The synaptic vesicles

WebSynaptic vesicles are locally recycled following exocytosis and rapidly refilled with neurotransmitter from the cytoplasm by a process that depends on the electrochemical gradient generated by a proton pump. Little is known about the molecules that import neurotransmitter into synaptic vesicles. Websynaptic vesicles. Although the membrane of a "resting" neuron is highly permeable to potassium ions, its membrane potential does not exactly match the equilibrium potential …

WebSynaptic vesicle replenishment was also enhanced. Furthermore, stimulated emission depletion microscopy suggested an increase in the numbers of Munc13-1 and RIM1 molecules within active zones. We propose that dynamic changes in the active zone components may be relevant for the increased fusion competence and synaptic vesicle … The synaptic vesicle cycle The events of the synaptic vesicle cycle can be divided into a few key steps: 1. Trafficking to the synapse Synaptic vesicle components are initially trafficked to the synapse using members of the kinesin motor family. In C. elegans the major motor for synaptic vesicles is UNC-104.
