背景:目前对于帕金森病的发病机制尚不清楚,相关研究表明α-突触核蛋白、线粒体与帕金森病发病机制密切相关,主要涉及氧化应激、线粒体复合物损伤、钙稳态、线粒体动力学和线粒体质量控制等方面.目的:对帕金森病中α-突触核蛋白与线粒体损伤之间的关系进行综述.方法:第一作者以"帕金森病,线粒体损伤及机制,α-突触核蛋白"为检索词检索中国知网、万方数据库2010-2024年相关文献50余篇;以"Parkinson's disease,Alpha-synuclein,mitochondria,Oxidative stress,Calcium homeostasis,Mitophagy,Mitochondrial dynamics,Mitochondrial protein introduction"为检索词检索PubMed数据库2010-2024年相关文献750余篇,最终纳入70篇文献进行综述.结果与结论:最近研究证实了线粒体功能障碍在帕金森病病理生理学中的重要作用,尤其α-突触核蛋白与线粒体之间的相互作用是帕金森病发病机制中尤为显著的因素.从天然未折叠的α-突触核蛋白开始,最终形成成熟的原纤维的级联事件统称为α-突触核蛋白聚集.聚集产生的毒性在多巴胺能神经元中积累,继而破坏线粒体功能引起帕金森病.因此,α-突触核蛋白与线粒体功能障碍之间这种双向关系的潜在机制可能为帕金森病的病理生理学提供新的见解.
Mechanism of alpha-synuclein in mitochondrial damage induced by Parkinson's disease
BACKGROUND:Currently,the pathogenesis of Parkinson's disease is not clear.Relevant studies have shown that α-synuclein and mitochondria are closely related to the pathogenesis of Parkinson's disease.It mainly involves oxidative stress,mitochondrial complex damage,calcium homeostasis,mitochondrial dynamics and mitochondrial quality control.OBJECTIVE:To review the association between α-synuclein and mitochondrial damage in Parkinson's disease.METHODS:The first author searched more than 50 documents from CNKI and WanFang databases from 2010 to 2024 using the keywords of"Parkinson's disease,mitochondrial damage and mechanism,α-synuclein"in Chinese as well as more than 750 documents from PubMed between 2010 and 2024 using the keywords of"Parkinson's disease,alpha-synuclein,mitochondria,oxidative stress,calcium homeostasis,mitophagy,mitochondrial dynamics,mitochondrial protein introduction"in English.Finally,70 documents were included for review.RESULTS AND CONCLUSION:Recent studies have confirmed the important role of mitochondrial dysfunction in the pathophysiology of Parkinson's disease,and the interaction between α-synuclein and mitochondria is a particularly significant factor in the pathogenesis of Parkinson's disease.The cascade of events that begin with naturally unfolded α-synuclein and eventually form mature fibril is collectively known as α-synuclein aggregation.The toxicity of aggregation accumulates in dopaminergic neurons and then disrupts mitochondrial function,thereby triggering Parkinson's disease.Therefore,the underlying mechanism of this bidirectional relationship between α-synuclein and mitochondrial dysfunction may provide new insights into the pathophysiology of Parkinson's disease.
