中文摘要：

长期以来，人们对维生素D的认识主要集中在对钙磷骨代谢的调节。自1980年，人们在钙磷骨代谢相关细胞外，如甲状旁腺细胞、淋巴细胞、胸腺及前髓细胞等发现了维生素D受体后，对维生素D的认识进一步开阔，后期的研究结果显示维生素D除了调节钙磷骨代谢之外，还具有更广泛的生理功能，其作用主要包括：参与免疫调节；参与炎性反应；糖、脂代谢的调节等病理生理过程。近年来，维生素D对免疫系统的调节作用备受关注。本文就维生素D对免疫系统的调节作用作一综述。

英文摘要：

For a long time, the studies on function of vitamin D are concentrated on the regulation of calcium-phosphate and bone metabolism. Since vitamin D receptors were discovered in sparathyroid cells, lymphocytes, thymus, and promyelocytic cells in 1980, the knowledge of vitamin D has been broadened. Biside regulation of calcium-phosphate and bone metabolism, a wide range of physiological roles are expouded by the subsequent studies, which mainly include immune regulation, inflammatory response,and regulation of glucose and lipid metabolism. Recently,the effects of vitamin D on regulation of immunity attract dramatic attention. This paper summarizes the roles of vitamin D in regulation of immunity.
