病原体已经进化出聪明的策略来入侵宿主并劫持它们的免疫反应。一种这样的策略是通过毒素或毒力因子靶向宿主RhoGTP酶以劫持细胞骨架动力学和免疫过程。为了应对这种微生物的攻击,宿主已经进化出一种优雅的策略,通过检测RhoGTPases的异常活性来监测毒力因子和毒素的功能。这种感测细菌效应子靶向RhoGTdR的先天免疫策略似乎是效应子触发免疫(ETI)的真实实例。在这里,我们回顾了最近发现的机制,宿主可以通过NOD和NOD样受体(NLR)来感知这些毒素的活性。
Pathogens have evolved smart strategies to invade hosts and hijack their immune responses. One such strategy is the targeting of the host RhoGTPases by toxins or virulence factors to hijack the cytoskeleton dynamic and immune processes. In response to this microbial attack, the host has evolved an elegant strategy to monitor the function of virulence factors and toxins by sensing the abnormal activity of RhoGTPases. This innate immune strategy of sensing bacterial effector targeting RhoGTPase appears to be a bona fide example of effector-triggered immunity (ETI). Here, we review recently discovered mechanisms by which the host can sense the activity of these toxins through NOD and NOD-like receptors (NLRs).
