To expand the spectrum of recognition of effector lymphocytes and to redirect them towards predefined targets, we have altered the specificity of human tumor-infiltrating lymphocytes (TIL) through stable modification with chimeric receptor genes consisting of single-chain antibody variable regions linked to the gamma subunit common to the immunoglobulin (Ig)G and IgE Fc receptors. Using either hapten or ovarian carcinoma-specific monoclonal antibodies, we constructed chimeric receptor genes and retrovirally introduced them into CD8+ TIL. Redirected TIL specifically lysed trinitrophenyl-labeled Daudi or a human ovarian carcinoma cell line (IGROV-1), and secreted granulocyte/macrophage colony-stimulating factor upon stimulation with the appropriate antigen. This strategy may allow new approaches towards the adoptive immunotherapy of cancer in humans.
为了扩大效应淋巴细胞的识别谱并将它们重定向至预定义的靶标,我们通过用嵌合受体基因进行稳定修饰改变了人肿瘤浸润淋巴细胞(TIL)的特异性,该嵌合受体基因由与免疫球蛋白(Ig)G和IgE Fc受体共有的γ亚基相连的单链抗体可变区组成。利用半抗原或卵巢癌特异性单克隆抗体,我们构建了嵌合受体基因,并通过逆转录病毒将其导入CD8 + TIL。重定向的TIL特异性裂解三硝基苯基标记的Daudi或人卵巢癌细胞系(IGROV-1),并在受到适当抗原刺激时分泌粒细胞/巨噬细胞集落刺激因子。该策略可能为人类癌症的过继性免疫治疗带来新方法。
