为了应对昆虫和哺乳动物的细菌和真菌感染,不同的天然免疫模式识别受体(PRRs)家族启动了高度复杂的细胞内信号级联反应。这些级联反应诱导了各种免疫功能,抑制了微生物在宿主中的传播。昆虫和哺乳动物的先天免疫受体包括识别保守微生物分子模式的分子。先天免疫识别导致适配器分子的招募,形成包括激酶、转录因子和其他调节分子在内的多蛋白质复合体。先天免疫信号级联反应诱导抗菌肽和其他关键因子的表达,从而启动和调节针对微生物攻击的免疫反应。本文就细菌和真菌对昆虫和哺乳动物同源先天信号通路的PRRs的研究现状进行综述,以期为今后的研究提供一个框架。
In response to bacterial and fungal infections in insects and mammals, distinct families of innate immune pattern recognition receptors (PRRs) initiate highly complex intracellular signaling cascades. Those cascades induce a variety of immune functions that restrain the spread of microbes in the host. Insect and mammalian innate immune receptors include molecules that recognize conserved microbial molecular patterns. Innate immune recognition leads to the recruitment of adaptor molecules forming multi-protein complexes that include kinases, transcription factors, and other regulatory molecules. Innate immune signaling cascades induce the expression of genes encoding antimicrobial peptides and other key factors that mount and regulate the immune response against microbial challenge. In this review, we summarize our current understanding of the bacterial and fungal PRRs for homologous innate signaling pathways of insects and mammals in an effort to provide a framework for future studies.
