(neuroscience)
A small membrane-bound structure in the axon terminals of nerve cells that contains neurotransmitters and releases them by exocytosis when an action potential reaches the terminal.

These findings suggest that TEN also increased action potential-independent neurotransmitter release from the presynaptic terminals of Schaffer collateral-CA1 synapses (Sun and Kapur 2012).
Cdk5/p35 also was indicated inhibits neurotransmitter release through the phosphorylation of P/Q-type voltage-dependent Ca2+ channel and down-regulation of the channel activity (Tomizawa et al.
Subcellular localization suggested a possible role for synapsin III in the regulation of neurotransmitter release and synaptogenesis (14,15).
Recently, 6-OH-BDE-47 (6-hydroxy-2,2',4,4' -tetrabromodiphenyl ether), a hydroxylated metabolite of BDE-47 (2,2',4,4' -tetrabromodiphenyl ether), was demonstrated to increase vesicular neurotransmitter release and [[[Ca.
It is thought that G[alpha]o modulates calcium channels and inhibits presynaptic neurotransmitter release.
PKC plays major roles in the regulation of neuronal excitability, neuroplasticity, and neurotransmitter release.
When activated, these receptors inhibit neurotransmitter release via mechanisms that involve inhibition of voltage-gated calcium channels whose function is necessary for proper release.
Since synapsin is a neuronal phosphorprotein involved in the regulation of neurotransmitter release, the binding of anti-gliadin antibodies to synapsin may reveal clues about the potential pathogenic roles of the antibody and its association with extra-intestinal complications.
Stimulation of the hair bundle, as we have seen, causes membrane depolarization, neurotransmitter release, and action potential discharges in auditory nerve fibers.
It's not yet known whether shifts in electrical activity similarly influence neurotransmitter release throughout embryonic nervous systems or in adult neurons.
When protons bind to photoreceptor calcium channels, the voltage activation range of the channels shifts to more depolarized potentials and the overall conductance of the cell to calcium is reduced, which significantly reduces neurotransmitter release (3).
BDNF is one of the most potent factors that encourages nerve tissue survival and regulates neurotransmitter release and nerve growth.
