核苷酸结合域富含亮氨酸重复序列的受体(NLR)是细胞溶质受体,启动对宿主无菌和感染性损伤的免疫反应。研究表明,Nlrp3对于控制白色念珠菌感染和产生抗真菌Th17应答至关重要。在这里,我们表明,NLR家族成员Nlrp10也发挥了独特的作用,在控制传播的C。体内白色念珠菌感染。Nlrp10基因缺陷小鼠对播散性念珠菌病的易感性增加,表现为存活率降低和真菌负荷增加。与Nlrp3相反,Nlrp10缺陷不影响用C.白色念珠菌然而,Nlrp10缺陷型小鼠显示出显著的缺陷,在特定的Th1和Th17反应。这些结果证明了Nlrp10在产生对真菌感染的适应性免疫应答中的新作用。
Nucleotide-binding domain leucine-rich repeat containing receptors (NLRs) are cytosolic receptors that initiate immune responses to sterile and infectious insults to the host. Studies have demonstrated that Nlrp3 is critical for the control of Candida albicans infections and in the generation of anti-fungal Th17 responses. Here we show that the NLR family member Nlrp10 also plays a unique role in the control of disseminated C. albicans infection in vivo. Nlrp10-deficient mice had increased susceptibility to disseminated candidiasis as indicated by decreased survival and increased fungal burdens. In contrast to Nlrp3, Nlrp10-deficiency did not affect innate proinflammatory cytokine production from macrophages and dendritic cells challenged with C. albicans. However, Nlrp10-deficient mice displayed a profound defect in Candida-specific Th1 and Th17 responses. These results demonstrate a novel role for Nlrp10 in the generation of adaptive immune responses to fungal infection.
