自然杀伤T(NKT)细胞通常识别在主要组织相容性复合体(MHC)I类样分子CD1d背景下呈递的脂质抗原。受CD1d限制的NKT细胞由两个主要亚群组成:I型表达不变的T细胞受体(TCR),II型则利用多种TCR基因片段。已表明一个主要的II型NKT亚群可识别一种自身糖脂——硫苷脂。这两个亚群在自身免疫性疾病、肿瘤监测和感染性疾病中都发挥着重要作用。I型NKT细胞通过增强肿瘤监测来防止肿瘤生长,而II型NKT细胞可能抑制抗肿瘤免疫反应。在一个小鼠自身免疫性肝炎模型中,I型NKT细胞促进发病机制,而硫苷脂反应性II型NKT细胞的激活可防止疾病发生。硫苷脂介导的II型NKT细胞激活导致树突状细胞发生改变,并诱导I型NKT细胞产生无反应性。阐明NKT细胞亚群之间这种新的交叉调节途径将为干预自身免疫性疾病以及设计有效的抗肿瘤免疫策略提供工具。
Natural Killer T (NKT) cells generally recognize lipid-antigens presented in the context of the MHC class I-like molecule CD1d. CD1d-restricted NKT cells consist of two broad subsets: Type I, which express an invariant T cell receptor (TCR) and type II, which utilize diverse TCR gene segments. A major type II NKT subset has been shown to recognize a self-glycolipid, sulfatide. Both subsets play important roles in autoimmune diseases, tumor surveillance, and infectious diseases. While type I NKT cells protect from tumor growth by enhancing tumor surveillance, type II NKT cells may suppress anti-tumor immune responses. In a murine autoimmune hepatitis model, type I NKT cells contribute to pathogenesis, whereas activation of sulfatide-reactive type II NKT cells protects from disease. Sulfatide-mediated activation of type II NKT cells results in modification of dendritic cells and induction of anergy in type I NKT cells. Elucidation of this novel pathway of cross-regulation among NKT cell subsets will provide tools for intervention in autoimmune diseases and for designing strategies for effective anti-tumor immunity.
