自然杀伤性T(natural killer T cell,NKT)细胞是非特异性T淋巴细胞的一类亚群,可同时表达自然杀伤细胞及T细胞的相关受体,与自然杀伤(natural killer,NK)细胞共享部分表型及功能[1]。NKT细胞可被分为两类亚群:Ⅰ型(iNKT)及Ⅱ型NKT细胞(iiNKT)。其中iNKT也被称为经典NKT,其可以 Natural killer T cells (NKTs) are a subset of nonspecific T lymphocytes that express both natural killer (NK) cells and natural killer (NK) cells simultaneously Partial phenotype and function [1]. NKT cells can be divided into two subgroups: type I (iNKT) and type II NKT cells (iiNKT). Among them, iNKT is also called classic NKT, which can be
