This study investigates the role of Hox genes in determining the position of the forelimb bud using experimental loss- and gain-of-function approaches in chicken embryos, concluding that Hox4 and Hox5 provide permissive signals for forelimb formation throughout the neck region, while the final forelimb position is determined by the instructive signals of Hox6/7 in the lateral plate mesoderm. These results could potentially be fundamental to our understanding of Hox patterning. However, the evidence supporting these conclusions is incomplete; while the gain-of-function experiments are well supported, the loss-of-function experiments using dominant-negative constructs lack sufficient controls, and could be the result of an experimental artifact.

This important study provides insights into the role of maternal behavior in the learning and ontogeny of vocalization. It finds evidence that the maternal behavior of sac-winged bats (Saccopteryx bilineata) can influence the learned territorial songs of their pups. The behavioral analyses are convincing, using longitudinal acoustic recordings and behavioral monitoring of individual mother-pup pairs across development and multiple wild bat colonies. The work will be relevant to a broad audience interested in the evolution and development of social behavior as well as sensory-motor learning.

These are valuable findings for those interested in how neural signals reflect auditory speech streams, and in understanding the roles of prediction, attention, and eye movements in this tracking. However, the evidence as it stands is incomplete. Further analyses are needed to clarify how the observed results relate to the relevant theoretical claims.

eLife Assessment

This is an important study demonstrating that cholecystokinin is a key modulator of auditory thalamocortical plasticity during development and in young adult but not aged mice, though cortical application of this neuropeptide in older animals appears to go some way to restoring this age-dependent loss in plasticity. A strength of this work is the use of multiple experimental approaches, which together provide convincing support for the proposed involvement of cholecystokinin. This work is likely to be influential in opening up a new avenue of investigation into the roles of neuropeptides in sensory plasticity.

This useful study reveals that as C. elegans, a poikilothermic ("cold-blooded") animal, adapt to cold (4ºC), they display a drastic reduction in translation (assessed by polysome profiling and SUNSET). The remaining translation (by ribo-seq) correlates with mRNA levels (by RNA-seq), and the changes in gene expression at least partially require IRE-1, an established endoplasmic reticulum stress sensor. The reviewers consider the data assessing global translation and RNA expression upon cold exposure and the data demonstrating the requirement of ire-1 to be solid, but the conclusion that "transcription" is the major regulatory step and "lipid changes" can be a signal for IRE-1 activation in cold adapted worms needs substantially more evidence. Overall, this study demonstrated a good correlation between translation and RNA levels and yielded an inventory of gene changes as C. elegans adapt to cold, and will be of general interest to researchers interested in stress response and cold adaptation.

In this important study, the authors reconstruct the evolutionary history of a large and widespread group of freshwater fishes (Nemacheilidae) across Eurasia since the early Eocene, based on molecular phylogenetic analysis with very comprehensive samplings including 471 specimens belonging to 250 living species. The authors convincingly infer that range expansions of the family were facilitated by tectonic connections, favorable climatic conditions, and orogenic processes, adding to our understanding of the effects of climatic change on biodiversity during the Cenozoic. This work is of interest to evolutionary biologists, ichthyologists, paleontologists, and general readers.

eLife Assessment

This important study highlights the key role of the gut-liver axis mediated by LPS in causing hepatic steatosis. The authors provide solid evidence, in vivo, in vitro, and in silico, for the role of acyloxyacyl hydrolase in mediating this effect using KO mice subjected to MASD-inducing diets. The findings are significant for the liver research community and others interested in the gut-liver axis.

eLife Assessment

This important study provides convincing evidence that the Kinesin protein family member KIF7 regulates the development of the cerebral cortex and its connectivity and the specificity of Sonic Hedgehog signaling by controlling the details of Gli repressor vs activator functions. This study provides new insights into general aspects of cortical development.

eLife Assessment

In this useful study, the authors utilize published scRNA-seq data to highlight the potential importance of mast cells (MCs) in TB granulomas, presenting a solid comparative assessment of chymase- and tryptase-expressing MCs in the lungs of Mycobacterium tuberculosis-infected individuals and non-human primates. While the authors appropriately discussed the inconsistencies across models, adoptive transfer experiments in MC-deficient mice would substantially strengthen the causal link between MCs and TB outcomes, providing more direct functional validation of the proposed role of MCs in TB pathogenesis.

eLife Assessment

This valuable study provides in-vivo evidence that CCR4 regulates the early inflammatory response during atherosclerotic plaque formation. The authors propose that altered T-cell response plays a role in this process, shedding light on mechanisms that may be of interest to medical biologists, biochemists, cell biologists, and immunologists. The work is currently considered incomplete pending textual changes and the inclusion of proper controls.

eLife Assessment

This study describes a useful technique to improve imaging depth using confocal microscopy for imaging large, cleared samples. The work is supported by solid findings and will be of broad interest to many microscopical researchers in different fields who want a cost effective way to image deep into samples.

eLife Assessment

This timely and important study used functional near-infrared spectroscopy hyperscanning to examine the neural correlates of how group identification influences collective behavior. The work provides solid evidence to indicate that the synchronization of brain activity between different people underlies collective performance and that changes in brain activity patterns within individuals may, in turn, underlie this between-person synchrony, although the order in which different task stages were completed could not be counter-balanced. This study will be of interest to researchers investigating the neuroscience of social behaviour.

eLife Assessment

This study presents a valuable finding on the mechanism of self-prioritization by revealing the influence of self-associations on early attentional selection. The evidence supporting the claims of the authors is solid, although inclusion of a discussion about the generalization and limitation would have strengthened the study. The work will be of interest to researchers in psychology, cognitive science, and neuroscience.

This valuable study investigates both online responses to, and offline replay of, visual motion sequences. Sophisticated MEG analyses provide convincing evidence for both feature-specific and non-specific sequence representations. These intriguing findings will be of interest to perception and learning researchers alike.

eLife Assessment

This study focuses on a previously reported positive correlation between translational efficiency and protein noise. Using mathematical modeling and analysis of experimental data the authors reach the valuable conclusion that this phenomenon arises due to ribosomal demand. While some aspects of the work appear to be incomplete, the results have the potential to be of value and interest to the field of gene expression.

eLife Assessment

This study presents a valuable finding on how the interplay between transcription factors SOX2 and OCT4 establishes the pluripotency network in early mouse embryos. The evidence supporting the claims of the authors is solid, although inclusion of additional omics data would further strengthen the study. The work will be of interest to biologists working on embryonic development and gene regulation.

eLife Assessment

This valuable study provides a detailed picture of the synapse distributions for a set of visual projection neurons and their downstream partners, in combination with multi-compartmental modelling fitted to electrophysiological data. The model reveals interesting consequences of synapse topography for neuronal computation. The analysis, however, seems incomplete as the authors only analyze passive models of these spiking neurons, and do not attempt to connect their analysis to the bigger picture at the behavioral level.

eLife Assessment

This important study shows that Toxoplasma gondii uses paracrine mechanisms, in addition to cell-intrinsic methods, to evade the host immune system, with MYR1 playing a key role in transporting effector molecules into host cells. The authors present convincing evidence that in vivo, MYR1-deficient parasites can be rescued by wild-type parasites, revealing a limitation in pooled CRISPR screens, where such paracrine effects may obscure the identification of key parasite pathways involved in immune evasion

eLife Assessment

This study reports an important finding on the mechanism underlying the enhancement of anti-viral immune responses by febrile temperatures, especially the role of the conserved heat-shock factor, HSF-1. The data provide compelling support for the authors' model wherein increased temperature in the shrimp Litopenaeus vannamei activates HSF1, which in turn enhances anti-viral response via up-regulation of the nSWD protein and antibacterial peptides. The work, which will be of interest to virologists, immunologists, and cell biologists, would benefit from more discussion of the function and roles of HSF-1 at 25°C vs. 32°C.
