二甲基苯并蒽诱导的 P1 肉瘤细胞在同基因 DA 大鼠中诱导 P1 特异性抗体。针对肿瘤特异性抗体诱导特异性 DA 抗(DA 抗 P1)的抗独特型抗体,并用于在体外重新刺激 P1 引发的 DA T 细胞。使用抗独特型抗体和T细胞生长因子,通过有限稀释建立P1特异性细胞毒性DA T细胞克隆并保存在体外。除了针对自然杀伤 (NK) 靶标 YAC-1 或 K562 的 P1 特异性裂解活性外,其中两个克隆是在培养期间获得的。冷靶抑制实验表明,相同的细胞毒性 T 细胞杀死 P1 和 NK 靶标。特异性 DA 抗(DA 抗 P1)的抗独特型抗体抑制针对 P1 的细胞毒性,但不抑制针对 YAC-1 或 K562 的细胞毒性。我们得出结论,两个独立的受体位于这些双反应性 T 细胞克隆上,一个是独特型和抗原特异性的,另一个显示 NK 细胞的结合特征。
Dimethylbenzanthracene-induced P1 sarcoma cells induce P1-specific antibodies in syngeneic DA rats. Antiidiotypic antibodies of specificity DA anti-(DA anti-P1) were induced against the tumor- specific antibodies and used to restimulate P1-primed DA T cells in vitro. Using antiidiotypic antibodies and T cell growth factor, P1- specific cytotoxic DA T cell clones were established by limiting dilution and kept in vitro. Two of these clones acquired during culture periods in addition to the P1 specificity lytic activity towards natural killer (NK) targets YAC-1 or K562. Cold target inhibition experiments showed that the very same cytotoxic T cells kill P1 and NK targets. Antiidiotypic antibodies of specificity DA anti-(DA anti-P1) inhibited cytotoxicity against P1 but not against YAC-1 or K562. We conclude that two independent receptors are located on these double- reactive T cell clones, one that is idiotypic and antigen-specific, and another displaying the binding profile of NK cells.
