Synaptic vesicles are the characteristic organelles of the presynaptic nerve terminals of chemical synapses (i.e., those utilizing the release of a specific chemical transmitter substance to bring about synaptic transmission). They are normally 45–50 nm in diameter and must be among the most homogeneous and uniform lipoprotein membrane organelles known.

Neurotransmitter release from presynaptic nerve endings is mediated by Ca2+-dependent exocytosis of synaptic vesicles. During the past 15 years, major progress has been made in unravelling the molecular mechanisms underlying exocytosis and the recycling of synaptic vesicles.

Synaptic Vesicle Phosphoproteins and Regulation of Synaptic Function
Science, 1993Complex brain functions, such as learning and memory, are believed to involve changes in the efficiency of communication between nerve cells. Therefore, the elucidation of the molecular mechanisms that regulate synaptic transmission, the process of intercellular communication, is an essential step toward understanding nervous system function.

Annual Review of Neuroscience, 2004
▪ Abstract Neurotransmitter release is mediated by exocytosis of synaptic vesicles at the presynaptic active zone of nerve terminals. To support rapid and repeated rounds of release, synaptic vesicles undergo a trafficking cycle. The focal point of the vesicle cycle is Ca2+-triggered exocytosis that is followed by different routes of endocytosis and ...

Synaptic vesicle life cycle and synaptic turnover
Journal of Physiology-Paris, 1993Cholinergic synaptic vesicles contain a mixture of soluble low molecular mass constituents. Besides acetylcholine these include Ca2+, ATP, GTP, small amounts of ADP and AMP, and also the diadenosine polyphosphates Ap4A and Ap5A. In synaptic vesicles isolated from the electric ray these diadenosine polyphosphates occur in mmol concentrations and might ...

On synaptic vesicles, complex vesicles and dense projections
Brain Research, 1970Observations support the view that in vertebrates synaptic vesicles are produced by liberation from complex vesicles, which in turn are derived from the membranes of the presynaptic bag. Some of the shell fragments of the complex vesicles remain in the bag, whereas other fragments of the shell adhere to the wall of the synaptic vesicle. It is suggested

Controversies in synaptic vesicle exocytosis
Journal of Cell Science, 2003At the heart of synaptic transmission resides the synaptic vesicle cycle - a membrane trafficking pathway in which small membrane-bound vesicles mediate the release of neurotransmitter from presynaptic terminals.

Mechanisms of Synaptic Vesicle Exocytosis
Annual Review of Cell and Developmental Biology, 2000▪ Abstract Chemical synaptic transmission serves as the main form of cell to cell communication in the nervous system. Neurotransmitter release occurs through the process of regulated exocytosis, in which a synaptic vesicle releases its contents in response to an increase in calcium.

Ultrastructure of the Membrane of Synaptic Vesicles
Nature, 1967INVESTIGATIONS by Whittaker and Sheridan1 on permanganate fixed preparations of isolated synaptic vesicles have recently confirmed that the membrane of such organelles has the structure of a “unit membrane”2, but have also indicated that in this case the classical model should be corrected in order to take into account the results obtained on negative ...

Synapsins and Synaptic Vesicle Storage
2014The synapsins constitute a family of evolutionarily conserved neuronal phosphoproteins associated with the cytosolic surface of synaptic vesicles. In mammals, the family comprises three members encoded by distinct genes that give rise to various splicing isoforms.
