    A Fyn biosensor reveals pulsatile, spatially localized kinase activity and signaling crosstalk in live mammalian cells

    Ananya Mukherjee et al.
    Unique biosensor design and protein-engineering enables direct visualization of the active form of Fyn kinase with high specificity, minimal perturbation and shows cellular signaling to be compartmentalized and pulsatile.

    Endothelial heterogeneity across distinct vascular beds during homeostasis and inflammation

    Ankit Jambusaria et al.
    Vascular endothelial cells in the brain, heart and lung exhibit tissue-specific heterogeneity and plasticity, expressing genes that were traditionally thought to be only expressed by the surrounding parenchymal tissue cells.

    TrpML-mediated astrocyte microdomain Ca2+ transients regulate astrocyte–tracheal interactions

    Zhiguo Ma, Marc R Freeman
    Astrocyte microdomain calcium transients are mediated by TrpML, stimulated by ROS and tyramine, and mediate astrocyte–tracheal interactions in CNS gas exchange.

    Islet vascularization is regulated by primary endothelial cilia via VEGF-A-dependent signaling

    Yan Xiong et al.
    Primary cilia on endothelial cells are required for VEGF-A/ VEGFR2-dependent signaling, islet vascularization and, consequently, nutrient delivery and insulin disposal.

    Cholesterol accessibility at the ciliary membrane controls hedgehog signaling

    Maia Kinnebrew et al.
    The patched hedgehog receptor inhibits the transmembrane transducer smoothened by reducing the accessibility of cholesterol locally at the membrane of the primary cilium.

    An integrin/MFG-E8 shuttle loads HIV-1 viral-like particles onto follicular dendritic cells in mouse lymph node

    Chung Park, John H Kehrl
    Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.

    Dendritic NMDA receptors in parvalbumin neurons enable strong and stable neuronal assemblies

    Jonathan H Cornford et al.
    NMDA receptors on PV+ interneurons mediate supralinear integration at feedback synapses from local pyramidal neurons, enabling competing networks to ‘lock’ onto salient inputs.

    Drosophila macrophages switch to aerobic glycolysis to mount effective antibacterial defense

    Gabriela Krejčová et al.
    Activated Drosophila macrophages undergo transient metabolic remodeling towards Hypoxia inducible factor 1 α-driven aerobic glycolysis, a program that induces systemic metabolic changes and is crucial for resistance to infection.

    The transcription factor Hey and nuclear lamins specify and maintain cell identity

    Naama Flint Brodsly et al.
    Hey together with LaminC continuously supervise nuclear organisation and differentiated enterocyte identity, a regulation that is lost upon ageing, resulting in loss of gut homeostasis.

    A conserved Mcm4 motif is required for Mcm2-7 double-hexamer formation and origin DNA unwinding

    Kanokwan Champasa et al.
    Analysis of an essential motif in Mcm4 provides insights into replicative helicase double-hexamer formation and the first step requiring this intermediate during replication initiation.
