Various approaches for measurement of synaptic vesicle endocytosis at the central nerve terminal

초록

At the presynaptic terminal, neurotransmitters are stored in synaptic vesicles (SVs), which are released and recycled via exo- and endocytosis. SV endocytosis is crucial for sustaining synaptic transmission by maintaining the SV pool. Many studies have shown that presynaptic dysfunction, particularly impairment of SV endocytosis, is related to neurological disorders. Notably, the presynaptic terminal is considered to be a sensitive structure because certain presynaptic dysfunctions, manifested as impaired SV endocytosis or ultrastructural changes in the presynaptic terminal, can be observed before there is a biochemical or pathological evidence of a neurological disorder. Therefore, monitoring and assessing the presynaptic function by SV endocytosis facilitates the development of early markers for neurological disorders. In this study, we reviewed the current methods for assessing and visualizing SV endocytosis at the central nerve terminal.
