a review and test of image-analysis methods for bacteria growing in the 'mother-machine' microfluidic device, introducing also a new graphical user interface for the computational analysis of mother-machine movies based on the 'Napari' environment. The tool allows users to segment cells based on two previously published methods (classical image transformation and thresholding as well as UNet-based analysis), with solid evidence for their robust performance based on comparison with other methods and use of datasets from other labs. While it was difficult to assess the user-friendliness of the new GUI, it appears to be valuable and promising for the field.

eLife assessment

This valuable study informs on the regulation of metabolic flux between glycolysis and respiration in yeast, mediated by inorganic phosphate. The authors propose a novel mechanism involving Ubp3/Ubp10 that potentially mitigates the Crabtree effect, based on an array of assays that offer substantial insight into mitochondrial biogenesis under high glucose conditions. However, the evidence supporting the conclusions remains incomplete because of a limited number of replicates, particularly in protein blot analyses with insufficient normalization methods, which undermines the robustness of the findings. This work could influence the subfield significantly if the methodological weaknesses are addressed to provide more support for the proposed model.

eLife assessment

This valuable study examines the evolution of the pillars in the shell architecture of organo-phosphatic brachiopods.

eLife assessment

This study reports an important finding highlighting the essential role of the putative ion channel, TMC7 (transmembrane channel-like 7) in male fertility, thereby significantly advancing our understanding of the function of the previously uncharacterized protein in sperm development. The evidence supporting TMC7's requirement in acrosome biogenesis during spermatogenesis is solid, and its function as an ion channel requires more study.

eLife assessment

This valuable study addresses how distinct cilia lengths of different cell types in zebrafish are regulated and proposed an interesting mechanism. While the quality of imaging and the resources generated in this study are excellent, key experimental information is not always provided and the strength of evidence to support the proposed hypothesis on ciliary length regulation is currently incomplete.

The findings are useful, but the study remains incomplete as the effect on biosensor assays was not established.

eLife assessment

This valuable study presents findings that suggest the need for postoperative type 2 diabetes screening and that this should be prioritized in colorectal cancer survivors with overweight/obesity regardless of the type of colorectal cancer treatment applied. The evidence supporting the claims of the authors is solid and the authors use a population-based cohort study including all Danish colorectal patients who had undergone colorectal cancer surgery between 2001-2018. The work will be of interest to medical biologists, endocrinologists and oncologists working on colorectal cancer.

eLife assessment

Pin1 as an essential prolyl cis/trans isomerase has attracted considerable attention because this enzyme family is implicated in cancer and neurodegenerative diseases. However, the requirement for its catalytic function remains a matter of dispute. The authors provide solid evidence that Pin1 modulates the activity of an important cell signaling kinase, Protein Kinase C, by a non-catalytic mechanism, acting as a chaperone to regulate the stability of this kinase.

eLife assessment

This computational study is a valuable empirical investigation into the common trait of neurons in brains and artificial neural networks: responding effectively to both objects and their mirror images and it focuses on uncovering conditions that lead to mirror symmetry in visual networks and the evidence convincingly demonstrates that learning contributes to expanding mirror symmetry tuning, given its presence in the data. Additionally, the paper delves into the transformation of face patches in primate visual hierarchy, shifting from view specificity to mirror symmetry to view invariance. It empirically analyzes factors behind similar effects in two network architectures, and key claims highlight the emergence of invariances in architectures with spatial pooling, driven by learning bilateral symmetry discrimination and importantly, these effects extend beyond faces, suggesting broader relevance. Despite strong experiments, some interpretations lack explicit support, and the paper overlooks pre-training emergence of mirror symmetry.

With these matters addressed, this work will be of great interest to the fields of vector-borne disease control and host-pathogen interaction.

eLife assessment

This study presents valuable findings that expand our view of dopamine release in different brain regions and show that dopamine release in the lateral hypothalamus is related to the activity of orexin neurons. The evidence supporting the claims of the authors is solid, although inclusion of tests that directly assess causality of the noble pathways would have been even more conclusive. The work will be of interest of neuroscientists who study the neural basis of motivation.

The finding of waves of membrane potential would be of interest to a wide audience from molecular biology to microbiology and physical biology. Unfortunately, a major issue with the experimental technique affects the interpretation of the observations: the dye used has been previously shown not to report membrane potential, leaving the evidence inadequate.

eLife assessment:

The study answers the important question of whether the conformational dynamics of proteins are slaved by the motion of solvent water or are intrinsic to the polypeptide. The results from neutron scattering experiments, involving isotopic labelling, carried out on a set of four structurally different proteins are convincing, showing that protein motions are not coupled to the solvent. A strength of this work is the study of a set of proteins using spectroscopy covering a range of resolutions, however, it suffers from some scholarly shortcomings and limited discussion of results. The work is of broad interest to researchers in the fields of protein biophysics and biochemistry.

eLife assessment

This is an important study examining the role of prediction error in state allocation of memories. The data are convincing and largely support the conclusion that a gradual change between acquisition and extinction maintains the memory state of acquisition and, thus, results in extinction that is resistant to restoration. This paper is of interest to behavioural and neuroscience researchers studying learning, memory, and the neural mechanisms of those processes, as well as to clinicians using extinction-based therapies in treating anxiety-based disorders.

eLife assessment

The findings in this manuscript are important and novel, and the genomic analyses are convincing. This study expands upon our understanding of the role of hnRNP proteins in lncRNA function and the evidence is compelling, suggesting shared mechanism(s) in the regulation of ASARs and Xist RNAs by RBPs that bind Cot1 sequences in these lncRNAs. This manuscript should be of interest to the noncoding RNA and chromatin biology communities.

eLife assessment

This valuable study provides insights into how the brain parses the syntactic structure of a spoken sentence. Convincing evidence is provided that distributive cortical networks are engaged for incremental parsing of a sentence, and neural activity recorded by MEG correlates with sentence structure measures extracted by a deep neural network language model, i.e., BERT. A contribution of the work is to use a deep neural network model to quantify how the mental representation of syntactic structure updates as a sentence unfolds in time.

eLife assessment

This study enhances our understanding of the relationship between cortico-hippocampal interactions and behavioral performance. Using an inter-areal coherence metric to gate trial initiation in real time, the authors provide solid evidence that links high hippocampal-prefrontal theta coherence to correct performance on spatial working memory and cue-guided decision-making tasks. Although reviewers agreed that the results do not demonstrate causality between hippocampal-prefrontal synchrony and behavioral performance, the findings are viewed as important given their potential implications for brain-machine interface applications in humans.

eLife assessment

This useful study, which systematically addresses off-target effects of a commonly used chemotherapy drug on bone and bone marrow cells and which therefore is of potential interest to a broad readership, presents evidence that reducing systemic inflammation induced by doxorubicin limits bone loss to some extent. Although the work does not inform in detail on the underlying mechanisms of doxorubicin action, the demonstration of the effect of systemic inflammation on bone loss is convincing. While not a new finding, the work sets the scene for additional genetic and pharmacologic experiments and a deeper analysis of the bone phenotype presented here, which should speak to the mechanisms involved in doxorubicin-induced bone loss and which may substantiate the clinical relevance of targeting inflammation in order to limit the negative impact of chemotherapies on bone quality.

eLife assessment

The results from this study, which investigates the mechanisms necessary for initiating tissue invagination using a cellular Potts modelling approach, suggests that apical constriction is not sufficient to drive the process by itself. The study highlights how choices inherent to modelling - such as permitting straight or curved cell edges - may affect the outcome of simulations and, consequently, their biophysical interpretation. Despite incomplete evidence supporting their major claims due to a rather coarse-grained exploration of the model, this work is useful for biophysicists investigating complex tissue deformation through computational frameworks.

eLife assessment

This important study reports the generation of genetic tools for manipulating several tissues at the same time in Drosophila. The authors provide convincing evidence that this allows for the generation of LexA and QF2 driver lines, which will be of great utility for understanding inter-organ communication.

eLife assessment

In this important manuscript, Abd El Hay and colleagues reveal a clear role of TRPV1 and TRPM2 receptors in warm temperature perception and present a technically unique experimental strategy to measure and analyze temperature preference behavior, which will have a lasting impact on the field. In addition to the behavioral data, which is strong, the study provides an analysis of cultured sensory neurons to controlled warmth stimuli - in this case, the evidence relating the activity of TRPM2 channels to the behavioral responses of animals is incomplete. Overall, the findings are of importance for neuroscientists, physiologists, and biophysicists, as there is still substantial discussion in the field regarding the contribution of TRP channels to different aspects of thermosensation.

eLife assessment

This work presents an important online platform designed to facilitate the exploration of genes and genetic pathways implicated in human aging.

The manuscript provides solid evidence that MotorNet is easy to use and can reproduce past results in the field, both at the neural and behavioural levels. Validation is limited to planar arm-like plants or point-masses, so future work exploring three-dimensional movements and other types of plants would strengthen the impact of the tool.

eLife assessment

The authors address the function of keratin 17 (K17), a marker of the most aggressive pancreatic ductal adenocarcinomas (PDACs). While this potentially useful study addresses a significant area of pancreatic cancer research, the lack of evidence demonstrating nuclear localization of K17 in human PDAC and the excessive reliance on a single cell line reduce the significance of the work. Moreover, the weak phenotypes of K17 phosphosite mutants provide incomplete support for the authors' mechanistic model.

eLife assessment

This potentially important paper addresses the question of how numerical information is represented in the human brain. Experimental findings are interpreted as providing evidence for a sensorimotor mechanism that involves channels, each tuned to a particular numerical range. While this is an interesting application of methodologies used to identify the presence of channels, the evidence supporting the claim that these have a sensorimotor basis is incomplete.

eLife assessment

In this manuscript, the authors present a wealth of fMRI data at both 3T and 7T to identify a scene-selective region of the intraparietal gyrus ("PIGS") that appears to have some responsivity to characteristics of ego-motion. In a series of experiments, they delineate the anatomical location of PIGS and functionally differentiate it from nearby V6 and OPA. Evidence for these important findings is solid, but further investigations as to the role of this region in processing ego-motion will be needed to confirm this conclusion.

eLife assessment

This valuable study showed convincing evidence that archerfishes can adapt their shooting behaviors to airflow perturbations.

eLife assessment

This useful study addresses the brain correlates underlying technical reasoning by a set of fMRI experiments and locates it to PF. If confirmed, this study provides an intriguing framework for our understanding of different types of problem-solving processes.

eLife assessment

This important study advances our understanding of the mechanisms of neuronal large dense-core vesicle (LDCV) secretion, which mediates neuropeptide and neurotrophin release. It describes a negative regulatory process involving the interaction of the Rab3-effector Rabphilin-3A with the SNARE fusion protein SNAP25, which limits LDCV secretion and neurite growth. The evidence in support of the authors' claims is solid overall, but some conclusions, e.g regarding the exact synaptic localization of Rabphilin-3A, its association with large dense-core vesicles, or the role of Rabphilin-3A-controlled neurotrophin signaling in neurite growth, are incompletely supported. This study will be of interest to the fields of cell biology, cellular neuroscience, and neuroendocrinology.

eLife assessment

This study provides valuable insights into understanding bone fragility in T2D patients through the use of human skeletal tissue, reinforcing previous pre-clinical studies or observational studies using serum samples that the Wnt signaling pathway may play a critical role in T2D-related bone impairment.

The authors provide solid evidence that any contribution of oligodendrocyte precursors to the developing cortex from the lateral ganglionic eminence is minimal in scope. The methods used support the conclusions, with some technical concerns that the authors can address with further experimentation. These are considered valuable additions to our understanding of the origins of oligodendrocytes in the forebrain during development.

eLife assessment

This useful study presents data regarding the presence of synaptic proteins in the extracellular vesicle pool present in the blood of Parkinson's patients and non-parkinson neurological outpatients, trying to correlate changes in such levels with the progression of Parkinson's symptoms. The results are semi-quantitative and preliminary, suggesting that these biomarkers could be used in the follow up of a specific group of Parkinson patients. The evidence is incomplete at this point, and more quantitative approaches are required to propose this correlation. The isolation of extracellular vesicles was appropriate as revealed by their sizes, but they are not exclusively from neuronal origin. The presented approach is not ready to be used in the clinical setting.

eLife assessment

This study unveils important mechanistic insights into postnatal lung development and bronchopulmonary dysplasia (BPD) pathology. Using two BPD models enhances our comprehension of the disease, utilizing compelling evidence from single-cell sequencing and flow cytometry, revealing a myofibroblast loss. Pharmacological and genetic approaches convincingly argue against the presumed increase in TGFb signaling causing alveolar simplification; instead, it appears to be a compensatory response. The identified weakness is the absence of validation in tissue, leaving the question unanswered regarding whether myofibroblast loss is due to a lack of myofibroblast proliferation or myofibroblast differentiation/specification.

With modifications, the paper should be of interest to those interested in T-cell development.

eLife assessment

This study characterizes the composition and immune diversity of the zebrafish kidney, the immune organ equivalent to human bone marrow, with convincing single-cell transcriptomic data of hematopoietic cells and immunocytes. The key findings suggest that zebrafish kidney is a secondary lymphatic organ, and that hematopoietic stem cells in zebrafish may exhibit trained immunity, which are the unique features of the fish immune system. This study provides new and valuable insights into the antiviral response in teleost fish, which will be of interest to biologists in general, and to immunologists and cancer researchers in particular.

This work describes a valuable new technique involving proximity labelling to identify Drosophila proteins modified by GlcNAcylation in subsets of cells in vivo. A solid set of experiments shows that several ribosomal proteins are modified in the fly mushroom body. Consistent with a role for GlcNAcylation of ribosomal proteins in control of memory related translational control, the authors show that perturbation of GlcNAc modification in KCs prevents efficient consolidation of long-term memory.

This important study outlines how the agr quorum sensing system in Staphylococcus aureus confers long-lived protection against oxidative stress, thereby linking bacterial metabolism to virulence in this pathogen. While the findings, which are supported by solid data, seem at first glance to contradict earlier findings that show increased fitness of agr mutants under oxidative stress, the core conclusions of the study are well-substantiated. The authors should, however, re-evaluate their interpretations related to the impact of agr inactivation on bacterial metabolic and redox status following oxidative stress. The topic of the paper holds broad relevance to microbiologists, especially those focusing on host-pathogen interactions and bacterial responses to ROS.

This important study follows up on previous work defining the anti-leukemic effects of a previously characterized cannabis extract on Notch-activated T cells and identifies several pathways that mediate its anti-cancer activity including the ER calcium and integrated stress response. The evidence is solid, but several concerns remain including the over reliance on a single cell line for the majority of the studies and lack of integration of the observations with existing literature

eLife assessment

Using state-of-the-art fate-mapping models and genetic and pharmacological targeting approaches, this study provides important findings on the distinct functions exerted by resident and recruited macrophages during cardiac healing after myocardial ischemia. Evidence supporting the conclusions are solid with the use of the FIRE mouse model in combination with fate-mapping to target fetal-derived macrophages. This study will be of interest for the macrophage biologists working in the heart but also in others tissues in the context of inflammation.

eLife assessment

The study presents important findings regarding a transcription-independent component of the early recovery of proteasome activity from a short pulse of proteasome inhibitor treatment, which has not been appreciated before and which is independent of the DDI2-NRF2 axis. While the evidence is in principle solid, with recapitulation in several cell line models, the proposed alternative underlying mechanism, namely regulation at the level of proteasome assembly, lacks experimental support, and at this point remain speculative.

eLife assessment

The authors build upon prior data implicating the secreted peptidoglycan hydrolase SagA produced by Enterococcus faecium in immunotherapy. Leveraging new strains with sagA deletion/complementation constructs, the investigators reveal that sagA is non-essential, with sagA deletion leading to a marked growth defect due to impaired cell division, and sagA being necessary for the immunogenic and anti-tumor effects of E. faecium. In aggregate, the study utilizes compelling methods to provide both fundamental new insights into E. faecium biology and host interactions and a proof-of-concept for identifying the bacterial effectors of immunotherapy response.

This study, which seeks to identify factors from the glial niche that support and maintain neural stem cells, unveils a novel role for ferritin in this process. Furthermore, the work shows that defects in larval brain development resulting from ferritin knockdown can be attributed to impaired Fe-S cluster activity and ATP production. These findings will be valuable to both oncologists and neurobiologists, though the supporting evidence is currently incomplete.

eLife assessment

This important work presents a new methodology for the statistical analysis of fiber photometry data, improving statistical power while avoiding the bias inherent in the choices that are necessarily made when summarizing photometry data. The reanalysis of two recent photometry data sets, the simulations, and the mathematical detail provide convincing evidence for the utility of the method and the main conclusions, however, the discussion of the re-analyzed data is incomplete and would be improved by a deeper consideration of the limitations of the original data. In addition, consideration of other data sets and photometry methodologies including non-linear analysis tools, as well as a discussion of the importance of the data normalization are needed.

eLife assessment

This manuscript presents a valuable, lightweight software package that aims to accelerate the implementation of experiment pipelines running on heterogeneous computer environments. The authors present solid evidence of the advantages of their chosen approach, including demonstrating the flexibility, ease of use, and practical utility of this new system. However, questions remain regarding the maturity of the project and its specific advantages in relation to existing widely adopted software packages.

eLife assessment

This important study investigated transcriptional profiles of midbrain dopamine neurons using single nucleus RNA (snRNA) sequencing. The authors found more nuanced subgroups of dopamine neurons than previous studies, and identified some genes that are preferentially expressed in subpopulations that are more vulnerable to neurochemical lesions using 6-hydroxydopamine (6OHDA). The results are convincing and provide critical information on the heterogeneity and vulnerability of dopamine neurons which will be a foundation for future studies.

eLife assessment

This work addresses the connectivity of giant excitatory neurons in a part of CA1 of the hippocampus. Recordings in rat brain slices provide new evidence that these cells excite bistratified and basket inhibitory neurons, and have weak inhibitory input from basket cells, as well as other findings. This circuitry gives these cells unique potential, making the work valuable, however the strength of the evidence is currently incomplete.

eLife assessment

In this important study, Xiong and colleagues studied PKA regulation in synaptic plasticity. They provide convincing evidence that dissociation of PKA catalytic subunits is essential for the proper function of the kinase. Experiments using a PKA regulatory-catalytic subunit fusion establish that dissociative activation is required for both structural long-term potentiation and basal priming of AMPA receptors.

eLife assessment

This useful manuscript reports on a new mouse model for LAMA2-MD, a rare but very severe congenital muscular dystrophy; the knockout mice were generated by removing exon3 in the Lama2 gene, which results in a frameshift in exon4 and a premature stop codon. These animals lack any laminin-alpha2 protein and confirm results from previous Lama2 knockout models. Additionally, this study includes transcriptomics data that might be a good resource for the field. However, the experimental evidence supporting the main claims of the manuscript is incomplete, citations of previous Lama2 null mice studies are lacking, and both data presentation and interpretation need improvement.

eLife assessment

This valuable study addresses one way in which animals identify predator-associated cues and respond in a manner that reflects the imminence of the potential threat. The report shows that, in mice, fresh saliva from a natural predator (cat) elicits a greater defensive response compared to old cat saliva and implicates the vomeronasal organ and ventromedial hypothalamus as part of a circuit that underlies this process. While the study has potential, the results are somewhat preliminary, and as such support for the primary conclusions is incomplete.

eLife assessment

This important study by 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 and suggest that VP responses represent values in a more abstract form while OT contains more odor information, potentially enhancing odor contrast. The reviewers found the results overall convincing although the nature of OT responses needs to be investigated further.

eLife assessment

This study addresses the role of FMRP in the migration of newborn neuroblasts in the postnatal brain. Through extensive and convincing analysis of living imaging videos, the authors showed that neurons with FMRP deletion migrate aberrantly and exhibit defects in nucleokinesis and centrokinesis. The study presents a valuable finding on the mechanism of neuroblast migration in the postnatal brain.

This is a fundamental resource of snRNA-seq and and chromatin accessibility data from human aortic endothelial cells (ECs), treated with relevant perturbations such as IL1b, TGFB2, or si-EGR. The authors show that ECs can be categorized by distinct subpopulations of differing plasticity. The support for the existence of these subpopulations is compelling, supported also by three publicly available scRNA-seq datasets, and differential enrichment of coronary artery disease associated SNPs in open chromatin in these subpopulations.

eLife assessment

This valuable paper examines the role of the WRNIP1 AAA+ ATPase in regulating R-loop formation, which induces a conflict with active replication forks and transcription. The authors provide convincing evidence to support a role of the ubiquitin-binding UBZ domain of WRNIP1 in R-loop suppression generated by this conflict. The work is of interest to researchers who work on genome stability/instability.

eLife assessment

Large scale cell movements occur during gastrulation in vertebrate embryos but their role in this major morphogenetic transition in formation of the body plan is poorly understood. Using the chick embryo model system, this study makes important advances using elegant methods to show that extension of the primitive streak during gastrulation, occurring through cell proliferation, polarisation and intercalation, and large-scale polonaise cell movements, can be uncoupled. Although the driving mechanism and precise role of these movements remains a mystery, the study provides convincing evidence for the uncoupling through independent approaches, the most creative of which are the effects shown after induction of a supernumerary primitive streak.

The work will be of broad interest to scientists working in the field of Hippo signaling and cancer biology.

eLife assessment

This important study identifies a role for triglycerides and lipid droplets in spermatogenesis, with data supporting relevance of this finding across phyla. The work shows with convincing data that a triglyceride lipase is required cell-autonomously for germline differentiation into meiotic stages and haploid spermatids and that an increase in triglycerides is detrimental to spermatogenesis. This paper would be of interest to developmental and cell biologists working on gametogenesis.

eLife assessment

This study presents valuable empirical work and simulations that are relevant for the evolution of genetic load linked to self-incompatibility alleles in Arabidopsis. The evidence supporting the findings is solid but could be improved by a more detailed quantitative assessment of the impacts of deleterious alleles and their dominance. The simulation results are somewhat incomplete, as details of the approach and code do not appear to be available, but this could be easily remedied. The work will be of relevance to geneticists interested in the evolution of allelic diversity in similar systems.

eLife assessment

This valuable study provides the detailed molecular mechanism of how OGT, an O-GlcNac transferase, promotes cancer progression. Using loss-of-function OGT models, the authors demonstrated that OGT cleaves HCF-1, a guardian of genomic stability. These solid findings can lead to some potential approaches to modulate anti-tumor immunity by targeting this process.

eLife assessment

This manuscript provides useful information about the lipid metabolite 15d-PGJ2 as a potential regulator of myoblast senescence. The authors provide experimental evidence that 15d-PGJ2 inhibits myoblast proliferation and differentiation by binding and regulating HRas. However, the manuscript is incomplete in its current form, as it lacks robust support from the data regarding the main conclusions related to senescence and technical concerns related to the senescence models used in this study.
