      In flies defective for axonal transport of mitochondria, the authors report the upregulation of one subunit, the beta subunit, of the heterotrimeric eIF2 complex via mass spectroscopy proteome analysis. Neuronal overexpression of eIF2β phenocopied aspects of neuronal dysfunction observed when axonal transport of mitochondria was compromised. Conversely, lowering eIF2β expression suppressed aspects of neuronal dysfunction. While these are intriguing, potentially useful observations, several technical weaknesses limit the interpretation and mean the evidence supporting the current claims is incomplete.

      In this manuscript, the authors describe the creation of a transgenic mouse expressing a reporter for Integrated Stress Response (ISR) activation in a CRE-dependent manner. Reliable tools for detecting ISR activation in situ are lacking, so this manuscript describes a potentially valuable tool that builds on and overcomes some of the limitations of a similar viral vector described by the authors in a previous publication. Solid evidence suggests that distinct populations of cells (ChAT) in the nervous system are marked by some level of ISR activation, and that the mouse could be most helpful as a screen for cell types in which the ISR is particularly active, although it would be difficult to draw conclusions from the reporter alone. Additional validations of the reporter activity in situ will further strengthen the manuscript.

      This is an important study that reports the mechanism by which Ankle2 (LEM4 in humans) interacts with and recruits PP2A and the ER protein Vap33 to promote BAF dephosphorylation and mediate nuclear membrane reformation, using Drosophila as their model. Using Ankle2 mutants, they find that the ER protein Vap33 is key for the normal interphase localisation of Ankle2/LEM4 and also impacts on the function of Ankle2/LEM4 during mitosis. The conclusions on the subcellular localization of Ankle2 are drawn from overexpression of constructs. Overall, the authors use a variety of complementary techniques and provide convincing evidence to support the claims and advance our knowledge in the field of mitosis and nuclear envelope biology.

      This is a useful study that seeks to address the role of the TET family of DNA demethylation enzymes in pancreatic beta cell senescence in the context of type 2 diabetes (T2DM). Although the concepts are novel and of interest, the study presents incomplete evidence to fully support its main conclusions.

      This study presents important findings demonstrating that FZD5 and FZD8, two of the ten Frizzled proteins, undergo Wnt-mediated endocytosis. The E3 ubiquitin ligases RNF43/ZNRF3 regulate their degradation in a Wnt-dependent manner, a mechanism that was not previously recognized. The evidence supporting the claims of the authors is solid. This research will be of interest to biologists specializing in Wnt signaling, cancer, and regenerative medicine.

      The identification of NCS1 as a distal appendage protein that captures preciliary vesicles has important implications for understanding the early steps of ciliary assembly. Furthermore, the work has important implications for the broader understanding of NCS1, which prior to this work was focused on roles in neurotransmission, but now must be considered in a broader context. The investigators used a variety of state-of-the-art methodologies, and the conclusions are convincingly supported by the experimental data. This work will be of interest to cell biologists studying ciliary assembly, human geneticists exploring the pathology of cilia as well as neurobiologists studying NCS1.

      This fundamental work substantially advances our understanding of how the glycocalyx of cells provide a non-specific barrier for the interaction of viruses with cell-surface receptors. Using both in vitro experiments and in vivo manipulations they provide solid evidence for the properties of the glycocalyx to serve as an energy barrier as a main attribute of its mode of action. The work will be of broad interest to virologists and the cell biology community that studies host-pathogen interactions.
