    Optical detection of three modes of endocytosis at hippocampal synapses

    Natali L Chanaday, Ege T Kavalali
    Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.

    Integrated control of transporter endocytosis and recycling by the arrestin-related protein Rod1 and the ubiquitin ligase Rsp5

    Michel Becuwe, Sébastien Léon
    A novel regulatory step in the endocytic pathway, which occurs post-internalization, takes place at the trans-Golgi network and involves the arrestin-related protein Rod1 and the ubiquitin ligase Rsp5.

    Ca2+ sensor synaptotagmin-1 mediates exocytosis in mammalian photoreceptors

    Justin J Grassmeyer et al.
    The vesicular Ca2+ sensor synaptotagmin-1 regulates both fast phasic and slow tonic glutamate release at ribbon synapses of rod and cone photoreceptor cells.

    Munc18-1-regulated stage-wise SNARE assembly underlying synaptic exocytosis

    Lu Ma et al.
    The Munc18-1 protein promotes formation of the t-SNARE complex and the half-zippered SNARE complex, two rate-limiting steps of SNARE assembly, to enhance membrane fusion.

    Type-I myosins promote actin polymerization to drive membrane bending in endocytosis

    Hetty E Manenschijn et al.
    Monomeric myosins can stimulate growth of actin filaments under load.

    Dynamin phosphorylation controls optimization of endocytosis for brief action potential bursts

    Moritz Armbruster et al.
    The recycling of transmitter vesicles at synapses shows calcium-dependent regulation that depends on the phosphorylation status of an enzyme called dynamin.

    AP2 hemicomplexes contribute independently to synaptic vesicle endocytosis

    Mingyu Gu et al.
    A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.

    Ultrafast endocytosis at Caenorhabditis elegans neuromuscular junctions

    Shigeki Watanabe et al.
    Optogenetics has revealed that synaptic vesicles can be recycled extremely rapidly in nematodes, indicating that existing models for how synapses 'reload' may need to be revised.

    Exophilin-8 assembles secretory granules for exocytosis in the actin cortex via interaction with RIM-BP2 and myosin-VIIa

    Fushun Fan et al.
    Analyses of knockout mice and a biochemical screen of interacting proteins reveal that exophilin-8 forms a large network of protein interactions to efficiently retain secretory granules beneath the plasma membrane for exocytosis.

    Chronic lithium treatment elicits its antimanic effects via BDNF-TrkB dependent synaptic downscaling

    Erinn S Gideons et al.
    The antimanic action of lithium requires BDNF-TrkB signaling coupled with enhanced dynamin-dependent endocytosis of AMPARs as a potential mechanism underlying the therapeutic effects.
