This important study by Bonnet et al addresses the question of how AMPA receptor numbers at the synapse are regulated during basal conditions and during chemically induced Long Term Potentiation. Specifically, the study aims to determine the molecular mechanisms that contribute to the intracellular trafficking of AMPA receptors and determine their insertion into the synaptic plasma membrane. Using compelling methodology, the authors dissect the distinct roles of two proteins that bind to the C-terminal domain of the AMPA receptor subunit GluA1: 4.1N and SAP97. The findings will be of interest to anyone trying to understand molecular events contributing to synaptic plasticity in health and disease, and more broadly, the method could be adapted for tracking intracellular movements of a wide range of proteins.

The overarching question of the manuscript is important and the findings inform the patterns and mechanisms of phage-mediated bacterial competition, with implications for microbial evolution and antimicrobial resistance. The evidence in the manuscript is, however, still incomplete and some of the conclusions made are not supported by the data. This manuscript would additionally be strengthened by a clearer narrative, to enable readers to more easily extract the key message this paper wants to convey.

This is a well-done study to understand how Rab27 and its effectors regulate insulin secretion. The present work examines the relative hierarchy of exophilin-8 and melanophilin using single vs double knockouts and rescue experiments to show that melanophilin functions downstream of and potentially redundantly from Exo8. Imaging and protein co-localization studies were done in a rigorous way. The data are solid, and some additional data will make the work fully compelling. Overall this is an important study that sheds new light on the regulation of insulin granule exocytosis.

This important study reports that Foxc2+ cells in the testis represent the quiescent spermatogonial stem cells (SSCs). The data supporting this claim are solid. The finding is of great significance to reproductive and stem-cell biology as male fertility depends on the fine balance between self-renewal and differentiation activities of the male germline stem cells, i.e., SSCs.

This work presents important findings regarding the use of soil environmental DNA for non-invasive monitoring of the endangered kākāpō parrot population in New Zealand. The approach based on sequence analysis is convincing but comparisons to established methods are lacking. The tools presented in this study are innovative and will be relevant to those working with environmental DNA and the conservation of biodiversity.

eLife assessment

This valuable data study presents convincing data that expression of the C. elegans transcription factor NHR-67 is sufficient to drive an invasive fate, and that the alternative proliferative fate is associated with NHR-67 transcriptional down-regulation. While the observation that NHR-67 forms punctae associated with transcriptional repressors in non-invasive cells is intriguing, the work does not yet established a clear link between the formation and dissolution of NHR-67 condensates with the activation of downstream genes that NHR-67 is actively repressing. The work will be of interest to developmental biologists studying transcriptional control of cell fate specification in animals, especially once issues around the functional significance of the NHR-67 contiaining punctae are resolved.

This manuscript presents valuable findings that bring together two important topics in cell biology: the function of membrane contact sites and cell migration. The authors describe a role of the ER tether protein VAP-A in focal adhesion dynamics and cell motility. Although the authors present solid evidence to support some of the main claims of the paper, some of the other claims would benefit from stronger experimental support. Nonetheless, this paper will be of interest to those cell biologists and biophysicists working on adhesion, migration, and membrane contact site biology.

This paper is of interest for skeletal biologists studying bone marrow stem/progenitor cells and bone remodeling. Using Adipoq-Cre-driven conditional deletion of Csf1 that encodes M-CSF and reanalyzing publicly available scRNAseq data, the authors recognize a subpopulation of bone marrow cells (i.e. AdipoQ-lineage progenitors) as an important source of M-CSF. The authors found that M-CSF production from these bone marrow cells influences the development of macrophages and osteoclasts as well as bone mass, including the bone loss associated with estrogen deficiency. This is a clearly written and nicely presented study that has potential to offer important new information regarding the source of M-CSF in the bone marrow.

This paper is of interest to immunologists conducting single-cell analyses of T-cell recognition. It provides a means of curating datasets to ensure T cell-antigen pairs are identified. The data generated through this method often suffers from a relatively high background, so the authors present a computational approach to enhance the signal-to-noise of this type of analysis. At this stage, it is unclear if the thresholds and filtering steps described by the authors can be generally applied to other datasets of different qualities than the one used here.

This study presents a valuable mathematical model for the adaptive dynamics of cancer evolution in response to immune recognition. The mathematical analysis is rigorous and convincing, and overall the framework presented could be used in the future as a solid base for analytically tracking tumor evasion strategies. However additional discussion is needed to clarify certain gaps between the theory and cancer evolution in real systems. The work will be of interest to evolutionary cancer biologists and potentially it may also have implications for the design of clinical interventions.

This study presents a valuable finding on the critical features and patterns of m1A modification and in neurons and OGD/R-treated neurons. Moreover, the authors identified m1A modifications on different RNAs and explored the possible effects of m1A modification on the functions of different RNAs via an integrated approach of omics and bioinformatics. The evidence supporting the claims of the authors is solid, although inclusion of more in-depth studies to analyze the transcription factors for the upstream regulation would have strengthened the study. The work will be of interest to neurobiologist and scientists in the field of RNAs.

Scott et al use Drosophila as a model to study the sialylation pathway and its role in nervous system function. Surprisingly, they find that the critical substrate for sialylation, CMP-Neu5Ac, is 'outsourced' to glia. This significant study presents a new twist in mechanisms underlying protein glycosylation and uncovers a new layer in the complex interplay of neurons and glia.
