Members of the nucleotide-binding and oligomerization domain (NOD)-like receptor (NLR) family are quickly emerging as critical regulators of innate and adaptive immune responses during microbial infection and autoimmunity. The NLR family member NLRC5 was recently proposed to function as a positive and negative regulator of antiviral immune responses. NLRC5 has also been implicated in regulation of inflammasome signaling and MHC class I transcription. Some of these functions have recently been assessed in NLRC5-deficient mice and immune cells. Here, we summarize and review the newly gained knowledge on the structure, expression profile and putative functions of NLRC5 in regulating immune responses and host defense.
核苷酸结合寡聚化结构域(NOD)样受体(NLR)家族成员在微生物感染和自身免疫过程中迅速成为先天和适应性免疫反应的关键调节因子。最近提出 NLR 家族成员 NLRC5 作为抗病毒免疫反应的正调节因子和负调节因子。NLRC5 还参与调节炎症小体信号和 MHC Ⅰ类转录。这些功能中的一些最近在 NLRC5 缺陷小鼠和免疫细胞中进行了评估。在这里,我们总结和回顾了 NLRC5 在调节免疫反应和宿主防御方面的结构、表达谱和潜在功能的新认识。
