自噬是维持细胞正常功能和结构的基本细胞过程。它可以在应激过程中被诱导,并作为细胞生存的适应性反应。正常肾脏对代谢的需求很高,但相对低氧,特别是在髓质和乳头中。损伤或老化会加重代谢紊乱,并激活多种类型肾细胞的自噬。在肾脏,由于活跃的转运机制,肾小管上皮细胞消耗的能量最多,因此最容易受到低氧或低能量状态的损伤。本文就目前对肾小管损伤和修复过程中上皮细胞自噬的生物学功能和分子调控的研究进展作一综述。
Autophagy is a fundamental cellular process that maintains normal function and structure of the cell. It can be induced during stress and serves as an adaptive response for cell survival. Normal kidneys have high metabolic demands yet are relatively hypoxic, especially in the medulla and papilla. Injury or ageing aggravates metabolic perturbation and activates autophagy in many types of renal cells. In the kidney, tubular epithelial cells consume the most energy due to active transport mechanisms and therefore are the most susceptible to injuries from hypoxic or low-energy states. This brief review will summarize current understandings of the biological function and molecular regulation of epithelial autophagy during tubular injury and repair.
