随着肠、骨、肾等经典靶器官组织以外的一些组织的特异性维生素D受体的发现 ,维生素D的一些新功能亦逐渐为人们所认识。其中最引人注目的是维生素D的免疫调节功能。维生素D作用于免疫反应的多个环节 ,能够调节T细胞介导的多种自身免疫性疾病。 1 ,2 5 (OH) 2 D3有可能作为一种新型的免疫调节剂达到防治自身免疫性疾病的作用 ,而不致引起广泛的免疫抑制。 With the discovery of specific vitamin D receptors in some tissues other than the classical target organs such as intestine, bone and kidney, some new functions of vitamin D have also been gradually recognized. One of the most notable is the immunomodulatory function of vitamin D. Vitamin D acts on many aspects of the immune response and regulates many autoimmune diseases mediated by T cells. 1, 25 (OH) 2 D3 may serve as a novel immunomodulator to prevent and cure autoimmune diseases without causing extensive immunosuppression.
