    Physiological and pathophysiological control of synaptic GluN2B-NMDA receptors by the C-terminal domain of amyloid precursor protein

    Paula A Pousinha et al.
    The APP intracellular domain (AICD) physiologically regulates synaptic GluN2B-containing NMDA receptor current, a process that could contribute to pathological Alzheimer's disease-related synaptic failure upon increase of AICD levels in adult neurons.

    Synaptotagmin 1 directs repetitive release by coupling vesicle exocytosis to the Rab3 cycle

    Yunsheng Cheng et al.
    Experiments in C. elegans reveal how synaptotagmin and Rab3, the 'yin and yang' of synapses, control whether transmitter vesicles remain docked at the presynaptic membrane or release their contents into the synapse.

    Dopamine receptors reveal an essential role of IFT-B, KIF17, and Rab23 in delivering specific receptors to primary cilia

    Alison Leaf, Mark Von Zastrow
    The mechanism of signaling receptor delivery to primary cilia involves a specific cellular role of a Rab protein that is critical for vertebrate development.

    Optical electrophysiology for probing function and pharmacology of voltage-gated ion channels

    Hongkang Zhang et al.
    Optogenetic tools enable sophisticated measurements of a voltage-gated sodium channel implicated in pain, as well as high-throughput screening of candidate channel blockers.

    The postsynaptic t-SNARE Syntaxin 4 controls traffic of Neuroligin 1 and Synaptotagmin 4 to regulate retrograde signaling

    Kathryn P Harris et al.
    Syntaxin 4 regulates retrograde signaling in the postsynaptic compartment at Drosophila synapses by controlling trafficking of Neuroligin and Synaptotagmin 4 cargo.

    Activity and Ca2+ regulate the mobility of TRPV1 channels in the plasma membrane of sensory neurons

    Eric N Senning, Sharona E Gordon
    Channel activity is a novel regulatory mechanism for channel mobility in the plasma membrane.

    Influenza-virus membrane fusion by cooperative fold-back of stochastically induced hemagglutinin intermediates

    Tijana Ivanovic et al.
    Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.

    Drosophila Synaptotagmin 7 negatively regulates synaptic vesicle release and replenishment in a dosage-dependent manner

    Zhuo Guan et al.
    Drosophila synaptotagmin 7 functions to restrict SV availability and release, but does not act as the Ca2+ sensor mediating the asynchronous release and facilitation remaining in synaptotagmin 1 mutants.

    Agonist-mediated switching of ion selectivity in TPC2 differentially promotes lysosomal function

    Susanne Gerndt et al.
    The lysosomal ion channel TPC2 emerges as an example of an ion channel in which ion selectivity is not fixed but rather agonist-selective.

    Mitochondria supply ATP to the ER through a mechanism antagonized by cytosolic Ca2+

    Jing Yong et al.
    ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.
