    Recruitment of clathrin to intracellular membranes is sufficient for vesicle formation

    Cansu Küey, Méghane Sittewelle ... Stephen J Royle
    Clathrin-coated vesicles can be made to form on intracellular membranes using a minimal molecular system, which defines the core vesicle budding machinery.

    Calcium dependence of neurotransmitter release at a high fidelity synapse

    Abdelmoneim Eshra, Hartmut Schmidt ... Stefan Hallermann
    The Ca2+-dependence of vesicle priming, fusion, and replenishment at cerebellar mossy fiber boutons show a prominent Ca2+-dependent priming step, a shallow non-saturating dose-response curve up to 50 µM, and little Ca2+-dependence of sustained vesicle replenishment.

    Pulsed ultrasound promotes secretion of anti-inflammatory extracellular vesicles from skeletal myotubes via elevation of intracellular calcium level

    Atomu Yamaguchi, Noriaki Maeshige ... Hidemi Fujino
    Ultrasound promotes release of extracellular vesicles from cultured myotubes and elicits anti-inflammatory effects on macrophages, indicating the potential of ultrasound stimulation to muscle for anti-inflammatory purposes.

    A synaptic F-actin network controls otoferlin-dependent exocytosis in auditory inner hair cells

    Philippe FY Vincent, Yohan Bouleau ... Didier Dulon
    A synaptic F-actin network tightly controls the flow of synaptic vesicles during exocytosis at the inner hair cell ribbons.

    A polarity pathway for exocyst-dependent intracellular tube extension

    Joshua Abrams, Jeremy Nance
    Lumen extension in intracellular tubes relies on a molecular pathway involving Rho GTPase signaling, cell polarity, and vesicle-tethering proteins.

    A role of OCRL in clathrin-coated pit dynamics and uncoating revealed by studies of Lowe syndrome cells

    Ramiro Nández, Daniel M Balkin ... Pietro De Camilli
    Studies of Lowe syndrome patient cells, which lack the inositol 5-phosphatase OCRL, suggest that a defect in endocytosis plays a role in the pathological manifestations of the disease.

    Prominin 1 and Tweety Homology 1 both induce extracellular vesicle formation

    Tristan A Bell, Bridget E Luce ... Luke H Chao
    Prominin 1 and Tweety Homology 1, two proteins that regulate membrane shape in neural and neuroepithelial cells, have shared evolutionary history and both cause cells to secrete extracellular vesicles.

    Myristoylated Neuronal Calcium Sensor-1 captures the preciliary vesicle at distal appendages

    Tomoharu Kanie, Roy Ng ... Peter K Jackson
    Neuronal Calcium Sensor-1 (NCS1) is a protein that captures the preciliary vesicle in the early step of the cilium formation.

    A quantitative approach for analyzing the spatio-temporal distribution of 3D intracellular events in fluorescence microscopy

    Thierry Pécot, Liu Zengzhen ... Charles Kervrann
    QuantEv is a fully automatic and semi-parametric method that allows quantitative analysis of the spatio-temporal distribution of complex molecular trafficking objects at the scale of the whole cell.

    Clathrin-independent pathways do not contribute significantly to endocytic flux

    Vassilis Bitsikas, Ivan R Corrêa Jr, Benjamin J Nichols
    Chemical labelling of all primary endocytic vesicles allows the contribution of different endocytic mechanisms to the total endocytic uptake in cultured mammalian cells to be quantified.
