This study characterizes four private idiotypes (Id) associated with monoclonal antibodies (mAb) to simian virus 40 (SV40) tumor antigen (T-Ag), and to a cellular protein, p53. Anti-Id recognized Id determinants associated with the antibody-combining site. BALB/c mice receiving a pool of anti-Id directed against mAb recognizing distinct amino and carboxyl terminal epitopes of T-Ag before receiving a tumorigenic dose of SV40-transformed cells showed suppression of tumor formation. Serum obtained from these mice before tumor challenge contained anti-anti-Id that failed to bind T-Ag. These data support the potential role of regulatory idiotopes in tumor immunity.
本研究对四种与抗猿猴病毒40(SV40)肿瘤抗原(T-Ag)及一种细胞蛋白p53的单克隆抗体(mAb)相关的独特型(Id)进行了表征。抗独特型识别与抗体结合位点相关的独特型决定簇。在接受致瘤剂量的SV40转化细胞之前,接受针对识别T-Ag不同氨基和羧基末端表位的mAb的抗独特型混合物的BALB/c小鼠显示出肿瘤形成受到抑制。在肿瘤攻击前从这些小鼠获得的血清中含有无法结合T-Ag的抗抗独特型。这些数据支持调节性独特型在肿瘤免疫中的潜在作用。
