      This valuable study combines proteomics and a mouse model to reveal the importance of iron uptake in bacterial therapy for cancer. The evidence presented is convincing. Notably, the authors showed upregulation of iron uptake of bacteria significantly inhibits tumor growth in vivo. This paper will be of interest to a broad audience including researchers in cancer biology, cell biology, and microbiology.

    1. eLife assessment

      This useful manuscript challenges the utility of current paradigms for estimating brain-age with magnetic resonance imaging measures, but presents inadequate evidence to support the suggestion that an alternative approach focused on predicting cognition is more useful. The paper would benefit from a clearer explication of the methods and a more critical evaluation of the conceptual basis of the different models. This work will be of interest to researchers working on brain-age and related models.

    1. eLife assessment

      This valuable study introduces an innovative method for measuring interocular suppression depth, which implicates mechanisms underlying subconscious visual processing. The evidence is solid in suggesting that the new method yields provocative uniform suppression depth results across image categories that differ from conventional bCFS threshold. It 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 important 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 convincing, although the experimental design makes it difficult to definitively distinguish aversive valence from stimulus salience in this dopamine projection. This work will be of interest to neuroscientists working on neuromodulatory systems, cortical function and decision making.

    1. eLife assessment

      This magnetoencephalography study reports important new findings regarding the nature of memory reactivation during cued recall. It replicates previous work showing that such reactivation can be sequential or clustered, with sequential reactivation being more prevalent in low performers. It adds convincing evidence, even though based on limited amounts of data, that high memory performers tend to show simultaneous (i.e., clustered) reactivation, varying in strength with item distance in the learned graph structure. The study will be of interest to scientists studying memory replay.

    1. eLife assessment

      This useful study reports the behavioural and physiological effects of the longitudinal activation of neurons associated with negative experiences. The main claims of the paper are supported by solid experimental evidence, but the specificity of the long-term manipulation requires additional validation. This study will be of interest to neuroscientists working on memory.

    1. eLife assessment

      This important work provides insights into the neural mechanisms regulating specific parental behaviors. By identifying a key role for oxytocin synthesizing cells in the paraventricular nucleus of the hypothalamus and their projections to the medial prefrontal cortex in promoting pup care and inhibiting infanticide, the study advances our understanding of the neurobiological basis of these contrasting behaviors in male and female mandarin voles. The evidence supporting the authors' conclusions is solid but lacks some critical methodological detail. The work should be of interest to researchers studying neuropeptide control of social behaviors in the brain.

    1. eLife assessment

      This method paper proposes a valuable Oscillation Component Analysis (OCA) approach, in analogy to Independent Component Analysis (ICA), in which source separation is achieved through biophysically inspired generative modeling of neural oscillations. The empirical evidence justifying the approach's advantage is incomplete. This work will be of interest to cognitive neuroscience, neural oscillation, and MEG/EEG.

    1. eLife assessment

      The manuscript looks at how dysregulated purine metabolism in mutants for the Aprt gene impacts survival, motor and sleep behavior in the fruit fly. Interestingly, although several deficits arise from dopaminergic neurons, dopamine levels are increased in Aprt mutants. Instead the biochemical change responsible for Aprt mutant neurobehavioural phenotypes appears to be a reduction in levels of adenosine. This valuable study suggests that Drosophila Aprt mutants may serve as a model for understanding Lesch-Nyhan Disease (LND), caused by mutations in the human HPRT1 gene, and may also potentially serve as a model to screen for drugs for the neurobehavioural deficits observed in LND. The strength of evidence is solid.

    1. eLife assessment

      This important study reports the use of a surveillance approach in identifying emerging diseases, monitoring disease trends, and informing evidence-based interventions in the control and prevention of livestock abortions, as it relates to their public health implications. The data support the convincing finding that abortion incidence is higher during the dry season, and occurs more in cross-bred and exotic livestock breeds. Aetiological and epidemiological data can be generated through established protocols for sample collection and laboratory diagnosis. These findings are of potential interest to the fields of veterinary medicine, public health, and epidemiology.

    1. eLife assessment

      This study is of potential interest to readers in human genetics and quantitative genetics, as it presents a new method for homozygosity mapping in population-scale datasets, based on an innovative computational algorithm that efficiently identifies runs-of-homozygosity (ROH) segments shared by many individuals. Although the method is innovative and has the potential to be broadly useful, its power and limitations have not yet been adequately evaluated. The application of this new method to the UK Biobank dataset identifies several interesting associations, but it remains currently unclear under what conditions the new approach can provide additional power over existing genome-wide association study methods.

    1. eLife assessment

      The authors perform voltage imaging of CA1 pyramidal cells in head-fixed mice running on a track while local field potentials (LFPs) are recorded. They suggest that synchronous ensembles of neurons are differentially associated with different types of LFP patterns, namely theta and ripples. However, evidence for the potentially useful findings is currently incomplete due to major weaknesses in the experimental and analytical approach.

    1. eLife assessment

      This important study advances our understanding of how past and future information is jointly considered in visual working memory by studying gaze biases in a memory task that dissociates the locations during encoding and memory tests. The evidence supporting the conclusions is convincing, with state-of-the-art gaze analyses that build on a recent series of experiments introduced by the authors. This work will be of broad interest to vision scientists interested in the interplay of vision, eye movements, and memory.

    1. eLife assessment

      This important study provides previously unappreciated insights into the functions of protist eIF4E 5'mRNA cap-binding protein family members, thereby contributing to a better understanding of translation regulation in these organisms. The authors provide solid evidence to support the major conclusions of the article. However, the study may further benefit from establishing whether all of the eIF4E family members are indeed involved in translation and more direct evidence for the selectivity of their binding.

    1. eLife assessment

      This study uses ex vivo live imaging of the uterus, uterotubal junction, and oviduct post-mating to test the role of the sperm hook in the house mouse (Mus musculus) in sperm movement which could be interesting to evolutionary biologists. The work is useful as their live imaging revealed sperm behaviors in the female tract that have not been previously reported. However, the strength of evidence is incomplete since the limited quantification of the data is insufficient and the extensive speculation on the functions of these sperm behaviors is not supported by sufficient experimental evidence to support their conclusions.

    1. eLife assessment

      This study provides valuable information on the mechanism of PepT2 through enhanced-sampling molecular dynamics, backed by cell-based assays, highlighting the importance of protonation of selected residues for the function of a proton-coupled oligopeptide transporter (hsPepT2). The molecular dynamics approaches are convincing, but with limitations that could be addressed in the manuscript, including lack of incorporation of a protonation coordinate in the free energy landscape, possibility of protonation of the substrate, errors with the chosen constant pH MD method for membrane proteins, dismissal of hysteresis emerging from the MEMENTO method, and the likelihood of other residues being affected by peptide binding. Some changes to the presentation could be considered, including a better description of pKa calculations and the inclusion of error bars in all PMFs. Overall, the findings will appeal to structural biologists, biochemists, and biophysicists studying membrane transporters.

    1. eLife assessment

      The manuscript presents a useful model for the field of endosome maturation, providing perspective on the role of the deubiquitinating enzyme UPS-50/USP8 in the process. The evidence presented in the paper is clear, incorporating well-designed experiments that suggest the dual actions of UPS-50 and USP8 in the conversion of early endosomes into late endosomes. Overall, the work is solid and centers on an intriguing subject.

    1. eLife assessment

      This important study reports the formation of a new organelle, called giant unilocular vacuole (GUVac), in mammary epithelial cells through a macropinocytosis-like process. The evidence supporting conclusions is solid, using state-of-the-art cell biology techniques. This work will be of interest to cell biologists and contribute to the understanding of cell survival mechanisms against anoikis.

    1. eLife assessment

      In this valuable study, Kumar et al., provide evidence suggesting that the p130Cas drives the formation of condensates that sprout from focal adhesions to cytoplasm and suppress translation. Pending further substantiation, this study was found to be likely to provide previously unappreciated insights into the mechanisms linking focal adhesions to the regulation of protein synthesis and was thus considered to be of broad general interest. However, the evidence supporting the proposed model was incomplete; additional evidence is warranted to substantiate the relationship between p130Cas condensates and mRNA translation and establish corresponding functional consequences.

    1. eLife assessment

      This fundamental study offers new structural insights into the form and functions of the ribosome-translocon complex. Through a combination of in vitro translation, cryoEM imaging, and comprehensive AlphaFold comparative modeling, the authors offer convincing support for the lateral gate model of co-translational ER protein biogenesis, including the location of RAMP4 near the Sec61 lateral gate and the plausible role of helix 59 of the 28S ribosomal RNA as a determinant of the positive-inside rule. While the reviewers identified minor limitations, such as the need to validate RAMP4 presence with orthogonal measures, these results will be broadly impactful.

    1. eLife assessment

      This study provides a useful strategy for treating mouse cutaneous squamous cell carcinoma (mCSCC) with serum derived from mCSCC-exposed mice. The exploration of serum-derived antibodies as a potential therapy for curing cancer is particularly promising but the study provides inadequate evidence for specific effects of mCSCC-binding serum antibodies. This study will be of interest to scientists seeking a novel immunotherapic strategy in cancer therapy.

    1. eLife assessment

      This work describes a novel affinity interactomics approach that allows investigators to identify networks of protein-protein interactions in cells. The important findings presented here describe the application of this technique to the SH3 domain of the membrane remodeling Bridging Integrator 1 (BIN1), the truncation of which leads to centronuclear myopathy. The authors present solid evidence that BIN1 SH3 engages with an unexpectedly high number of cellular proteins, many of which are linked to skeletal muscle disease, and evidence is presented to suggest that BIN1 may play a role in mitosis creating the potential for new avenues in drug development efforts. Some of the findings, however, remain rather preliminary, lack sufficient replicates and may require additional experiments to definitively support the conclusions.

    1. eLife assessment

      This manuscript presents valuable findings on the identification of epigenetically mediated control for the recognition of dihydropyrimidine dehydrogenase (DPYD) gene expression that is linked with cancer treatment resistance using 5-fluorouracil. The evidence is compelling, supported by data from patient-derived specimens and direct assessment of 5-fluorouracil sensitivity, which provides confidence in the proposed mechanisms. The model is additionally supported by genome data from a population with high "compromised allele frequency". This work will interest those studying drug resistance in cancer therapy.

    1. eLife assessment

      This study presents valuable new structures of a carbamylation-mimetic K125E mutant of the Cx26 gap junction channel uncovering the cytoplasmic loop structure and information about the closed state of the channel. The cryo-EM maps are in high quality and serve as strong foundations for dissecting the gating mechanism by CO2, providing convincing evidence in support of a mechanism where CO2-mediated carbamylation of Lys125 shifts the conformational equilibrium towards a state where the N-terminus occludes the pore of the channel. This information will be of interest to biochemists, cell biologists and biophysicists interested in the function of gap-junction channels in health and disease.

    1. eLife assessment

      This is a valuable 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 used to predict how muscles function for stability but also how they can be injured, and which tend to be predicted poorly by classic Hill-type models. The evidence presented to support the model is solid, since it outperforms Hill-type models in a variety of conditions. Although the combination of phenomenological and mechanistic aspects of the model may sometimes make it challenging to interpret the output, the work will be of interest to those developing realistic models of the stability and control of movement in humans or other animals.

    1. eLife assessment

      The study presents valuable findings where two-domain thermodynamic model for TetR accurately predicts in vivo phenotype changes brought about as a result of various mutations. The evidence provided is compelling and features the first innovative observations with a computational model that captures the structural behavior, much more than the current single-domain models.

    1. eLife assessment

      This fundamental study for the first time defines genetically the role of the Clock gene in basal metazoa, using the cnidarian Nematostella vectensis. With convincing evidence, the study provides insight into the early evolution of circadian clocks. Clock in this species is important for daily rhythms under constant conditions, but not under a rhythmic light/dark cycle, suggesting that the major role of the circadian oscillator in this species could be a stabilizing function under non-rhythmic environmental conditions.

    1. eLife assessment

      BMP signaling plays a vital role in skeletal tissues, and the importance of its role in microtia prevention is novel and promising. This important study sheds light on the role of BMP signaling in preventing microtia in the ear, with solid data broadly supporting the claims of the authors.

    1. eLife assessment

      This study presents useful findings on an unresolved question of cerebellar physiology: Do synapses between Purkinje cells and granule cells, made by the ascending part of the granule cells' axon, have different properties than those made by parallel fibers? The authors conducted patch-clamp recordings on rat cerebellar slices and found a new type of plasticity in the synapses of the ascending part of granule cell axons. While the finding may contribute to a better understanding of cerebellar function, the results are still incomplete because the shift in the baseline recording may have influenced the readout of long-term plasticity.

    1. eLife assessment

      This paper presents a valuable automated method to track individual mammalian cells as they progress through the cell cycle using the FUCCI system. The authors have developed a technique for analyzing cells that grow in suspension and used their method to look at different tumor cell lines that grow in suspension and determine the effect of drugs that directly affect the cell cycle. They show solid evidence that the method can be applied to both adherent and non-adherent cell lines. This paper will be of interest to cell biologists investigating cell cycle effects.

    1. eLife assessment

      This work uses an interdisciplinary approach combining microfluidics, structural biology, and genetic analyses to provide important findings that show that pathogenic enteric bacteria exhibit taxis toward human serum. The data are compelling and show that the behavior utilizes the bacterial chemotaxis system and the chemoreceptor Tsr, which senses the amino acid L-serine. The work provides an ecological context for the role of serine as a bacterial chemoattractant and could have clinical implications for bacterial bloodstream invasion during episodes of gastrointestinal bleeding.

    1. eLife assessment

      This study reports useful data suggesting the critical roles of two ancient proteins, XAP5 and XAP5L, in controlling the transcriptional program of ciliogenesis during mouse spermatogenesis. However, this study is considered incomplete because the data only partially support the conclusion. This work will be of interest to biomedical researchers who work on ciliogenesis and reproduction.

    1. eLife assessment

      This important study by Lu et al aimed to determine the key factors of T cell responses associated with durable antibody responses following the initial two shots of COVID-19 mRNA vaccinations. By comparing the SARS-CoV-2 spike protein (S)-specific T cell subsets between "Ab sustainers" and "Ab decliners" that were present post-vaccination, the authors concluded that S-specific CD4+ T cells in "Ab sustainers" were enriched with Tfh cells. There is solid evidence as the authors applied multiple methods and approaches to address the key questions, and the presented data are robust.

    1. eLife assessment

      In this paper, the male sex-lethal (MSL) complex of proteins and RNA is studied through a domain analysis of one of its components, MSL1, and its interaction with others. While these results could be useful to researchers in the field, several studies have shown that the view that the MSL complex mediates dosage compensation is no longer considered tenable. Since there are many ways to alter viability, claims based on sex-specific viability as a reflection of dosage compensation should be viewed with much caution, and the evidence is currently considered inadequate to support the claims.

    1. eLife assessment

      This study characterizes how a point mutation in the TALK-1 potassium channel, encoded by the KCNK16 gene, causes MODY diabetes. The mutation, L114P, causes a gain-of-function to increase K+ currents and inhibit glucose-stimulated insulin secretion. Increased glucagon likely results from paracrine effects in the islets. The data are convincing and the work will be valuable for understanding islet function.

    1. eLife assessment

      This important study demonstrated that ablation of astrocytes in the lumbar spinal cord not only reduced neuropathic pain but also caused microglia activation. The findings presented add considerable value to the current understanding of the role of astrocyte elimination in neuropathic pain, offering convincing evidence that supports existing hypotheses and insights into the interactions between astrocytes and microglial cells, likely through IFN-mediated mechanisms. This study may also offer a new therapeutic strategy for the treatment of debilitating neuropathic pain in patients with SCI.

    1. eLife assessment

      This study presents a valuable finding that the blood-brain barrier functionality changes with age and differs between males and females. The analysis is solid, comprising a large and racially diverse dataset, and utilizes a contrast-agent-free MRI method. Since limited work has been done in the MRI field on the blood-brain barrier using this method, this study is of great interest to neuroimaging researchers and clinicians.

    1. eLife assessment

      This work substantially advances our understanding of pharmacological inhibition of SWI/SNF as a therapeutic approach for cancer. The study is well-written and provides compelling evidence, including comprehensive datasets, compound screens, gene expression analysis, epigenetics, as well as animal studies. This study provides a fundamental advance for the uveal melanoma research field that might be exploited to target this deadly cancer and more generally for targeting transcriptional dependency in cancers.

    1. eLife assessment

      In this useful study, the authors report the efficacy, hematological effects, and inflammatory response of the BPaL regimen (containing bedaquiline, pretomanid, and linezolid) compared to a variation in which Linezolid is replaced with the preclinical development candidate spectinamide 1599, administered by inhalation in tuberculosis-infected mice. The authors provide convincing evidence that supports the replacement of Linezolid in the current standard of care for drug-resistant tuberculosis. However, a limitation of the work is the lack of control experiments with bedaquiline and pretomanid only, to further dissect the relevant contributions of linezolid and spectinamide in efficacy and adverse effects. Although the manuscript is well written overall, a re-formulation of some of the stated hypotheses and conclusions, as well as the addition of text to contextualize translatability, would improve its value.

    1. eLife assessment

      This important study identifies the anti-inflammatory function of PEGylated PDZ peptides that are derived from the ZO-1 protein. Results from cellular and in vivo experiments tracking key inflammatory markers are compelling. Although the mechanism of action remains largely unknown, this study provides a proof of concept for developing novel strategies against acute inflammatory conditions such as sepsis.

    1. eLife assessment

      This useful study investigates the impact of disrupting the interaction of RAS with the PI3K subunit p110α in macrophage function in vitro and inflammatory responses in vivo. Solid data overall supports a role for RAS-p110α signalling in regulating macrophage activity and so inflammation, however for many of the readouts presented the magnitude of the phenotype is not particularly pronounced. Further analysis would be required to substantiate the claims that RAS-p110α signalling plays a key role in macrophage function. Of note, the molecular mechanisms of how exactly p110α regulating the functions in macrophage have not yet been established.

    1. eLife assessment

      The study is useful by attempting to present a new approach of combining two measurements (pHLA binding and pHLA-TCR binding) in order to refine predictions of which patient mutations are likely presented to and recognized by the immune system, but the evidence is incomplete. Whereas the novel methodology proposed is compelling, this article lacks a detailed explanation of the chosen model. The experimental validation confirming the computational predictions with actual immune responses is limited due to sample constraints.

    1. eLife assessment

      The manuscript by Jingsong Zhou and colleagues uncovers why the extraocular muscles (EOMs) are preserved while other muscles undergo degenerative changes in amyotrophic lateral sclerosis (ALS). In this work, the authors have used a mouse model of familial ALS that carries a G93A mutation in the Sod1 gene to demonstrate that NaBu treatment partially restores the integrity of NMJ in the limb and diaphragm muscles of G93A mice. The findings of the study offer important information that EOMs are spared in ALS because they produce protective factors for the NMJ and, more specifically, factors secreted by EOM-derived satellite cells. While most of the experimental approaches are convincing, the use of sodium butyrate (NaBu) in this study needs further investigation, as NaBu might have a variety of biological effects. Overall, this work may help develop future therapeutic interventions for patients with ALS.

    1. eLife assessment

      This manuscript reports important data on the stability of nucleosomes with dsDNA substrates containing defined mismatches at three defined nucleosomal positions. Compelling evidence obtained by single-molecule FRET experiments shows that certain mismatches lead to more stable nucleosomes likely because mismatches kink to enhance DNA flexibility leading to higher nucleosome stability. The biological significance and implications of the findings remain unclear.

    1. eLife assessment

      This study presents important insights on the impact of SARS-CoV-2 variants on the binding and neutralization of a small library of nanobodies. The authors should be applauded for their comprehensive in vitro and in silico analyses of nanobody targeting of SARS-CoV-2 variants. The evidence supporting the claims of the authors is now convincing. This work will be of great interest to researchers in the fields of antibody/nanobody engineering and SARS-CoV-2 therapeutics.

    1. eLife assessment

      The fundamental study by Galicia C. et al. captured the GTP-bound active structure of CtRoco, a homolog of human LRRK2, using conformation-specific nanobodies. This convincing body of work reports the first structure of a GTP-bound ROCO protein, illustrating how GTP facilitates the dimer-to-monomer transition of CtRoco and functional activation.

    1. eLife assessment

      This is an important study that investigates how neural networks can learn to stochastically replay presented sequences of activity according to learned transition probabilities. The authors use error-based excitatory plasticity to minimize the difference between internally predicted activity and stimulus-driven activity, and inhibitory plasticity to maintain E-I balance. The approach is solid but the choice of learning rules and parameters is not always always justified, lacking a formal derivation and concrete experimental predictions.

    1. eLife assessment

      This valuable study delineates the cellular contributions of BMP signaling in liver development and function. The findings are convincing, and the study employs state-of-the-art molecular, genetic, and cellular approaches to demonstrate that hepatic stellate cells play a central role in liver health by mediating cell-to-cell crosstalk via the production of specific BMP proteins. This study will be of interest to scientists interested in developmental biology and organ physiology.

    1. eLife assessment

      This study assessed antibody levels, which are indicative of protection, resulting from both COVID-19 vaccination and natural infection in a representative sample of the Canadian population. The work provides solid evidence that Individuals who received a booster vaccination and had a prior infection had the highest antibody levels, particularly when either the vaccination or natural infection had occurred within the past six months. These findings are of fundamental importance in supporting the value of booster vaccination in populations vulnerable to severe COVID-19.

    1. eLife assessment

      This study presents an important finding that Obox4 and Dux act redundantly in regulating zygotic genome activation in mice. The evidence supporting the claims of the authors is solid. The work will be of interest to researchers interested in early embryo development and epigenetic reprogramming.

    1. eLife assessment

      This important study presents a detailed characterization of two distinct cellular morphologies of haematopoietic stem cells undergoing endothelial to haematopoietic transition in zebrafish. It brings new information on how regulation of apico-basal polarity influences cellular behaviour, shape, and interaction with neighbouring cells. The evidence supporting the existence of these two distinct morphologies is convincing, using state-of-the-art confocal microscopy and image analysis of 2D-cartography.

    1. eLife assessment

      This carefully executed study provides a comparison of the chemical composition of mouse urine across strain and sex with the responses of vomeronasal sensory neurons, which are responsible for detecting chemical social cues. While the authors did not examine all molecular classes found in mouse urine or directly test whether the urinary volatile chemicals that vary with sex and strain are effective vomeronasal neuron ligands, solid data are provided that will be of significant interest to those studying chemical communication in rodents. This work should provide a valuable foundation for future research that will determine which molecules drive sex- and strain-specific vomeronasal responses.

    1. eLife assessment

      This study is focused on the question of how Nrp1 contributes to the regulation of vascular permeability and whether or why there are differences between different vascular beds. The scientific concept of this paper suggests a possible role of Nrp1 on perivascular cells as a participant in the regulation of vascular permeability. This concept is interesting and potentially useful. However, the methodology and quantitative analysis are currently inadequate to fully support the claims.

    1. eLife assessment

      This important study uses cellular automata and evolution algorithms to offer an alternative to long-range signalling models of developmental patterning. The computational evidence that local rules suffice to produce a robust and global pattern is convincing. With some additional insights that connect the theoretical findings back to real biological examples, this work could be of interest to the broad community of developmental and systems biologists.

    1. eLife assessment

      This study presents valuable data on the antigenic properties of neuraminidase proteins of human A/H3N2 influenza viruses sampled between 2009 and 2017. The antigenic properties are found to be generally concordant with genetic groups. Compared to a previous version, additional analyses have strengthened the work, with solid evidence supporting the claims of the authors.

    1. eLife assessment

      This study presents an important finding that implicates a rhodopsin gene duplication in the progression of autosomal dominant retinitis pigmentosa in patients. The authors utilize a retinal organoid model to demonstrate a similar disease phenotype and suggest defects can be ameliorated by using photoregulin. The data supporting the conclusions are solid, but there are some concerns regarding the strength of the phenotype in retinal organoids. This work will be of broad interest to vision researchers.

    1. eLife assessment

      This important work examines the potential utility of socio-emotional and socio-cognitive mental training on hippocampal subfield structure and function, and cortisol levels. The authors provide convincing evidence that CA1-3 volume is sensitive to socio-emotional training, with changes related to function plasticity and cortisol levels. Further, the authors provide evidence of change across all subfields and training modules related to stress.

    1. eLife assessment

      This manuscript describes a potentially important theoretical framework to link predictive coding, error-based learning, and neuronal dynamics. The provided evidence is solid, but some details would benefit from additional clarification. The exposition of the manuscript is targeted for a specialist audience.

    1. eLife assessment

      This study presents a new and important theoretical account of spatial representational drift in the hippocampus. The evidence supporting the claims is convincing, with a clear and accessible explanation of the phenomenon. Overall, this study will likely attract researchers exploring learning and representation in both biological and artificial neural networks.

    1. eLife assessment

      This important study utilizes a viral-mediated short hairpin RNA (shRNA) approach to investigate in a novel way the role of the wild-type PHOX2B transcription factor expressed in critical chemosensory neurons in the brainstem retrotrapezoid nucleus (RTN) region for maintaining normal CO2 chemoreflex control of breathing in adult rats. The convincing results show blunted ventilation during elevated inhaled CO2 (hypercapnia) with knockdown of PHOX2B, accompanied by a reduced expression of Gpr4 and Task2 mRNA for the proposed RTN neuron proton sensor proteins GPR4 and TASK2. These results indicate that maintained expression of wild-type PHOX2B affects respiratory control in adult animals, complementing previous studies showing that PHOX2B-expressing RTN neurons may be critical for chemosensory control throughout the lifespan, and with implications for neurological disorders involving the RTN, which will be of interest to neuroscientists studying respiratory neurobiology as well as the neurodevelopmental control of motor behavior.

    1. eLife assessment

      This is a binocular rivalry study that uses ECG to present visual stimuli pulsing in line with cardiac events, to examine whether systole-entrained stimuli (i.e. presented during the period where the heart has contracted) are suppressed within visual awareness. Arguably out of line with this idea, the dominance durations were increased for systole-entrained stimuli. The manuscript addresses an important, precisely defined, and theoretically well-motivated question using sophisticated experimental and statistical methods. The interpretation of these results is not straightforward, however, such that they currently only provide incomplete support for the claims.

    1. eLife assessment

      Using in vitro and in vivo experiments, the authors show that astrocytes swell after inhibition of aquaporin 4 (AQP4) with TGN-020, which is indicative of tonic water efflux from these cells under physiological conditions. Though potentially valuable, the study is currently incomplete due to possible off-target effects of TGN-020, limited mechanistic information underlying the detected effects, and potential limitations of some of the adopted experimental techniques. These findings can be especially relevant for cortical spreading depression in ischemic stroke or seizure and to get a comprehensive understanding of neuron-astrocyte interactions.

    1. eLife assessment

      This fundamental work unravels how female Drosophila can assess their social context via chemosensory cues and modulate the sperm storage process after copulation accordingly. A convincing set of rigorous experiments uncovers specific pheromones that influence the excitability of the female brain receptivity circuit and their propensity to discard inseminate from a mating. This insight into neuronal mechanisms of sexual behavior plasticity is of general interest to scientists working in the fields of animal behavior, neuroscience, evolution, and sexual selection, as well as insect chemosensation and reproduction.

    1. eLife assessment

      This study presents valuable findings relevant to research on olfactory neurogenesis and long-term adaptation. The evidence, at this stage, is incomplete. First, the effects described could, in part, also be attributed to "downregulation" of OR subtype-specific neurogenesis upon sensory deprivation, instead of selectively increased neurogenesis. Second, additional control experiments would be needed to support the main claims and rule out alternative explanations.

    1. eLife assessment

      This is an important computational study that applies the machine learning method of bilinear modeling to the problem of relating gene expression to connectivity. Specifically, the author attempts to use transcriptomic data from mouse retinal neurons to predict their known connectivity with promising results. On revision, the approach was tested against a second data set from C. Elegans. A limited number of genes studied in this second dataset may have resulted in performance that matched but did not exceed prior models, however, taken together, the results were felt to provide solid evidence for the value of the approach.

    1. eLife assessment

      This study presents a valuable dataset regarding chromatin remodeling by the BAF complex in the context of meiotic sex chromosome inactivation. Solid data generally support the conclusions, although there is room for improvement. This work will be of interest to researchers working on chromatin and reproductive biology.

    1. eLife assessment

      This important study links the activity of polymerase III to the regulation of virulence gene expression in the deadliest malaria parasite, Plasmodium falciparum. It identifies Maf1 as a Pol III inhibitor that enables the parasite to respond to external stimuli such as magnesium chloride plasma levels by downregulating Pol III-transcribed ruf6 genes and subsequently regulated var genes. While the evidence presented is generally convincing, some of the results are incomplete, and the mechanistic link between external signals and Maf1 activation remains unknown.

      The OpuA Type I ABC importer uses two substrate binding domains to capture extracellular glycine betaine and present the substrate to the transmembrane domain for subsequent transport and correction of internal dehydration. This study presents valuable findings addressing the question of whether the two substrate binding domains of OpuA dock and physically interact in a salt-dependent manner. The single-molecule fluorescence resonance energy transfer and cryogenic electron microscopy data that are presented provide convincing support for the existence of a transient interaction between the substrate binding domains that depends on ionic strength, laying a foundation for future studies exploring how this interaction is involved in the overall transport mechanism.

    1. eLife assessment

      This important paper reveals that one of the major roles of the WDR5 WIN site is to promote ribosome synthesis, and that by attacking the WIN site with inhibitors ribosome attrition occurs creating new vulnerabilities that can be therapeutically exploited. This deficiency of ribosomal proteins also provokes the p53 response. The data from a variety of approaches is generally very convincing, and together buttresses the authors' conclusions and interpretations quite nicely; overall, this paper will provide a justification for pre-clinical and translational studies of WDR5 interaction site inhibitors.

      This useful work describes a novel microscopy-based method to correlate the degree of pigmentation with the gene expression profile of human-induced pluripotent stem cell-derived Retinal Pigmented Epithelial (iPSC-RPE) cells at the single cell level. The presented evidence is solid in showing that there is heterogeneous gene expression in iPSC-derived RPE cells, and there is no significant correlation with the pigmentation. By analyzing the expression of some genes related to function, lysosomal- and complement-related pathways were partially enriched in darker cells. This methodology can be used by other researchers interested in analyzing gene expression related to microscopic images.

    1. eLife assessment

      This useful study reports that a week or more of hypoxia exposure in mice increases erythropoiesis and decreases the number of iron-recycling macrophages in the spleen, compromising their capacity for red blood cell phagocytosis – reflected by increased mature erythrocyte retention in the spleen. Compared to an earlier version, the study has been strengthened with mouse experiments under hypobaric hypoxia and complemented by extensive ex vivo analyses. Unfortunately, while some of the evidence is solid, the work as it currently stands only incompletely supports the authors' hypotheses. While the study would benefit from additional experiments that more directly buttress the central claims, it should be of interest to the fields of hemopoiesis and bone marrow biology and possibly also blood cancer.

    1. eLife assessment

      This is an important study on changes in newborns' neural abilities to distinguish auditory signals at 37 weeks of gestation. The evidence of change in neural discrimination as a function of gestational age is convincing, but further analysis of the acoustic signals and description of the infants' language environment would strengthen the interpretation of the results. The work contributes to the field of neurodevelopment and suggests potential clinical applications in neurodevelopmental disorders.

    1. eLife assessment

    1. eLife assessment

      This study shows compelling evidence that the less common D-serine stereoisomer is transported in the kidney by the neutral amino acid transporter ASCT2 and that it is a non-canonical substrate for sodium-coupled monocarboxylate transporter SMCTs. With a multi-hierarchical approach, this important study further shows that Ischemia-Reperfusion Injury in the kidney causes a specific increment in renal reabsorption carried out, in part, by ASCT2.

    1. eLife assessment

      This valuable study further discloses the function of LRRK2 in BDNF-dependent synaptic processes in identifying postsynaptic actin cytoskeleton as a convergent site of LRRK2 pathophysiological activity. Multiple approaches in different cellular models provide mostly solid (but at times preliminary) evidence to support (many) of the conclusions, overall consistent with bioinformatics analyses covering previously published work. While an exciting start that should be pursued, examples are suggested by reviewers to add in additional experimentation to better support the expansive interpretation. The identification of mechanisms of LRRK2 action at the synapse is considered highly significant, as better knowledge in this regard may provide insight into why dopaminergic cells die with over-active LRRK2.

    1. eLife assessment

      This is a valuable study of the spatial organization of innate granulomas following Chromobacterium violaceum infection and the expression of CC and CXC chemokines in the granuloma at several time points following infection. There is a wealth of information to be gained from this study. However, the analysis of these granulomas is incomplete, with room for orthogonal validation of some of the key findings with additional animals (using ISH or IHC), in addition to a more quantitative analysis of some of the currently more qualitative conclusions.

    1. eLife assessment

      This study presents a valuable finding on the association between DUX4 expression with features of immune evasion in human tissue and clinical outcomes in patients with advanced urothelial cancer. The evidence supporting the claims of the authors is convincing, using a range of corroborative statistical techniques.

    1. eLife assessment

      Using continuum theory of elastic solids the authors present evidence that periodic muscle contraction leads to elongation of C. elegans embryos by storing elastic energy that is subsequently released by extending the embryo's long axis. This important finding could apply to other developmental processes and be exploited in soft robotics. The presented evidence is convincing on the phenomenological level adopted in the work. How bending energy is converted into elongation on a more microscopic level remains to be worked out.

      This valuable manuscript reports on the relationship between GTP hydrolysis parameters and kinase activity of LRRK2, which is associated with Parkinson's disease. The authors provide a detailed accounting of the catalytic efficiency of the ROC GTPase domain of pathogenic variants of LRRK2, in comparison with the wild-type enzyme. The authors propose that phosphorylation of T1343 inhibits kinase activity and influences monomer-dimer transitions, but the experimental evidence is currently incomplete.

    1. eLife assessment

      This useful manuscript explores conditions for epigenetic inheritance by studying the stability of simple network models to permanent and transient perturbations. A novel aspect of the study is that it unifies non-genetic inheritance phenomena across cell divisions of unicellular organisms and in the germline of multicellular organisms. However, the models studied are more a collection of vignettes of numerical studies than a systematic study, therefore the evidence presented remains incomplete. As a first step towards building a more systematic theoretical framework, this work will be of interest to colleagues in the field of epigenetic inheritance.

    1. eLife assessment

      This fundamental study reports compelling findings that intermediate states exist in epithelial-mesenchymal transition (EMT) during natural development and differentiation of mammalian neural crest cells, similar to recent reports in cancer. The authors determined that there were at least two paths to delamination and migration - one that occurs during S-phase of cell cycle and another during G2/M phase, and that the process of delamination is not restricted to cell fate. Finally, the authors showed that expression of Dlc1 may be used to identify cells in an intermediate state of EMT as well as their spatial location in the mouse embryo. The work will be of interest to developmental biologists, neurobiologists and cancer researchers.

    1. eLife assessment

      This valuable study by Bartas and colleagues examined how patterns of monosynaptic input to specific cell types in the ventral tegmental area are altered by drugs of abuse. The authors applied a dimensionality reduction approach (principal component analysis) and showed that various drugs of abuse, and somewhat surprisingly the anesthesia alone (ketamine/xylasin), caused changes in the distribution of inputs labeled by the transsynaptic rabies virus. While there are some issues to be addressed, the evidence supporting the conclusions is overall solid, and provides information that is of value to the field, as well as a cautionary note on the interpretation of rabies virus-based tracing experiments.

    1. eLife assessment

      This study makes a valuable contribution to spatial transcriptomics by rigorously benchmarking cell-type deconvolution methods, assessing their performance across diverse datasets with a focus on biologically relevant, previously unconsidered aspects.

By implementing a full Nextflow pipeline, Docker containers, and a rigorous assessment of the simulator, this work offers robust insights that elevate the standards for future evaluations and provides a resource for those seeking to improve or develop new deconvolution methods. The thorough comparison and analysis of methods, coupled with a strong emphasis on reproducibility, provide solid support for the findings.

    1. eLife assessment

      This study represents a valuable step toward understanding how brain connectivity changes during reward-based motor learning. However, the evidence presented is incomplete.

The data supporting the authors' conclusions on TBI analysis, RNA-seq on FACS sorted astrocytes, genetic analyses on Pvr-JNK/MMP1 are solid. However, cellular aspects of the response to TBI, statistical analysis, and molecular links between Pvr-AP1 are incomplete, which could be further strengthened in the future by more rigorous analyses.

    1. eLife assessment

      Dasgupta and colleagues make a valuable contribution to the understanding how the guidance factor Sema7a promotes connections between mechanosensory hair cells and afferent neurons of the zebrafish lateral line system.

Additional work is needed to distinguish the effects of different isoforms of Sema7a to determine whether there are specific roles of secreted and membrane bound forms.

    1. eLife assessment

      This important study discovered DBT as a novel gene implicated in the resistance to MG132-mediated cytotoxicity and potentially also in the pathogenesis of ALS and FTD, two fatal neurodegenerative diseases.

This work will be of interest to cell biologists and biochemists, especially in the FTD/ALS field.

    1. eLife assessment

      This article presents important results describing how the gathering, integration, and broadcasting of information in the brain changes when consciousness is lost either through anesthesia or injury. They provide convincing evidence to support their conclusions, although the paper relies on a single analysis tool (partial information decomposition) and could benefit from a clearer explication of its conceptual basis, methodology, and results. The work will be of interest to both neuroscientists and clinicians interested in fundamental and clinical aspects of consciousness.

    1. eLife assessment

      This valuable study investigates the role of mechanosensory feedback during swallowing in adult Drosophila. The authors provide convincing evidence that three mechanotransduction channel genes are required for ingestion rhythms and localize the role of these genes to a specific subpopulation of pharyngeal mechanosensory neurons. However, there is incomplete evidence to support the conclusions that these sensory neurons are necessary for swallowing, respond to stretch during swallowing, and connect to the motor neurons that control swallowing. This work may be of interest to neuroscientists interested in motor control of feeding behavior.

    1. eLife assessment

      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.

      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, current evidence is still incomplete as several of the conclusions from the paper stand in contradiction to other published findings and the authors naturally suggests experiments that will be needed in the future to validate the hypothesized pathways and refute existing published data. Such future validation includes animal models with tissue specific knockout of the key enzymes probed in the study; inhibiting the targets of this study with more than 1 small molecule that is structurally different, and at different doses and timings; using retinal explants from matured animals; performing labeled metabolite tracing experiments; and direct assessment of mitochondrial function (via OCR) under various manipulations.

    1. eLife assessment

      The valuable findings in this study show that subpopulations of peripheral sensory neurons display different capacities for regeneration after a similar injury. Nociceptor neurons have greater regeneration over mechanoreceptor, proprioceptors and motor neurons. This differential responsiveness of neuronal subtypes was traced to activation of different transcriptional programs, which were carefully analyzed and quantitated, resulting in solid evidence for the conclusions.

    1. eLife assessment

      The authors identify a population of neurons with a specific complement of markers that originate in a distinct location from where cerebellar nuclear precursor cells have been thought to originate, that show distinct developmental properties. The discovery of a new germinal zone giving rise to a new population of CN neurons is an important finding, and it enriches our understanding of cerebellar development. The claims are supported by solid evidence and the authors use a wide range of technical approaches, including transgenic mice, that allow them to disentangle the influence of distinct developmental organizers.

The cryo-EM structural characterization of the system is solid, but some open questions remain about the interpretation of activity/binding assays and the newly incorporated HDX-MS results. The work will be of interest to biochemists and structural biologists working on ribonucleotide reductases and other allosterically regulated enzymes.

    1. eLife assessment

      This useful study tests the hypothesis that Mycobacterium tuberculosis infection increases glycolysis in monocytes, which alters their capacity to migrate to lymph nodes as monocyte-derived dendritic cells. The authors conclude that infected monocytes are metabolically pre-conditioned to differentiate, with reduced expression of Hif1a and a glycolytically exhaustive phenotype, resulting in low migratory and immunologic potential. However, the evidence is incomplete as the use of live and dead mycobacteria still limits the ability to draw firm conclusions. The study will be of interest to microbiologists and infectious disease scientists.

    1. eLife assessment

      The microRNA lin-4, originally discovered in C. elegans, has a key role in controlling developmental timing across species, but how its expression is developmentally regulated is poorly understood.

      This study explores the physical principles underlying fluid flow and luminal transport within the endoplasmic reticulum; its important contribution is to highlight the strong physical constraints imposed by viscous dissipation in nanoscopic tubular networks. In particular, the work presents convincing evidence that commonly discussed mechanisms such as tubular contraction are unlikely to be at the origin of the observed transport velocities. As this study is solely theoretical and concerned with order of magnitude estimates, its main conclusions await experimental validation. The work will be of relevance to cell biologists and physicists interested in organelle dynamics.

The method represents an important advance in the study of natural genetic variation. The findings, especially given the follow-up validation of the phenotypic impact of a mapped locus of major effect, provide convincing support for the rigor and utility of the method.

      In this valuable study, the authors use Staphylococcus aureus to understand how organic acids inhibit bacterial growth. They provide convincing evidence that acetic acid specifically inhibits the activity of the Ddl enzyme and that S. aureus maintains a high intracellular D-ala concentration to circumvent acetate-mediated growth inhibition. This work will be of interest to researchers studying bacteria and antimicrobials.

      This study examines an important aspect of the development of the auditory system, the role of guanine nucleotide-binding protein subunits, GNAIs, in stereociliary bundle formation and orientation, by examining bundle phenotypes in multiple compound GNAI mutants. The experiments are highly rigorous and thorough and include detailed quantifications of bundle morphologies and changes. The depth and care of the study are impressive, with convincing results regarding the roles of GNAIs in stereociliary bundle development. Further, the reviewers believe this to be the definitive study of the role of GNAIs in bundle orientation and development.

      In this important paper, the authors propose a computational model for understanding how the dynamics of neural representations may lead to specific patterns of errors as observed in working memory tasks. The paper provides solid evidence showing how a two-area model of sensory-memory interactions can account for the error patterns reported in orientation estimation tasks with delays. By integrating ideas from efficient coding and attractor networks, the resulting theoretical framework is appealing, and nicely captures some basic patterns of behavior data and the distributed nature of memory representation as reported in prior neurophysiological studies. The paper can be strengthened if (i) further analyses are conducted to deepen our understanding of the circuit mechanisms underlying the behavior effects; (ii) the necessity of the two-area network model is better justified; (iii) the nuanced aspects of the behavior that are not captured by the current model are discussed in more detail.

      This important study reports human single-neuron recordings in subcortical structures while participants performed a tactile detection task around the perceptual threshold. The study and the analyses are well conducted and provide solid evidence that the thalamus and the subthalamic nucleus contain neurons whose activity correlates with the task, with stimulus presentation, and even with whether the stimulation is consciously detected or not. The study will be relevant for researchers interested in the role of subcortical structures in tactile perception and the neural correlates of consciousness.

      This valuable study provides incomplete evidence that white matter diffusion imaging of the right superior longitudinal fasciculus might help to develop a predictive biomarker of chronic back pain chronicity. The results are based on a discovery-replication approach with different cohorts, but the sample size is limited, and the clinical relevance is overstated. The findings will interest researchers interested in the brain mechanisms of chronic pain and in developing brain-based biomarkers of chronic pain.

      This study is valuable in that it aims to demonstrate that genomic insertion of a G4-containing sequence can be sufficient to induce chromosome loops and alter gene expression. However, the evidence remains incomplete because it has not been shown yet that the inserted sequence indeed forms G4 structures in cells and that the observed effects are caused by these structures and not by other elements present in the inserted sequence. Testing of different G4 sequences and other loci would be required to generalize the findings.

      This important study presents a significant methodological advance by leveraging previously discarded, unmapped DNA sequence reads to estimate pest infestation loads across plant accessions, and map variation in these apparent pest loads to defense genes. While the bioinformatics approach is convincing, the study appears incomplete because actual pest infestation was not systematically quantified, and thus loads inferred from sequencing reads are not validated. The results could have broad implications for phenotype-genotype prediction, especially regarding the use of unmapped reads for GWAS.

      It is well-established that cellulose synthesis in higher plants requires three different but related catalytic subunits known as CESA proteins. Here the authors provide convincing cryo-electron microscopy structural information on soybean CESA1, CESA3, and CESA6 and find substantial differences between the structure of these CESA homotrimers and the previously-resolved secondary cell wall CESAs. They present an important model in which the multi-subunit cellulose synthase complexes are made of multiple homotrimers but further evidence is needed to strengthen the conclusions.

      The manuscript addresses an important subject regarding the effects of the consumption of artificially sweetened beverages. The authors used zebrafish embryos treated with high concentrations of monosaccharides and observed hyperangiogenic characteristics similar to those seen in proliferative diabetic retinopathy. Their findings suggest that caloric and noncaloric monosaccharides induce excessive angiogenesis via the foxo1a-Marcksl1a pathway, but the evidence is currently incomplete.

    1. eLife assessment

      This important study sheds light on several apparent discrepancies observed across animal studies examining neuroimaging biomarkers of functional recovery following focal ischemia. Using 2-photon imaging of calcium activity in awake mice, the authors show compelling evidence that deficits in neuronal activity and functional connectivity after photothrombosis occur within a very small distance from the infarct (<750 microns) whereas these measures were relatively unaltered more distally, even those typically implicated with functional remapping of the forelimb representation in anaesthetized animals. These findings reveal a complex spatiotemporal relationship between perilesional neuronal network function and behavioral recovery that is more nuanced than previously reported, and motivates the need for better criteria for what is considered remapping.

      This is a valuable study that describes the effects of T. pallidum on neural development by applying single-cell RNA sequencing to an iPSC-derived brain organoid model. The evidence supporting the claims of the authors is solid, although further evidence to understand the differences in infection rates would strengthen the conclusions of the study. In particular, the conclusions would be strengthened by validating infection efficiency as this can impact the interpretation of single-cell sequencing results, and how these metrics affect organoid size as well as comparison with additional infectious agents. Furthermore, additional validations of downstream effectors are not adequate and could be improved.

      This valuable work describes a highly complex automated algorithm for analyzing vascular imaging data from two-photon microscopy. This tool has the potential to fill gaps in knowledge of hemodynamic activity across a regional network.

We believe these concerns could be addressed.

      The study employs single-molecule tracking to provide-- albeit currently inadequate - evidence that a phosphosite (S938) previously identified in the immune receptor kinase FLS2 is required for its recruitment into nanodomains and for endocytosis after flg22 treatment. As this site is known to be essential for FLS2 signaling, the findings are potentially important and suggest a key role of phosphorylation-dependent nanodomain localization for FLS2 signaling.

      This important study presents a framework for combining metagenomic and metabolomic data with genome-scale metabolic models to identify trophic interactions in a root microbiome. Its new approach to integrating these sources of data and model-specific trophic exchanges is compelling, but the benchmarking of the model generation process is incomplete and would benefit from a sensitivity and specificity analysis. With a stronger characterization of their method, this paper could be broadly applicable to other microbiomes and used to understand the composition and functioning of a given community, generate hypotheses, and design interventions.

      This study presents a useful deep learning-based inter-protein contact prediction method named PLMGraph-Inter which combines protein language models and geometric graphs. The evidence supporting the claims of the authors is solid. The authors show that their approach may be used in cases where AlphaFold-Multimer performs poorly. This work will be of interest to researchers working on protein complex structure prediction, particularly when accurate experimental structures are available for one or both of the monomers in isolation.

    1. eLife assessment

      This important paper provides solid evidence for an alternative conceptualization of the functional role of the place and grid cell network in the medial temporal lobe for memory as opposed to spatial processing or navigation. The theory accounts for many experimental results and generates predictions for future studies. The theory's simplicity and potential explanatory power will be of interest to researchers in this field. The impact of the work at present is limited by insufficient evidence for the advantage of this model over prior models, especially as the theory does not appear to fit with some well-established existing data.

    1. eLife assessment

      This is a useful study describing an implementation of awake mouse fMRI with implanted head coils at high fields. The evidence presented is solid but could with some work become stronger. In particular, the authors need to better contextualize their work with the existing literature on awake fMRI, include further details regarding their experimental methods, and further discuss some of their unexpected (but potentially novel and interesting) brain activations.

      In this study, the authors develop a strategy for fluorophore-tagging endogenous proteins in human induced pluripotent stem cells (iPSCs) using a split mNeonGreen approach, and they conclude that the system will be appropriate for performing live imaging studies of highly dynamic cellular processes such as cytokinesis in iPSCs. Experimentally, the methods are solid, and the data presented support the authors' conclusions. Overall, these methodologies should be useful to a wide audience of cell biologists who want to study protein localization and dynamics at endogenous levels in iPSCs.

      This useful study introduces a simple mechanical model of C. elegans locomotion that captures aspects of the worm's behavioral repertoire beyond forward crawling. While the kinetic model (ElegansBot) provides a compromise and starting point to help understand the mechanical components of C. elegans behavior, the claim that this work improves on extant mechanical models is incomplete, including modeling a 3-dimensional turning behavior with a 2-dimensional model without sufficient justification. In addition, the results of the application of the model to previously unstudied behaviors are primarily qualitative and do not produce new predictions.

      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. The demonstration of the effect of systemic inflammation on bone loss is convincing. Building on prior work, this study sets the scene for additional genetic and pharmacologic experiments as well as future analyses of the bone phenotypes, which should speak to the mechanisms involved in doxorubicin-induced bone loss – which are not addressed in the current study – and which may substantiate the clinical relevance of targeting inflammation in order to limit the negative impact of chemotherapies on bone quality.

      This fundamental work advances our understanding of the role of Cbfβ in maintaining articular cartilage homeostasis and the underlying mechanisms.

      This important study combines in vivo and in vitro models to characterise the role of CYRI-B, an interactor of the small GTPase Rac1, in controlling pancreatic cancer progression towards a higher proliferative and metastatic stage. The evidence supporting the claims of the authors is convincing in characterizing a novel Rac1 binding protein, CYRI-B, as a regulator of metastatic potential in vivo, with distinct functions at different stages of tumour progression. CYRI-B reduces the typical hyperactivation of Rac1 in the early stages of tumour progression; subsequently, CYRI-B mediates internalization of lysophosphatidic acid receptor 1 (LPAR1) uptake through macropinocytosis, thus regulating chemotactic migration of cancer cells towards lysophosphatidic acid (LPA). Although the inclusion of human pancreatic cancer cell lines would have strengthened the study, the work will be of broad interest to cell biologists and the signalling research communities.

    1. eLife assessment

      This study presents an interesting set of findings that connects N-cadherin and glypican-4 to Slit signaling during the regulation of contact inhibition of locomotion of Schwann cells in culture. Solid evidence is provided showing that N-cadherin not only regulates cell recognition but also proper trafficking of Slit to the cell surface. An ex-vivo model demonstrates the importance of Slit signaling during cell migration but the molecular details of how N-cadherin traffics Slit to the surface and role of glypican are unclear. The data would have been strengthened with a similar interrogation of N-cadherin in this system. The work will be of interest to cell biologists studying the mechanisms behind peripheral nervous system regeneration.

      This work presents a potentially important behavioral finding: that perceptual learning may not only improve but also distort the appearance of visual stimuli. The strength of the presented evidence in support of the main claim is however incomplete, and requires further analyses to confirm that perceptual learning does increase overestimation bias, and clarify why a very large baseline overestimation bias is present in the data.

      This important study provides a new, apparently high-performance algorithm for B cell clonal family inference. The new algorithm is highly innovative and based on a rigorous probabilistic analysis of the relevant biological processes and their imprint on the resulting sequences, however, the strength of evidence regarding the algorithm's performance is incomplete, due to (1) a lack of clarity regarding how different data sets were used for different steps during algorithm development and validation, resulting in concerns of circularity, (2) a lack of detail regarding the settings for competitor programs during benchmarking, and (3) method development, data simulation for method validation, and empirical analyses all based on the B cell repertoire of a single subject. With clarity around these issues and application to a more diverse set of real samples, this paper could be fundamental to immunologists and important to any researcher or clinician utilizing B cell receptor repertoires in their field (e.g., cancer immunology).

      The authors present a critique of current usage of principal component analysis in geometric morphometrics, making a convincing case with benchmark data that standard techniques perform poorly. The work is an important contribution to the field and will hopefully lead to a reassessment of the methodology most scientists in morphometrics currently use. The authors also present a new Python package that uses machine learning to provide better-supported results than principal component analysis. While the package is in the title of the manuscript, it is not its main focus.

      This study explores the interplay between fungal colonization and controlled programmed cell death in Arabidopsis thaliana root cells. The authors reveal how this process is affected by corpse clearance in the root cap, highlighting some of the key elements in this process including a root cap-specific transcription factor. With this, the authors have discovered an important relationship between transcriptional regulation of developmentally controlled cell death and the beneficial colonization of plants by fungi. The work thus establishes a solid basis for further studies of plant-microbiome associations along the root axis.

      This important work addressed the identifcation of antimalarial drug resistance mutations that do not readily transmit to new human hosts, focusing on azithromycin resistance. The technically challenging analyses of azithromycin-resistant parasites as they traverse the mosquito host and human liver are conducted using state-of-the-art tools, including humanized mice. While the claim regarding the lack of transmission by atovaquone-resistant P. berghei is convincing, the evidence for the lack of transmission by atovaquone-resistant P. falciparum is insufficient. This work will appeal to biologists and biomedical scientists in parasitology and drug discovery, offering insights into combating antimalarial drug resistance and understanding the fitness costs associated with drug-resistant parasites.

Using the Drosophila pupal notum as a model, the paper provides an elegant, thorough, descriptive characterisation of syncytia-driven wound closure using state-of-the-art confocal live imaging of the pupal notum. The authors meticulously characterize the cell-cell fusion events during wound healing, but without any mechanisms to inhibit cell fusion, it is incomplete, since it remains unclear whether cell fusion is required or not for speeding wound healing and/ or increasing the level of actin resources at the leading edge.

      This important study describes the new observation that nuclear volume responds to confinement in a manner that requires transit through mitosis. The authors present solid evidence demonstrating that nuclear volume decreases upon nuclear envelope reformation under confinement in a manner that reestablishes a homeostatic state of nuclear envelope tension. Additional experimental support could provide a more complete case for the proposed underlying mechanisms governing this response. The work will be of broad interest to cell biologists and those interested in cell and organismal scaling.

      Tatekoshi et al. endeavored to utilize human-induced pluripotent stem cell-derived cardiomyocytes to create an in vitro model of Heart Failure with preserved Ejection Fraction (HFpEF) to investigate the impacts of inflammation, sera from HIV patients, and the application of cardioprotective and antiviral medications on cardiomyocyte relaxation as a proxy for diastolic function. Their investigations revealed that inflammatory cytokines lead to an increased decay in calcium transients, a process that could be alleviated through the use of SGLT2 inhibitors and mitochondrial antioxidants. These results indicate that inflammation might contribute to diastolic dysfunction and suggest that SGLT2 inhibitors and mitochondrial antioxidants could offer cardioprotective benefits by reducing inflammation in cardiomyocytes. These valuable, yet incomplete results, can be complemented by employing biomechanical and molecular analyses, alongside validation of the therapeutic duration and dosages.
