Toll样受体与细菌感染

摘要

Toll样受体( TLR)是一类Ⅰ型跨膜糖蛋白模式识别受体，其可通过识别病原体，激活天然免疫，诱导产生多种细胞因子，在抗感染免疫中发挥重要作用，研究显示细菌感染与TLR密切相关。该文就TLR与细菌感染的关系进行综述。%Toll-like receptor( TLR) ,which belongs to pattern recognition receptor,is type I transmem-brane glycoprotein. TLR activates natural immune and induces several cytokines. Foreign studies have showed that bacterial infection is closely related with TLR. In this paper,the relationship between TLR and bacterial in-fection is reviewd.
