Hapten-binding receptor material was isolated from sensitized rabbit lymphocytes by a method described previously for murine receptor material. The material was separated into a fraction expressing immunoglobulin determinants (anti-Ig+ fraction) and a fraction lacking known class and type-specific determinants of Ig constant domains (anti-Ig- fraction). We present evidence in support of the notion that--in analogy to the mouse system--the anti-Ig+ fraction is B-cell-derived, whereas the anti-Ig- fraction originates from T lymphocytes. Receptors of the anti-Ig- phenotype are found to express a locus allotypic determinants and, thus, appear to carry variable portions of immunoglobulin heavy chains.
采用先前描述的用于分离鼠源受体物质的方法,从致敏兔淋巴细胞中分离出半抗原结合受体物质。该物质被分离为表达免疫球蛋白决定簇的部分(抗Ig+部分)和缺乏已知Ig恒定区类别和型特异性决定簇的部分(抗Ig-部分)。我们提供的证据支持这样一种观点,即类似于小鼠系统,抗Ig+部分来源于B细胞,而抗Ig-部分起源于T淋巴细胞。发现抗Ig-表型的受体表达一个基因座同种异型决定簇,因此似乎携带免疫球蛋白重链的可变部分。
