内体Toll样受体(TLR)TLR 3、TLR 7、TLR 8和TLR 9在感受吞噬细胞遇到的外源核酸中是重要的。由于TLR 8最初被认为在小鼠中是无功能的,因此对TLR 8的了解比遗传和功能相关的TLR 7少。最初与病毒来源的单链RNA的识别相关,现在有证据表明人TLR 8也能够感知吞噬体空泡内释放的细菌RNA,诱导核因子(NF)-κ B依赖性细胞因子和I型干扰素(IFN)(如IFN-β)的产生。TLR 8的功能超出了对外来病原体的识别,并且包括与其他内体TLRs的串扰,这一过程也可能在自身免疫的产生中起作用。
The endosomal Toll-like receptors (TLRs) TLR3, TLR7, TLR8 and TLR9 are important in sensing foreign nucleic acids encountered by phagocytes. Because TLR8 was initially thought to be non-functional in mice, less is known about TLR8 than the genetically and functionally related TLR7. Originally associated with the recognition of single-stranded RNA of viral origin, there is now evidence that human TLR8 is also able to sense bacterial RNA released within phagosomal vacuoles, inducing the production of both nuclear factor (NF)-κB-dependent cytokines and type I interferons (IFNs), such as IFN-β. The functions of TLR8 extend beyond the recognition of foreign pathogens and include cross-talk with other endosomal TLRs, a process that may also have a role in the generation of autoimmunity.
