  In this manuscript, the authors analyse the nanoscale localisation of α5β1 and αVβ3 integrins in integrin adhesion complexes (IAC) by dual-colour STORM and assess the spatial organisation at the nano and mesoscale of their main adaptors (paxillin, talin and vinculin). This is an important work that provides detailed analyses that reveal how elements of these complex structures are really organised at the nanoscale, an essential perspective for a better understanding of how IACs function and regulate mechanotransduction processes. The evidence presented is solid, with super-resolution imaging experiments conducted using a single, validated methodology and subsequent computational modelling that enabled a quantitative assessment of the resulting data.

  This valuable study determines the functional requirements for localization and activity of S. cerevisiae septin-associated kinases using in vivo imaging, in vitro and in vivo protein-protein interaction assays, and an instructive in vivo "tethering" approach. In addition to confirming previous results, the study offers evidence that the septin-associated kinases may directly interact with the contractile ring machinery. Although the experiments appear to have been conducted correctly, the quantitative analysis of some experiments is incomplete and should be improved to strengthen the conclusions.

  Goswami and colleagues used rod-specific Gls1 (the gene encoding glutaminase 1) knockout mice to investigate the role of GLS1 in photoreceptor health when GLS1 was deleted from developing or adult photoreceptor cells. This study is fundamental as it shows the critical role of glutamine catabolism in photoreceptor cell health using in vivo model systems. The evidence supporting the authors' claims is compelling. The studies add new insight into how specific metabolites support vision.

  This important work presents a self-supervised method for the segmentation of 3D cells in fluorescent microscopy images, conveniently packaged as a Napari plugin and tested on an annotated dataset. The segmentation method is solid and compares favorably to other learning-based methods and Otsu thresholding on four datasets, offering the possibility of eliminating time-consuming data labeling to speed up quantitative analysis. This work will be of interest to a wide variety of laboratories analysing fluorescently labeled images.

  The study presents valuable findings on the role of Aff3ir, a gene implicated in flow-induced atherosclerosis and regulating the inflammation-associated transcription factor, IRF5. The in vivo data are solid in providing evidence on the role of Aff3ir in shear stress and formation of atheromatous plaques. The work will be of interest to clinical researchers and biologists focusing on inflammation and atherosclerosis in cardiovascular disease with a broad eLife readership.
