WebSynaptic vesicles - definition. sac-like structures in neurons that store neurotransmitter molecules before releasing them into the synapse in response to electrical signaling … WebPrevious studies have suggested that SNAP-29 inhibits SNARE complex disassembly, thereby reducing synaptic transmission in cultured superior cervical ganglion neurons in an activity-dependent manner. However, the role of SNAP-29 in regulating synaptic vesicle recycling and short-term plasticity in the central nervous system remains unclear.
