自然杀伤(NK)细胞代表了对病毒感染和癌症的关键防御。NK细胞需要整合激活性和抑制性NK细胞受体以检测靶细胞,这些NK细胞输入的平衡决定了整体NK细胞应答。反应的敏感性主要由自身主要组织相容性复合物I类(MHC-I)分子和特异性抑制性NK细胞受体之间的相互作用来定义,即所谓的NK细胞教育。因此,NK细胞教育是在不同疾病中产生调谐效应NK细胞应答的关键过程。在这篇综述中,我们讨论了NK细胞教育和生理因素之间的关系(类型的自我-MHC-I,自我-MHC-I等位基因变异体,变异的自我-MHC-I结合肽,细胞因子的影响和抑制性KIR表达)潜在的NK细胞教育概况(效应器功能或代谢)。此外,我们还描述了受不同病理学(如HIV-1、CMV和肿瘤等)影响的NK细胞功能的广谱性。
Natural killer (NK) cells represent a critical defense against viral infections and cancers. NK cells require integration of activating and inhibitory NK cell receptors to detect target cells and the balance of these NK cell inputs defines the global NK cell response. The sensitivity of the response is largely defined by interactions between self-major histocompatibility complex class I (MHC-I) molecules and specific inhibitory NK cell receptors, so-called NK cell education. Thus, NK cell education is a crucial process to generate tuned effector NK cell responses in different diseases. In this review, we discuss the relationship between NK cell education and physiologic factors (type of self-MHC-I, self-MHC-I allelic variants, variant of the self-MHC-I-binding peptides, cytokine effects and inhibitory KIR expression) underlying NK cell education profiles (effector function or metabolism). Additionally, we describe the broad-spectrum of effector educated NK cell functions on different pathologies (such as HIV-1, CMV and tumors, among others).
