    Mucosal-associated invariant T (MAIT) cells are key in immunity and diseases, but how their effector polarization is controlled is still unclear. Here, the authors show that an IL-1β/IL-23/mTORC2 axis is essential for the induction of IL-17-producing MAIT17, while an IL-2/IL-15/mTORC1 axis is important for the homeostasis of IFN-γ-producing MAIT1.

    High mitogenic stimuli have been suggested to promote endothelial cell proliferation and sprouting during angiogenesis. Here Pontes-Quero et al., by interfering with levels of VEGF and Notch signalling in single endothelial cells in vivo, find that high mitogenic stimuli instead arrest angiogenesis due to a bell-shaped dose-response to VEGF and MAPK activity that is counteracted by Notch and p21.

    At high cell density or when plated on soft matrix, YAP/TAZ are redistributed from the nucleus to the cytosol, becoming transcriptionally inactive. Here the authors show that at high cell density, autophagosome formation is impaired due to reduced YAP/TAZ-dependent transcription of actomyosin genes

    VEGF-C is a key regulator of lymphatic development. Here, Zhang et al. show that while complete loss of its receptor VEGFR3 results in vessel hypoplasia, mosaic loss of VEGFR3 leads to hyperplasia through induction of cell proliferation in neighboringnon-targeted cells, uncovering cell- and non-cell-autonomous roles for VEGFR3 during lymphatic vessel growth.

    Mutations in the gene encoding iRHOM2 are associated with hyperproliferative epidermal disorders. Here, the authors show that iRHOM2 is a target gene of p63, that together they regulate inflammation, cell survival and response to oxidative stress, and inhibition of p63-iRHOM2 signalling with an antioxidant reduces epidermal inflammation.

    During early postnatal development in mammals, cardiomyocytes exit the cell cycle, losing their regenerative capacity. Here the authors show that, following myocardial infarction, loss of microRNA-128 promotes cardiomyocyte proliferation and cardiac regeneration in adult mice partly via enhancing the expression of the chromatin modifier SUZ12.
