Toll样受体(Toll-like Receptor,TLRs)是模式识别受体(PRRs)的一个重要家族,通过信号转导途径参与机体对病原体感染的免疫应答。然而,TLR信号通路也可能通过复杂的调节机制严格调节组织的维持和动态平衡。MicroRNAs(MiRNAs)已经成为关键的调节者,并成为参与调节TLR信号通路的网络的重要组成部分。在这篇综述中,我们强调了我们对TLR信号通路对miRNA表达谱的调节以及miRNAs对TLR信号通路的调节的理解。我们重点研究了miRNAs通过在多个水平上靶向多个分子,包括TLR本身、与其相关的信号蛋白和调节分子以及由其诱导的转录因子和功能细胞因子,在调节TLR信号通路中的作用。
Toll-like receptors (TLRs), a critical family of pattern recognition receptors (PRRs), are responsible for the innate immune responses via signalling pathways to provide effective host defence against pathogen infections. However, TLR-signalling pathways are also likely to stringently regulate tissue maintenance and homeostasis by elaborate modulatory mechanisms. MicroRNAs (miRNAs) have emerged as key regulators and as an essential part of the networks involved in regulating TLR-signalling pathways. In this review, we highlight our understanding of the regulation of miRNA expression profiles by TLR-signalling pathways and the regulation of TLR-signalling pathways by miRNAs. We focus on the roles of miRNAs in regulating TLR-signalling pathways by targeting multiple molecules, including TLRs themselves, their associated signalling proteins and regulatory molecules, and transcription factors and functional cytokines induced by them, at multiple levels.
