Abstract:
The core pathological feature of Parkinson's disease(PD)is the abnormal aggregation of α-synuclein and the result ing neuronal damage.α-Synuclein exhibits toxic effects when it forms oligomers or fibrils,leading to neuronal death via multiple pathways,including mitochondrial dysfunction,impaired vesicular trafficking,dopamine auto-oxidation,and neuroinflammation.In addition,α-synuclein can propagate between cells via exosomes,endocytosis/exocytosis,tunneling nanotubes,or vagal nerve axonal transport,creating a cascade of pathological effects.Animal models of PD that recapitulate the key pathological hallmark of α-synuclein accumulation are indispensable tools for elucidating disease mechanisms and developing novel therapeutic interventions.To date,various strategies,including transgenic techniques,bacterial artificial chromosome(BAC)-mediated expression,viral vector-mediated overexpression,and gene editing,have been employed to develop α-synuclein overexpression animal models.These models have significantly advanced our exploration of the relationship between PD and α-synuclein.This systematic review considers the structure and function of α-synuclein,its mechanisms of toxicity,intercellular propagation pathways,animal models of overexpression,and potential therapeutic targets based on its pathogenic mechanisms.
