自噬流调控在白内障眼病中的研究进展

Research progress on autophagic flux regulation in cataract

摘要:

自噬流(autophagic flux)是指自噬双层膜形成、自噬体形成、自噬溶酶体形成、自噬溶酶体降解的一系列动态过程。白内障的病因较为复杂，包括基因突变引起的晶状体先天发育异常、衰老引起的氧化损伤、糖尿病引起的糖代谢异常以及术后炎症因子刺激导致晶状体上皮细胞(LECs)增生等因素，都与白内障的形成有关。近年来，越来越多的研究发现自噬流调控可通过改变LECs的状态，参与白内障的病理生理过程。因此，为了系统地了解自噬流调控对白内障眼病的影响，本文对其展开综述。

Abstract:

Autophagic flux refers to a series of dynamic process of autophagic bilayer membrane formation, autophagosome formation, autophagolysosomes formation and degradation. The etiology of cataract is complex, including congenital abnormalities in lens development due to genetic mutations, oxidative damage due to aging, abnormalities in glucose metabolism due to diabetes, and proliferation of lens epithelial cells(LECs)stimulated by postoperative inflammatory factor, all of which are associated with the development of cataracts. A growing number of research in recent years have discovered that altering the status of LECs can contribute to the pathophysiological process of cataract by regulating autophagic flux. This review summarized the impacts of autophagic flux regulation on cataract.
