自然杀伤(NK)细胞被赋予细胞结构感应受体,其提供针对自我破坏的抑制性保护(抑制性NK受体,iNKR,包括杀伤抑制性受体和其他分子)和快速触发潜力,导致通过Toll样受体(TLR)、细胞因子受体和活化NK细胞受体(包括天然细胞毒性受体(NCR,即,NKp46、NKp46和NKp44)。NCR和NKG2D识别受感染细胞上的配体,这些配体可能是内源性的,也可能直接结合来自入侵病原体的一些结构。在本文中,我们解决了已知的直接或间接的激活受体和病原体之间的相互作用和它们的表达在慢性HIV和HCV感染。
Natural Killer (NK) cells are endowed with cell-structure-sensing receptors providing inhibitory protection from self-destruction (inhibitory NK receptors, iNKRs, including killer inhibitory receptors and other molecules) and rapid triggering potential leading to functional cell activation by Toll-like receptors (TLRs), cytokine receptors, and activating NK cell receptors including natural cytotoxicity receptors (NCRs, i.e., NKp46, NKp46, and NKp44). NCR and NKG2D recognize ligands on infected cells which may be endogenous or may directly bind to some structures derived from invading pathogens. In this paper, we address the known direct or indirect interactions between activating receptors and pathogens and their expression during chronic HIV and HCV infections.
