One of the proteins that has a crucial role in this secretion event is synaptotagmin i, an abundant constituent of synaptic vesicles that binds ca2+ ions through two c2 domains. The presynaptic membrane releases neurotransmitter by exocytosis.
Which Of These Ions Triggers Exocytosis Of Synaptic Vesicles. The role of cholesterol in synaptic vesicles exocytosis might be because of a direct modulation of membrane properties such as membrane curvature. Thus, calcium ions trigger the process called exocytosis whereby a fusion pore is temporarily created to allow the release of neurotransmitters into the synaptic cleft. When calcium ions enter the synaptic terminal, they cause vesicles containing neurotransmitter molecules to fuse to the plasma membrane of the sending neuron. It contains synaptic vesicles with neurotransmitters that send messages to the axon�s target.

Synaptic vesicle exocytosis at ribbon synapses is also initiated by influx of ca 2+ through vgcc. Thus, calcium ions trigger the process called exocytosis whereby a fusion pore is temporarily created to allow the release of neurotransmitters into the synaptic cleft. When neurotransmitter molecules bind to receptors in the plasma membrane of the receiving neuron, These two papers [40 ,41 ] demonstrate that synaptotagmin, a synaptic vesicle protein considered to be a likely candidate for the ca2+ sensor of synaptic exocytosis, is also important for membrane retrieval and vesicle recycling following exocytosis.
What triggers synaptic vesicle release?
Synaptic vesicle release is highly regulated, not only in the coupling of exocytosis to membrane depolarization and cal� influx, but also in the amount of neurotransmitter released per membrane depolarization. Synaptic vesicle exocytosis at ribbon synapses is also initiated by influx of ca 2+ through vgcc. The role of cholesterol in synaptic vesicles exocytosis might be because of a direct modulation of membrane properties such as membrane curvature. Binding of the neurotransmitter to the receptor triggers a postsynaptic response specific for that receptor. When calcium ions enter the synaptic terminal, they cause vesicles containing neurotransmitter molecules to fuse to the plasma membrane of the sending neuron. Ca 2+ triggers synaptic vesicle exocytosis, thereby releasing the neurotransmitters contained in the vesicles and initiating synaptic transmission.
