Abstract

Sera from CBA and C57BL mice immunized against dextran B 512 eight or more days earlier contain mainly IgG antibodies that specifically suppress the development of plaque-forming cells against dextran in vitro. Suppression was not caused by antibodies against the alpha 1-6 epitope of dextran to any major extent. Sera from CBA mice (IgCH allotype j) suppressed plaque-forming cells from CBA mice, whereas sera from C57BL mice (allotype b) inhibited plaques from C57BL and CBA/Ig-1b mice. Sera from dextran-tolerant mice or from mice that are genetic unresponders to dextran did not suppress plaque-forming cells. Both thymus-independent and thymus-dependent forms of dextran induced the appearance of these autoantiidiotypic antibodies that can distinguish between anti-alpha 1-6 antibodies produced in mouse strains having different IgCH-locus-determined allotypes.

摘要

在八天或更早之前用葡聚糖B 512免疫的CBA和C57BL小鼠的血清,主要含有IgG抗体,这些抗体在体外能特异性抑制针对葡聚糖的噬斑形成细胞的发育。抑制作用在很大程度上并非由针对葡聚糖α1-6表位的抗体引起。CBA小鼠(IgCH同种异型j)的血清抑制CBA小鼠的噬斑形成细胞,而C57BL小鼠(同种异型b)的血清则抑制C57BL和CBA/Ig-1b小鼠的噬斑。来自葡聚糖耐受小鼠或对葡聚糖无遗传反应的小鼠的血清不抑制噬斑形成细胞。胸腺非依赖性和胸腺依赖性形式的葡聚糖均诱导这些自身抗独特型抗体的出现,这些抗体能够区分在具有不同IgCH基因座决定的同种异型的小鼠品系中产生的抗α1-6抗体。
