    The LRRK2 G2019S mutation alters astrocyte-to-neuron communication via extracellular vesicles and induces neuron atrophy in a human iPSC-derived model of Parkinson’s disease

    Aurelie de Rus Jacquet, Jenna L Tancredi ... Erin K O'Shea
    Extracellular vesicles are proposed as novel, non-cell-autonomous mediators of neuronal atrophy in Parkinson's disease.

    Formin-like 1β phosphorylation at S1086 is necessary for secretory polarized traffic of exosomes at the immune synapse in Jurkat T lymphocytes

    Javier Ruiz-Navarro, Sara Fernández-Hermira ... Manuel Izquierdo Pastor
    FMNL1β is phosphorylated on S1086 in a protein kinase C δ (PKCδ)-dependent manner and S1086-phosphorylated FMNL1β acts downstream of PKCδ to regulate centrosome and multivesicular bodies polarization to the immunological synapse and exosome release.

    Ribosome subunit attrition and activation of the p53–MDM4 axis dominate the response of MLL-rearranged cancer cells to WDR5 WIN site inhibition

    Gregory Caleb Howard, Jing Wang ... William P Tansey
    Analysis of the action of WDR5 inhibitors in leukemia cells reveals decreased ribosome inventory, impaired protein synthesis, induction of nucleolar stress, and activation of p53 via alternative splicing of MDM4.

    GLI1 facilitates collagen-induced arthritis in mice by collaborative regulation of DNA methyltransferases

    Gaoran Ge, Qianping Guo ... Dechun Geng
    A new role is identified for GLI1 in modulating the inflammatory response of macrophages and the overaction of osteoclasts in collagen-induced arthritis by collaboratively regulating DNMT1 and DNMT3a.

    Site-specific glycosylation regulates the form and function of the intermediate filament cytoskeleton

    Heather J Tarbet, Lee Dolat ... Michael Boyce
    The in vivo modification of the canonical intermediate filament protein vimentin with O-linked beta-N-acetylglucosamine affects its function in filament assembly, cell migration and host-pathogen interactions.
