摘要: Toll样受体(toll like receptors,TLRs)能识别病原微生物相关分子模式,募集含有Toll/白介素-1受体(TIR)结构域的接头蛋白分子,通过髓样分化蛋白88(MyD88)依赖性信号传导通路或由β-干扰素TIR结构域衔接蛋白(TRIF)依赖性信号传导通路启动信号传导,继而引发特异性的免疫应答。作者就TLRs的结构特征、分布、配体识别、参与信号传导的接头蛋白分子及介导的信号传导通路的最新研究进展进行综述。

Abstract: Toll like receptors (TLRs) can recognize pathogen-associated molecular patterns and raise the adaptor protein molecules containing toll IL-1 receptor (TIR) domain.Moreover,TLRs can initiate specific immune response through activating signal transduction by the MyD88-dependent pathway or TRIF-dependent pathways.This article summarizes the latest research review on structure features,distribution,ligand recognition,adaptor protein molecules participating in signal transduction and signal transduction pathway of TLRs.

Key words: toll like receptors; TIR domain; signal transduction pathway
