TRAF6

TLR信号通路：先天免疫的关键角色 𐟛᯸ 先天性免疫系统在抵御病原体入侵时扮演着至关重要的角色，而Toll样受体（TLRs）正是这一系统中的关键成员。它们能够识别各种病原体相关分子模式，从而触发免疫应答。TLRs在炎症反应、免疫细胞调控以及细胞存活和增殖等方面都发挥着重要作用。 TLR的定位 𐟓 TLR1、TLR2、TLR4、TLR5、TLR6和TLR11主要定位在质膜上，而TLR3、TLR7、TLR8和TLR9则存在于内小体中。内体是一种膜包裹的囊泡结构，分为初级内体和次级内体，通常位于细胞质的外侧或内侧，具有酸性特征且不含溶酶体酶。 TLR与核酸识别 𐟧슔LR3主要识别双链长链RNA（dsRNA），而TLR7和TLR8则能够识别RNA降解产物。TLR9则能够识别含有CpG的DNA。 TLR信号通路的主要过程 𐟚€ TLR和IL-1受体家族成员共享一个约200个氨基酸的保守区域，称为Toll/Interleukin-1受体（TIR）结构域。激活后，TLR与多种细胞浆接头蛋白相互作用，包括髓样分化因子88（MyD88）、MyD88样接头蛋白/TIR相关接头蛋白（MAL/TIRAP）、Toll受体相关的干扰素激活剂（TRIF）和Toll受体相关的分子（TRAM）。经过配体的刺激，MyD88将IL-1受体相关激酶-4（IRAK-4）吸引到TLRs，随后IRAK-1被磷酸化激活并与TRAF6发生作用，从而激活IKK复合体并导致MAP激酶（JNK、p38 MAPK）和NF-的激活。这些复杂的信号转导过程最终导致炎症反应的发生，从而帮助机体抵御病原体的入侵。
