摘要 TLR(Toll-like recepter)家族成员以胞内区高度进化保守的TIR结构域(Toll/IL-1R domain)为特征,可通过胞外区的亮氨酸重复序列(leucine-rich repeat,LRR)功能区识别各种病原体相关分子模式(pathogen associated molecular pattern,PAMP)引发机体免疫应答。TLR识别配体后由MyD88、Mal、TRIF、TRAM等含TIR的接头蛋白介导,通过MyD88依赖途径或MyD88非依赖途径进行信号转导,不同的接头蛋白决定了不同TLR的信号转导途径,本文针对各含TIR的接头蛋白对TLR信号转导通路研究进展作一综述。
