T细胞抗原受体（Tcellreceptor，TCR）γδT细胞是T淋巴细胞的一个亚类。TCRγδT细胞具有抗感染、抗肿瘤及抗过敏等作用。它们可识别杀伤某些病毒和胞内寄生菌感染的靶细胞、表达热休克蛋白和异常表达CD１分子的靶细胞和某些肿瘤细胞，还可分泌多种细胞因子，参与免疫调节和介
T cell receptor (TCR) γδ T cells are a subset of T lymphocytes. TCRγδT cells have anti-infective, anti-tumor and anti-allergic effects. They recognize target cells that kill certain viruses and intracellular parasitic infections, express heat shock proteins and target cells that are abnormally expressed on CD1 and certain tumor cells, and also secrete many cytokines that are involved in immune regulation and mediation
