  This fundamental study analyzes the roles of post-translational modifications of tubulin by generating a large panel of tubulin mutants and describing their effects on morphogenesis and function of sensory neurons in C. elegans. The work, which is of interest to all cell biologists, in particular researchers with an interest in the microtubule cytoskeleton and neurobiology, presents conclusions that are supported by solid evidence. Demonstrating that all introduced mutations have the intended consequences and exploring their direct effect on microtubules would further increase the impact of the work.

  How the triplicate interaction between chemokines with both GAGs and G protein-coupled receptors (GPCR) works and how gradients are created and potentially maintained in vivo are poorly understood. The authors provide solid evidence to show phase separation can drive chemotactic gradient formation. The paper is a useful advance in the field of chemokine biology.

  This valuable study reports that actin-related proteins may be involved in transcriptional regulation during spermatogenesis. The supporting data remain incomplete, and more extensive disentanglement from the canonical role of these actin-related proteins and the experimental validation of in silico predictions are required. This work will be of interest to reproductive biologists and other researchers working on non-canonical roles of actin and actin-related proteins.

  eLife assessment

  This study reports that the timing of 'brain-to-gut' signaling influences the lifespan of the C. elegans model. The main finding, that modulating the same neurotransmitter, Acetylcholine, at different ages elicits lifespan shortening - or extending - effects utilizing different receptors, is important and of broad interest to the longevity field as recognized by all the reviewers. The data is largely consistent with the authors' model, but the strength of the evidence is incomplete. The study requires several rigorous experiments detailed by the reviewers to substantiate the main conclusions.

  This important manuscript used state-of-the-art techniques and employed relevant animal models to provide both convincing and solid evidence supporting the regulatory role of microRNA cluster 221/222 in rheumatoid arthritis synovial fibroblast. The findings of this work offer significant advances to current knowledge which will be interesting to a wide range audience in the rheumatology and bone research fields. However, whereas models, techniques, and analyses are solid, certain concepts related to the role of immune and bone cells are limited.
