    Modeling of axonal endoplasmic reticulum network by spastic paraplegia proteins

    Belgin Yalçın, Lu Zhao ... Cahir J O'Kane
    Proteins of the reticulon and REEP families, homologous to the products of human Hereditary Spastic Paraplegia disease genes, contribute to shaping and continuity of the axonal endoplasmic reticulum network in Drosophila.

    Structural plasticity of dendritic secretory compartments during LTP-induced synaptogenesis

    Yelena D Kulik, Deborah J Watson ... Kristen M Harris
    The secretory and recycling components of neuronal dendrites, smooth endoplasmic reticulum and endosomes, were discovered to support synaptogenesis underlying a cellular mechanism of learning and memory in the developing brain.

    STIM1-dependent peripheral coupling governs the contractility of vascular smooth muscle cells

    Vivek Krishnan, Sher Ali ... Scott Earley
    STIM1 regulates the contractility of blood vessels and blood pressure by organizing membrane contact sites and ion channel activity in vascular smooth muscle cells in a manner that is independent of its canonical function in store-operated Ca2+entry.

    Interleukin-33 regulates the endoplasmic reticulum stress of human myometrium via an influx of calcium during initiation of labor

    Li Chen, Zhenzhen Song ... Guoying Zhang
    IL-33 plays an important role in the initiation of labor by leading to stress of the ER via an influx of calcium ions in human uterine smooth muscle cells.

    Fluid mechanics of luminal transport in actively contracting endoplasmic reticulum

    Pyae Hein Htet, Edward Avezov, Eric Lauga
    The viscous hydraulics of contracting endoplasmic reticulum networks challenge common solute transport theories, suggesting the contraction of peripheral sheets as a plausible driving mechanism.

    ATP activation of peritubular cells drives testicular sperm transport

    David Fleck, Lina Kenzler ... Marc Spehr
    Purinergic signaling controls mammalian sperm transport.

    Membrane estrogen receptor alpha (ERα) participates in flow-mediated dilation in a ligand-independent manner

    Julie Favre, Emilie Vessieres ... Daniel Henrion
    A new pathway is described involving the estrogen receptor alpha in the acute response of small arteries to flow independent of the ligand (estrogen) and of the nuclear signaling.

    Single-cell transcriptomics of vomeronasal neuroepithelium reveals a differential endoplasmic reticulum environment amongst neuronal subtypes

    GVS Devakinandan, Mark Terasaki, Adish Dani
    Developmental specialization of vomeronasal sensory neurons involves selective upregulation of endoplasmic reticulum genes in a subset of neurons along with a hypertrophic gyroid membrane architecture.

    Proteomic mapping of cytosol-facing outer mitochondrial and ER membranes in living human cells by proximity biotinylation

    Victoria Hung, Stephanie S Lam ... Alice Y Ting
    One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.

    Arteries: STIMulating blood pressure

    Tessa AC Garrud, Jonathan H Jaggar
    The protein STIM1 helps to maintain membrane coupling sites in smooth muscle cells that regulate arterial contractility and blood pressure.
