Abstract

Lymphocytes from the peripheral blood of newborn rabbits heterozygous for IgG allotypes As4 and As5, or As5 and As6, obtained at an age when only the maternal allotypic determinants are detectable in the serum, may be stimulated in vitro to transform into "blast" cells with antiallotype sera directed against the determinants contolled both by the maternal and by the paternal chromosomes. This result rules out the possibility that allotypic specificity is conferred upon lymphocytes by environmental IgG and suggests that the lymphocytes of newborn rabbits have the potential to synthesize IgG determinants either in the form of intact IgG molecules or constituent polypeptide chains.

摘要

从新生兔外周血中获取的淋巴细胞,这些新生兔对于IgG同种异型As4和As5或As5和As6是杂合子,在血清中仅能检测到母体同种异型决定簇的年龄时获取,用针对由母体和父体染色体控制的决定簇的抗同种异型血清在体外刺激,可转化为“母细胞”。这一结果排除了环境IgG赋予淋巴细胞同种异型特异性的可能性,并表明新生兔的淋巴细胞有潜力以完整IgG分子或组成多肽链的形式合成IgG决定簇。
