How Are Synaptic Vesicle Exocytosis and Endocytosis Affected in Parkinson Disease? - PubMed Synaptic vesicle exocytosis and endocytosis are 2 fundamental processes that involve the coordinated and timely activity of many proteins and protein-lipid interactions. Alpha-synuclein (α-Syn) regulates several steps of these processes. Impaired exocytosis and endocytosis are important consequences …
