The suppressor pathway that regulates the T cell response to p-azobenzenearsonate (ABA)-coupled cells has been studied. It has been found that the ability of anti-idiotypic second-order T suppressor cells (Ts2) to inhibit T cell-dependent delayed-type hypersensitivity (DTH) responses depended upon the presence of cross-reactive-idiotype (CRI)-bearing T cells present in ABA-primed mice. This suppressor T cell subset, termed Ts2, so exists with CRI-negative T cells that mediate DTH in vivo. It appears that antigen-activated CRI+ Ts3 require signals from the anti-CRI Ts2 subset to suppress DTH reactions in an idiotype-nonspecific manner. The relevance of these observations to a comprehensive scheme of T and B cell regulation is discussed.
已对调节T细胞对对氨基苯砷酸(ABA)偶联细胞反应的抑制途径进行了研究。已发现抗独特型二级T抑制细胞(Ts2)抑制T细胞依赖性迟发型超敏反应(DTH)的能力取决于ABA致敏小鼠中存在的携带交叉反应性独特型(CRI)的T细胞。这个被称为Ts2的抑制性T细胞亚群与体内介导DTH的CRI阴性T细胞共存。似乎抗原激活的CRI+ Ts3需要来自抗CRI Ts2亚群的信号,以独特型非特异性方式抑制DTH反应。讨论了这些观察结果与T和B细胞调节综合方案的相关性。
