We investigated the feasibility of generating cytotoxic T cell clones against autologous human melanoma cells using a melanoma cell line (VIP) and a spontaneously transformed autologous fibroblast line (VIP-F:T). Cytotoxic lymphocytes (CL) generated against the VIP melanoma cells in one-way mixed lymphocyte-tumor cell interactions were expanded in interleukin 2 for 2 wk. The expanded CL were cloned in limiting dilution. Two phenotypically homogeneous clones (3:1 and E.5) were obtained bearing OKT3 phenotype. Both clones expressed cytotoxicity selectively only against the sensitizing autologous target VIP. cytotoxicity assays performed with clone E.5 against the VIP target cells in the presence of autologous unfractionated lymphocytes or serum showed no modulation of autoreactivity of clone E.5. These results indicate that analysis of cellular immune response against autologous tumor cells might be feasible using autoreactive clones generated by the currently available in vitro cloning technology.
我们研究了使用黑色素瘤细胞系(VIP)和自发转化的自体成纤维细胞系(VIP-F:T)产生针对自体人黑色素瘤细胞的细胞毒性T细胞克隆的可行性。在单向混合淋巴细胞-肿瘤细胞相互作用中针对VIP黑色素瘤细胞产生的细胞毒性淋巴细胞(CL)在白细胞介素2中扩增2周。将扩增的CL进行有限稀释克隆。获得了两个表型均一的克隆(3:1和E.5),它们具有OKT3表型。两个克隆均仅对致敏的自体靶细胞VIP选择性地表达细胞毒性。在存在自体未分级淋巴细胞或血清的情况下,用克隆E.5对VIP靶细胞进行的细胞毒性测定显示克隆E.5的自身反应性没有调节。这些结果表明,使用当前可用的体外克隆技术产生的自身反应性克隆来分析针对自体肿瘤细胞的细胞免疫反应可能是可行的。
