弓形虫是一种普遍分布的病原体,感染了全世界超过10亿人。宿主对这种原生动物寄生虫的抗性取决于IL-12和IFN-γ的有效产生。尽管Toll样受体11(TLR 11)在控制小鼠对该病原体的Th 1免疫中起主要作用,但这种先天性免疫受体在人类中没有功能,并且TLR 11非依赖性的T.弓形虫仍然难以捉摸。在这里,我们表明,粘膜先天性和适应性免疫反应T。弓形虫依赖于正常肠道微生物群对树突状细胞的间接刺激。我们确定了一种新的功能,寄生虫感染过程中,它们提供了树突状细胞的免疫刺激作用。我们的研究结果表明,肠肽的间接免疫刺激提供了对T。在TLR 11不存在的情况下,
Toxoplasma gondii is a universally-distributed pathogen that infects over 1 billion people worldwide. Host resistance to this protozoan parasite depends on the potent production of IL-12 and IFN-γ. Although Toll-like receptor 11 (TLR11) plays a major role in controlling Th1 immunity to this pathogen in mice, this innate immune receptor is not functional in humans, and the mechanisms of TLR11-independent sensing of T. gondii remain elusive. Here, we show that both mucosal innate and adaptive immune responses to T. gondii rely on the indirect stimulation of dendritic cells by normal gut microflora. We identify a novel function for commensal bacteria in which they provide an immunostimulatory effect on dendritic cells during parasitic infection. Our results reveal that indirect immunostimulation by gut commensals provides protection against T. gondii in the absence of TLR11.
