自身免疫性疾病治疗的新靶点

New Target of Treatment of Autoimmune Diseases

临床治疗自身免疫性疾病主要靠免疫抑制剂,但大量使用免疫抑制剂会引起迟发性的功能异常、感染、肿瘤等不良反应,因此诱导机体免疫耐受和抑制免疫应答是最有效的方法。树突状细胞(DC)是迄今发现的功能最强的专职抗原提呈细胞。一方面,DC作为专职抗原递呈细胞触发和调节固有性及获得性免疫反应,启动免疫应答;另一方面,DC通过多种机制诱导抗原特异性T细胞无能,且在免疫耐受中展示出极强的可塑性,在机体免疫调节中起重要作用。核因子(NF)-κB是细胞内的一种核转录因子,树突状细胞内的NF-κB对其自身的调节包括DC的发育、成熟、抗原提呈、刺激T细胞发生免疫应答功能等方面,这些调节在自身免疫性疾病的发病机制中起重要作用,将成为自身免疫性疾病治疗的新靶点。

On the clinic,the main treatment of autoimmune diseases were used immunosuppressant,but large-scale use of immunosuppressive agents could cause of the delayed dysfunction,side effects such as infection,tumors and so on,so-induced immune suppression and immune tolerance response was the most effective way.So far,dendritic cells(DC) was the most powerful professional antigen-presenting cells.On one hand,DC as a full-time antigen-presenting cells and trigger regulation of the inherent and acquired immune respo...
