The authors describe a valuable finding that the Streptococcus pyogenes secreted protease SpeB is expressed in response to protease activity that degrades the Vfr repressor. Proteases can be released from host neutrophils (possibly by NETosis), as well as a positive feedback mechanism by SpeB itself. The authors utilize a dual fluorescent reporter system to simultaneously read speB and capsule gene expression, providing solid evidence that demonstrates that proteases can regulate Vfr; however, the data indicating that this is physiologically relevant and that extracellular traps themselves are important is incomplete. This work will be of interest to microbiologists studying the regulation of virulence factors at the host-pathogen interface.

eLife Assessment

This fundamental study provides convincing evidence that distinct molecular mechanisms underlie AAV-associated retinal toxicity in retinal pigment epithelial cells and photoreceptors, advancing our understanding of gene therapy-related retinal injury. The authors employ a rigorous and comprehensive experimental approach, including multiple knockout mouse models, transcriptomic analyses, and genetic loss-of-function studies, which substantially strengthen the mechanistic conclusions. Some concerns remain regarding vector characterization, the absence of procedural injection controls, and the limited interpretation of adult versus neonatal studies; nevertheless, the study makes a substantial contribution to the field and provides a strong foundation for future translational investigations.

eLife Assessment

This paper reports the findings of a neuroimaging experiment that tested the hypothesis that the cortex, specifically early visual areas, reinstates certain content from past episodic events. This is a useful study that highlights the role of early sensory cortices in supporting rapid, one-shot learning of location information for long-term memory. The strength of the evidence is solid, with the methods, data, and analyses broadly supporting the claims.

eLife Assessment

This important study shows that NPAS4, a gene that is switched on by neural activity, enhances the spatial and temporal precision of hippocampal neurons during navigation. These findings, based on selective and sparse gene deletion, are supported by convincing evidence. However, the experiments were performed entirely in animals exposed to long-term environmental enrichment, which leaves open the question of whether the same effects would emerge under standard housing conditions. This study will be of interest to neuroscientists studying neuronal circuits and spatial coding.

eLife Assessment

This study provides a valuable advance in understanding how disordered proteins interact with cell membranes by identifying the sequence rules that enable aromatic residues to penetrate deeply into the membrane interior. The integration of complementary computational approaches, including molecular simulations, large-scale sequence analysis, and the development of an online prediction server, makes the work potentially impactful for the membrane protein and intrinsically disordered protein communities. The evidence supporting the main conclusions is generally convincing, although its transferability across diverse membrane compositions and its validity as a prediction tool for real protein-membrane systems remain to be further established.

eLife Assessment

This is an important study showing the interaction of the endoplasmic reticulum (ER)-resident tyrosine phosphatase PTP1B with the developing phagocytic cup in macrophages, and its role in inhibiting microbicidal superoxide production. The authors show convincing evidence that PTP1B interacts with Syk, a plasma membrane tyrosine kinase that plays an essential role in phagocytosis, and that ablation of PTP1B increases superoxide production and Syk phosphorylation without affecting phagocytosis. Further evidence suggests that PTP1B may inhibit a Syk/Shc1/NOX2 axis; however, robust demonstration of the proposed chain of events and of the actual role of ER-plasma membrane contact sites in the PTP1B-dependent downregulation of NOX2 activity will require additional experimental evidence. The integration of advanced imaging methods to study contact site formation with functional assays related to phagocytosis and signaling is inspiring.

eLife Assessment

This important study combines chromatin accessibility and genomic DNA sequence conservation data from low-coverage genome sequencing of related species (without assembly), for the in silico identification of cis-regulatory elements in large genomes. The approach and results are compelling and well supported by the experimental validations. The work will be of interest to researchers working in the field of gene regulation and evolution, particularly because the methodology proposed can be applied to a large variety of experimental organisms.

eLife Assessment

This useful study presents the first application of engineered NK-92 cell-derived extracellular vesicles displaying CD19 scFv for the treatment of systemic lupus erythematosus (SLE). The concept of using targeted extracellular vesicles as a "cell-free" alternative to CAR-T/CAR-NK therapies is good. However, the current results are incomplete and do not provide strong support for the experimental hypothesis, particularly with respect to EV purification, characterization, mechanistic validation, and adherence to current EV field standards. Several major concerns should be addressed to strengthen the translational relevance, reproducibility, and biological interpretation of the study.

eLife Assessment

This study provides fundamental insights into the mechanisms of visual object categorization in primates through a scalable behavioral framework for assessing category learning and generalization in macaque monkeys. The evidence is compelling, based on extensive behavioral characterization, rigorous control experiments, and comprehensive comparisons with humans and computational models, although extending the model analyses to the secondary monkey experiments would further strengthen the conclusions.

eLife Assessment

This important study presents a computational framework inspired by cycleGAN that enables denoising and realistic simulation of cryo-electron tomography data, addressing central challenges in tomogram cleaning, simulation, and downstream annotation. The approach coherently links several key problems in the field and demonstrates strong performance across benchmark datasets, with additional benefits for particle detection and missing-wedge completion, indicating broad relevance across electron tomography. The evidence is solid, with appropriate quantitative benchmarks and applications to diverse datasets supporting the main claims, although validation on additional, more recent tomograms would further strengthen the conclusions.

eLife Assessment

This important study clearly demonstrates that Sox17 is key for the formation and function of the Sertoli valve, a transition region between the rete testis and seminiferous tubules, which remains an understudied domain of testicular biology. The supporting data are generally convincing but remain incomplete. This work will be of interest to reproductive biologists and andrologists who work on male fertility and men's health.

eLife Assessment

In this valuable manuscript, the authors tackle a highly relevant question in biology: how cells integrate attractive and repulsive cues to achieve directed migration. They present solid data demonstrating that two wunen genes act as negative regulators of Hedgehog signalling, thereby enabling efficient primordial germ cell (PGC) migration in Drosophila embryos. Beyond its immediate scope, this work has broader implications, particularly for understanding key mechanisms underlying complex processes such as cancer metastasis, where the coordinated interpretation of guidance cues is critical.

eLife Assessment

The focus of this manuscript is a computational procedure to reveal signatures of selection on transcription factor binding sites through assessing changes in predicted binding affinity, setting out to avoid biases inherent in previous tests. The general approach could become a valuable resource for the community that can also be used for a broader range of questions. However, in its current implementation, the methods are inadequate to sufficiently support the primary claims.

eLife Assessment

This paper presents important findings on how the shapes of leaves might be biased towards simpler shapes due to biases in how variation is generated by developmental processes rather than selection. The authors present solid evidence that combines image analysis of a herbarium dataset and computational analysis of a model of leaf development. The paper should be of interest to diverse researchers, ranging from plant development to the evolution of complexity more broadly.

eLife Assessment

This useful study introduces a statistical model and accompanying software for jointly analysing how an organism's own genotype, and those of its neighbors, shape its traits (assessing both direct and indirect genetic effects), based on simulations and three datasets from plants. The implementation and its behavior on simulated data are solid, but the evidence that the approach is more powerful, more interpretable, or more novel than established alternatives is incomplete, because the authors do not benchmark against existing methods, nor validate the candidate genes they identify, nor test realistic scenarios in which neighbor effects are weaker than direct effects. The work will be of interest to quantitative geneticists and plant breeders studying competition among neighboring genotypes.

eLife Assessment

The framework of the study - with the integration of multiple levels of analysis, glymphatic MRI, transcriptomics, functional MRI, and public amyloid maps, in one framework - is clever. The assertion that regional amyloid vulnerability may depend not just on neural activity alone, but on whether clearance is appropriately matched to activity is an interesting and novel concept. However, the chosen approach to imaging glymphatic clearance relies on indirect inferences from a small subgroup. In its current form, the main conclusions of this study are therefore incompletely supported.

eLife Assessment

This valuable study advances our understanding of genes contributing to Drosophila resistance to octanoic acid, a primary toxin present in Morinda fruit, which is the natural host plant for Drosophila sechellia, a species that has become a model for understanding evolutionary specialization. The authors provide solid results from an original combination of experimental evolution and cell-based CRISPR screens. This work will be of interest to the Drosophila community and researchers interested in the genetic basis of polygenic traits.

eLife Assessment

This study of BDNF signaling in heterogeneous spinal cord cultures provides a fundamental conceptual advance by demonstrating that cell identity and maturation state, rather than receptor stoichiometry alone, ultimately determine how a trophic message is interpreted, in a framework the authors call "prepared competence." The evidence is compelling, with the discrete subpopulation behavior, the maturation-dependent acquisition of signaling competence, and the dissociation between receptor abundance and signaling output emerging clearly from the high-dimensional dataset. This study will be of interest to neurobiologists as well as cell biologists who study the molecular basis of cell signaling.

eLife Assessment

This study presents an important finding that loss or blockade of key integrins unexpectedly enhances central nervous system accumulation of T-cell acute lymphoblastic leukemia cells and may increase their sensitivity to chemotherapy. The evidence is convincing, supported by well-designed in vivo models, CRISPR-based perturbations, competitive assays, imaging, and complementary therapeutic experiments. However, the mechanistic basis linking integrin loss, altered spatial distribution, and increased proliferation remains incompletely defined, and the translational implications would be strengthened by additional survival studies and validation in more clinically relevant models.

eLife Assessment

This study provides important findings regarding the efficacy of a chronotherapeutic protocol (termed LiFE), combining timed light, food, and exercise exposure in improving several physiological and health metrics in a rodent model. The evidence advanced in wild-type mice is solid but inconclusive and underpowered when applied to two transgenic mouse models of Alzheimer's Disease. Additionally, the potential of such protocols in clinical human studies is an open question. Overall, the study suggests that LiFE intervention may have positive effects on metabolic and brain health.
