细胞毒Ｔ淋巴细胞（ＣＴＬ）对肿瘤细胞的特异性识别与ＣＴＬ及肿瘤细胞表面的分子结构密切相关。对ＣＴＬ表面ＴＣＲ┐ＣＤ３，ＣＤ４／ＣＤ８分别与肿瘤细胞表面的抗原性多肽、ＭＨＣ分子的特异性结合及二者表面粘附分子所介导的非特异性粘着两个相关过程，综述ＣＴＬ对肿瘤细胞的特异性识别机制 The specific recognition of tumor cells by cytotoxic T lymphocytes (CTL) is closely related to the molecular structure of CTL and the surface of tumor cells. The related processes of TCR┐CD3 and CD4/CD8 on the surface of CTL and the specific binding of antigenic peptides and MHC molecules on the surface of tumor cells and the non-specific adhesion mediated by the two surface adhesion molecules were reviewed. Specific recognition mechanism
