    Yolk-sac-derived macrophages progressively expand in the mouse kidney with age

    Shintaro Ide et al.
    A combination of genetic fate-mapping and parabiotic experiments reveals the chronological expansion of yolk-sac-derived renal tissue-resident macrophages with age by cellular proliferation and recruitment from circulating progenitors.

    The insulin/IGF signaling cascade modulates SUMOylation to regulate aging and proteostasis in Caenorhabditis elegans

    Lorna Moll et al.
    By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.

    Evaluating distributional regression strategies for modelling self-reported sexual age-mixing

    Timothy M Wolock et al.
    Integrating the sinh-arcsinh distribution into a distributional regression framework allows us to produce precise, local estimates of sexual age-mixing, facilitating more accurate modelling of sexually transmitted disease dynamics.

    Phosphatidylinositol 3-kinase and COPII generate LC3 lipidation vesicles from the ER-Golgi intermediate compartment

    Liang Ge et al.
    Building on previous work (Ge et al., 2013), it is shown that the ER-Golgi intermediate compartment is a platform for the production of COPII vesicles as precursor membranes for the lipidation of LC3, which is an essential step in autophagosome biogenesis.

    Ferroptotic stress promotes the accumulation of pro-inflammatory proximal tubular cells in maladaptive renal repair

    Shintaro Ide et al.
    Ferroptotic stress enhances the accumulation of damage-associated inflammatory proximal tubular cell state, thereby promoting maladaptive renal repair and the AKI-to-CKD transition.

    External validation of postnatal gestational age estimation using newborn metabolic profiles in Matlab, Bangladesh

    Malia SQ Murphy et al.
    Gestational age estimation models derived from newborn screening bloodspot samples are effective on data obtained from both heel prick and cord blood samples in low-resource settings.

    Inflammation-induced IgE promotes epithelial hyperplasia and tumour growth

    Mark David Hayes et al.
    Natural IgE supports epithelial cell growth and differentiation in healthy skin, but during chronic tissue inflammation, IgE drives tumour outgrowth of epithelial cells harbouring oncogenic mutations.

    Maintenance of age in human neurons generated by microRNA-based neuronal conversion of fibroblasts

    Christine J Huh et al.
    MicroRNA-based direct conversion of human fibroblasts to neurons is applicable to fibroblasts from donors ranging in age from neonatal to centenarian, allowing the generation of neurons that maintain the age-associated signatures of the starting fibroblasts.

    Phosphodiesterase 4D acts downstream of Neuropilin to control Hedgehog signal transduction and the growth of medulloblastoma

    Xuecai Ge et al.
    Neuropilin integrates with Hedgehog signal transduction by a newly identified transducer to control cerebellar neurogenesis and medulloblastoma.

    How IGF-1 activates its receptor

    Jennifer M Kavran et al.
    Ligand binding to the ectodomain of the insulin-like growth factor receptor destabilises an autoinhibitory inter-subunit interaction, which allows the transmembrane domains to associate and the intracellular regions to autophosphorylate.
