维生素D及维生素D受体(vitamin D receptor，VDR)介导的生物效应参与调节体内多个病理生理过程，包括钙磷代谢、免疫调控、抗炎、抗感染、肿瘤预防等。自噬是真核细胞溶酶体介导的一种分解代谢途径，分为巨自噬、微自噬及分子伴侣介导的自噬3种类型。
The biological effects mediated by vitamin D and vitamin D receptor (VDR) are involved in the regulation of multiple pathophysiologic processes, including calcium phosphorus metabolism, immune regulation, anti-inflammation, anti-infection and cancer prevention, etc. Autophagy is a eukaryotic cell lysosome-mediated catabolic pathway, which is classified into 3 different types: macroautophagy, microautophagy, and chaperone-mediated autophagy.
