    Rat behavior and dopamine release are modulated by conspecific distress

    Nina T Lichtenberg et al.
    Rat behavior and dopamine release are preferentially modulated by subjective rather than objective evaluation of outcomes in a social setting.

    Fusion pore regulation by cAMP/Epac2 controls cargo release during insulin exocytosis

    Alenka Guček et al.
    Live cell imaging shows that the cAMP-sensor Epac2, a target of major antidiabetic drugs, is central to fusion pore control during insulin granule exocytosis.

    Spatiotemporal dynamics of multi-vesicular release is determined by heterogeneity of release sites within central synapses

    Dario Maschi, Vitaly A Klyachko
    Release site heterogeneity represents a previously unknown level of structural and functional organization within individual active zones in central synapses, which determines the spatiotemporal dynamics of multi-vesicular release.

    RIM is essential for stimulated but not spontaneous somatodendritic dopamine release in the midbrain

    Brooks G Robinson et al.
    Midbrain dopamine neurons use sophisticated secretory machinery to establish specialized sites for action potential-evoked release of dopamine from their cell bodies and dendrites.

    Properties of multivesicular release from mouse rod photoreceptors support transmission of single-photon responses

    Cassandra L Hays et al.
    To improve the reliability of transmitting small single-photon voltage responses, rod photoreceptor cells release synaptic vesicles in regularly timed multivesicular events that are exquisitely sensitive to small voltage changes.

    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.

    Release-dependent feedback inhibition by a presynaptically localized ligand-gated anion channel

    Seika Takayanagi-Kiya et al.
    An anion-selective ligand gated channel acts as a presynaptic auto-receptor to modulate vesicle release and neuronal excitation.
    1. Neuroscience

    Incomplete vesicular docking limits synaptic strength under high release probability conditions

    Gerardo Malagon et al.
    The probability of occupancy of individual synaptic release sites at rest sets an upper limit to synaptic output when increasing action potential related calcium entry.

    Connexin-43-dependent ATP release mediates macrophage activation during sepsis

    Michel Dosch et al.
    Autocrine activation of macrophages is modulated by Connexin-43-mediated ATP release in response to TLR-4 and -2 agonists in a P2Y1-dependent manner, ultimately determining sepsis survival.

    Release probability increases towards distal dendrites boosting high-frequency signal transfer in the rodent hippocampus

    Thomas P Jensen et al.
    Excitatory synapses that occur further away from the postsynaptic cell soma exhibit greater neurotransmitter release probability, which appears to improve signal transfer fidelity for high-frequency afferent firing.
