Annual Review of Neuroscience, 1996
Synaptic vesicle exocytosis is rapid and highly localized, which are features that arise from the organization of the presynaptic active zone, where vesicle fusion occurs. Colocalization of calcium channels with the proteins making up the vesicle docking machinery at the active zone, combined with the low affinity and high cooperativity of the calcium ...

Synaptotagmin and neurotransmitter release
Cell, 1993William M. DeBello,’ Heinrich Bet Torri-Tarelli et al., 1985), and that this exocytosis is trig- gered by a rise in the concentration of Ca within presynap- tic terminals (Miledi, 1973). The source of this triggering Ca is the voltage-gated Ca channel, which is found in close proximity to the sites of exocytosis (Augustine et al., 1987).

Mechanisms of Neurotransmitter Release
International Review of Neurobiology, 1999Publisher Summary This chapter focuses on the mechanism of neurotransmitter release. The primary form of intercellular communication within the nervous system is mediated by chemical transmission at synapses. Upon propagation of an action potential into the nerve terminal, there is an influx of Ca2+ through voltage-activated Ca2+ channels, which ...

Neurons send out a multitude of chemical signals, called neurotransmitters, to communicate between neurons in brain, and between neurons and target cells in the periphery. The most important of these communication processes is synaptic transmission, which accounts for the ability of the brain to rapidly process information, and which is characterized ...

Uptake and Release of Neurotransmitters
Current Protocols in Neuroscience, 1998AbstractThe availability of clonal cell lines for norepinephrine, dopamine, and serotonin transporters allows the characterization of drug interactions with transporter recognition sites using radioligands, as well as the characterization of drug effects on selective transporter‐mediated uptake and release of substrate. In addition to clonal cell lines,

Cytoskeleton dynamics during neurotransmitter release
Trends in Neurosciences, 1993It has become apparent in recent years that the cytoskeleton and its associated proteins play a major role in secretion. This review summarizes recent findings on the cytoskeleton organization and the molecular topology of its regulatory proteins, as well as the dynamic changes that occur in this organelle during secretion from neurons and secretory ...

Synaptotagmins: Beyond Presynaptic Neurotransmitter Release
The Neuroscientist, 2019Synaptotagmins (Syts) are well-established primary Ca2+ sensors to initiate presynaptic neurotransmitter release. They also play critical roles in the docking, priming, and fusion steps of exocytosis, as well as the tightly coupled exo-endocytosis, in presynapses.

Airway nerves: neurotransmitter release
Current Opinion in Pharmacology, 2002A number of methods exist that allow one to study the pharmacology of neuropeptide release in the airways. Methods include in vitro organ bath techniques to measure neuropeptide release functionally as changes in smooth-muscle tone and direct measurement of neuropeptide release from airway tissue or cultured sensory neurones. The measurement of sensory

Neurotransmitter release at rapid synapses
Biochimie, 2000The classical concept of the vesicular hypothesis for acetylcholine (ACh) release, one quantum resulting from exocytosis of one vesicle, is becoming more complicated than initially thought. 1) synaptic vesicles do contain ACh, but the cytoplasmic pool of ACh is the first to be used and renewed on stimulation.
