摘要:
Toll样受体(TLRs)是一种重要的模式识别受体(PRR),主要通过2条信号通路向下游传递信号以发挥免疫学效应。经过下游分子诱导的TLR通过和其他PRR(包括其他TLRs)、免疫分子和蛋白酶类的交叉作用,即Cross-talk,与炎症性疾病的发生发展过程密切相关。TLR信号通路包括MyD88依赖信号通路和MyD88非依赖性信号通路(TRIF通路),其下游的信号分子肿瘤坏死因子受体相关因子3(TRAF3)和肿瘤坏死因子受体相关因子6(TRAF6),在引导信号传导方向的过程中起重要作用。TLRs信号通路能完全激活炎症,而TLRs的Cross-talk参与各种炎症性疾病的预后和转归。TLRs的Cross-talk在系统性红斑狼疮、急性肺损伤和脓毒症等炎症性疾病的发生过程中通过增加细胞因子的分泌、激活蛋白酶使免疫细胞过度活化和增强免疫细胞的趋化作用加速相关疾病进程,甚至在炎症末期因机体免疫分子及免疫细胞消耗过度而引发免疫抑制,这阻碍了机体免疫稳态的维持。现对炎症性疾病进程中组织和细胞中TLRs信号通路分子的表达变化及其Cross-talk作用的分子机制进行综述,深入了解TLRs的Cross-talk在炎症发生发展中的作用机制,为治疗炎症性疾病提供新的策略和靶标。
