Synaptic vesicle endocytosis dysfunction potentially mediate dopaminergic neurodegeneration through intersections with various pathway. Mutations in the PD-related genes or SVE-related genes reviewed in this article may cause damage to the endocytosis of vesicles at the terminal axons of neurons. SVE may interact with synaptic transmission, autophagy and mitochondrial autophagy, and the endolysosomal system has the effect of this two-way condition. These pathways can lead to the accumulation and spread of misfolded proteins with axon degeneration or neurotoxicity, and ultimately lead to the pathogenesis of PD. Among them, regarding the relationship between SVE and lipid raft synthesis and metabolism, the mechanism of abnormal lipid raft metabolism leading to the pathogenesis of PD deserves more research and attention. PD, Parkinson’s disease; SVE, synaptic vesicle endocytosis.
