摘要
自噬是一种必不可少的分解代谢机制,可将错误折叠的蛋白质和受损的细胞器传递至溶酶体进行降解。自噬途径包括宏观自噬,伴侣介导的自噬和微自噬,每种途径都涉及底物向溶酶体的不同传递机制。这些途径的缺陷以及由此产生的蛋白质聚集体的积累代表了神经退行性疾病例如阿尔茨海默氏症,帕金森氏症和亨廷顿病的常见病理生物学特征。这篇综述总结了最相关的遗传和实验证据,显示了自噬在帕金森氏病(PD)中的作用,这些证据表明该过程如何促进疾病的发病机理。考虑到溶酶体参与自噬过程的最后一步,还将讨论溶酶体缺陷在自噬损害中的作用及其对疾病的影响。将包括对非神经自噬在PD发病机理中的作用的一瞥。此外,我们将研究新的药理学靶点和治疗策略,它们通过促进自噬在理论上可能对PD有益。特别关注的是天然产物,例如酚类化合物,由于其潜在的功效以及较低的毒性,它们正受到越来越多的关注。尽管已做出许多努力阐明自噬过程,但新的治疗性干预措施的开发需要对可能导致PD自噬缺陷的机制有更深入的了解,并应考虑到该疾病的多因素性质以及其表型异质性。 PD患者。
