自噬对胰岛β细胞保护作用研究进展

Protective effect of autophagy on pancreatic β cells:research advances

糖尿病的发生与胰岛素分泌异常密切相关。胰岛β细胞数量减少或功能缺陷直接影响胰岛素分泌。自噬是一个高度保守的过程,它能改善炎症、氧化应激和内质网应激等对β细胞功能的损伤,延缓糖尿病的病程。本文将从自噬的定义、自噬相关蛋白和信号调节通路、自噬在维持胰岛β细胞结构和功能中的作用,以及影响胰岛β细胞自噬的主要因素等方面进行综述。

The development of diabetes is associated with parasecretion of insulin resulting from the mass loss and dysfunction of β-cell in pancreas. Autophagy is a process of high conservation, which can improve β-cell function impaired by inflammation, oxidative stress, and endoplasmic reticulum stress. That is beneficial to delaying the progression of diabetes. Thus, in this review we summarize the definition of autophagy, autophagy related proteins and modulation of autophagy signaling pathways, the protection of autophagy on the structure and function of β-cells, as well as autophagy in β-cells with inflammation, oxidative stress and endoplasmic reticulum stress.
