自噬是一种高度保守的细胞内分解代谢途径,降解细胞内的长寿命蛋白质和细胞器。作为细胞生存机制,自噬通常会响应营养剥夺和其他应激而被激活。越来越多的证据表明,自噬除了维持肝脏能量和营养平衡外,在肝脏病理生理学中起着关键作用。饮酒引起肝脏代谢变化、氧化应激、脂滴积聚和线粒体损伤,这些都可以通过自噬来调节。本文综述了自噬在酒精性肝病中的作用和机制,以及通过调节自噬治疗酒精性肝病的可能性。
Autophagy is a highly conserved intracellular catabolic pathway that degrades cellular long-lived proteins and organelles. Autophagy is normally activated in response to nutrient deprivation and other stresses as a cell survival mechanism. Accumulating evidence indicates that autophagy plays a critical role in liver pathophysiology, in addition to maintain hepatic energy and nutrient balance. Alcohol consumption causes hepatic metabolic changes, oxidative stress, accumulation of lipid droplets and damaged mitochondria, all of these can be regulated by autophagy. This review summarizes the recent findings about the role and mechanisms of autophagy in alcoholic liver disease, and the possible intervention for treating alcoholic liver disease by modulating autophagy.
