The primary antibody response of C57BL/6 mice to the 4-hydroxy-3-nitrophenylacetyl (NP) hapten is restricted to antibody molecules expressing the NPb idiotype. This idiotype is a genetic marker for V genes in the heavy chain linkage group. In the secondary response, the frequency of NPb idiotype-positive molecules within the antibody population drops to very low values. Accordingly, isolated NP binding receptors from NP-sensitized B lymphocytes are largely devoid of this idiotype. In contrast, the NPb idiotype is expressed on the majority of the receptor fractions which we consider T-cell derived. This finding suggests that the antigen receptors of T lymphocytes may be restricted to the expression of major (germ-line encoded?) heavy chain idiotypes.
C57BL/6小鼠对4-羟基-3-硝基苯乙酰(NP)半抗原的初次抗体反应仅限于表达NPb独特型的抗体分子。这种独特型是重链连锁群中V基因的遗传标记。在二次反应中,抗体群体中NPb独特型阳性分子的频率降至非常低的值。因此,从NP致敏的B淋巴细胞中分离出的NP结合受体在很大程度上缺乏这种独特型。相反,NPb独特型在我们认为是T细胞来源的大多数受体组分上表达。这一发现表明,T淋巴细胞的抗原受体可能仅限于主要(种系编码的?)重链独特型的表达。
