Abstract

A common idiotype was defined by a guinea pig anti-idiotypic antiserum made against D1.LP antibodies specific to the synthetic terpolymer poly(Glu60Ala30Tyr10), referred to as GAT. This idiotype was found in the anti-GAT antibodies of all individuals of all inbred strains of mice tested. Due to its common (C) occurrence in the anti-GAT antibodies of all mouse strains, it was termed the CGAT idiotype. The presence of CGAT idiotype in mice is independent of the expression of various Ig-1, H-2, or Vg genetic markers. In contrast, antibodies produced in response to the crossreactive poly(Glu60-Ala40), termed GA, bound to the GAT ligand but did not bear the CGAT idiotype. This suggests that GAT, although bearing GA determinants, preferentially stimulates clones of CGAT idiotype. Some of the CGAT idiotypic specificities were also identified in sera of WF inbred rats after immunization with GAT. However, no significant levels of CGAT idiotype were detected in LEW rats, F344 rats, guinea pigs, or rabbits, although measurable quantities of anti-GAT antibody were present.

摘要

一种常见独特型是由针对合成三元共聚物聚(Glu60Ala30Tyr10)(称为GAT)的D1.LP抗体产生的豚鼠抗独特型抗血清所定义。在所有测试的近交系小鼠个体的抗GAT抗体中都发现了这种独特型。由于其在所有小鼠品系的抗GAT抗体中普遍(C)存在,故将其称为CGAT独特型。小鼠中CGAT独特型的存在与各种Ig-1、H-2或Vg基因标记的表达无关。相反,针对交叉反应性聚(Glu60-Ala40)(称为GA)产生的抗体与GAT配体结合,但不具有CGAT独特型。这表明GAT虽然带有GA决定簇,但优先刺激CGAT独特型的克隆。在用GAT免疫后的WF近交系大鼠血清中也鉴定出了一些CGAT独特型特异性。然而,在LEW大鼠、F344大鼠、豚鼠或兔子中未检测到显著水平的CGAT独特型,尽管存在可测量量的抗GAT抗体。
