摘要: Toll样受体(Toll like receptors,TLRs)是一类跨膜受体,主要表达于抗原提呈细胞及一些上皮细胞,通过识别特异性配体来激活免疫反应。除外源性配体外,TLRs还可识别一些内源性分子,信号的过度活化则可导致自身免疫性疾病。本文综述了TLRs的种类及配体、相应的信号通路及功能调节,重点介绍了TLRs在一些自身免疫性疾病中的研究现状,最后探讨了TLRs在自身免疫性疾病治疗中的作用。

Abstract: Toll like receptors(TLRs) are a class of transmembrane receptors. They are expressed mainly in antigen presenting cells as well as epithelial cells, and can activate immune reaction by recognizing specific ligands. Besides exogenous ligands, TLRs can also recognize some of the endogenous ligands. Overactivation of TLRs' endogenous signal will induce autoimmune diseases. In this review, we summarize the types of TLRs and their ligands, and discuss the TLRs pathways and functional regulation. We focus on the recent researches about the association of TLRs with some autoimmune diseases, and prospectively discuss the roles of TLRs in the therapy of these diseases.

Key words: Toll like receptors, signal pathway, autoimmune disease, therapy
