摘要:

新生隐球菌感染机体后,经固有免疫细胞表面的模式识别受体(pattern recognition receptors,PRRs)识别病原相关分子模式(pathogen-associated molecular patterns,PAMPs),引发下游的信号传导通路,激活核因子NF-κB,进而启动固有免疫和适应性免疫,诱导相关炎症因子的生成,活化Th1、Th2、Th17等适应性免疫细胞,同时募集巨噬细胞吞噬清除隐球菌。目前对隐球菌模式识别受体的种类及功能仍有待探索,对其下游信号传导通路的研究需深入,充分研究模式识别受体和下游信号传导,将对隐球菌病的免疫调节和临床治疗提供思路。

Abstract:

Pattern recognition receptors(PRRs) presented on the surface of host innate immune cells recognize the pathogen-associated molecular patterns(PAMPs) of Cryptococcus neoformans after the invasion,which will trigger downstream sinaling pathways and activate nuclear factor-kappa B(NF-κB) in immune cells,ultimately initiating innate and adaptive immunity,inducing the release of correlative inflammatory factors,activating adaptive immune cells such as Th1,Th2,Th17 cells,recruiting macrophage to eliminate Cryptococcus neoformans.Deep insights into PRRs and downstream pathways will contribute to obtain an overall understanding of immune adjustment and provide superior clinical therapys.

Key words: Cryptococcus neoformans, pattern recognition receptors(PRRs), signaling pathway, immunity
