Abstract

The fine specificity of anti-idiotypic, effector-phase suppressor T cells (Ts2) induced by the intravenous injection of syngeneic spleen cells covalently coupled with the 4-hydroxy-3-nitrophenyl acetyl (NP) hapten was studied in an in vitro plaque-forming cell system. By comparing the ability of these suppressor cells to bind monoclonal anti-NP antibodies that express different levels of serologically detected NPb idiotypic determinants, it was shown that anti-idiotypic suppressor T cells do not recognize the predominant NPb idiotypic determinants that are defined by serologic analysis. The implications for the possible expression and/or recognition of different sets of idiotypic determinants on T and B cells are discussed.

摘要

在体外空斑形成细胞系统中,研究了静脉注射与4-羟基-3-硝基苯基乙酰(NP)半抗原共价偶联的同基因脾细胞所诱导的抗独特型效应阶段抑制性T细胞(Ts2)的精细特异性。通过比较这些抑制性细胞结合表达不同血清学检测到的NPb独特型决定簇水平的单克隆抗NP抗体的能力,结果表明抗独特型抑制性T细胞不能识别血清学分析所定义的主要NPb独特型决定簇。文中讨论了T细胞和B细胞上不同组独特型决定簇可能的表达和/或识别的意义。
