Abstract

Guinea-pigs have been sensitized with DNCB, DNP-guinea-pig serum and DNP-guinea-pig erythrocytes. Four, six and ten days after sensitization numbers of rosette-forming cells with DNP-erythrocytes were estimated in the draining lymph nodes. It was found that the numbers of DNP-erythrocyte RFC did not correlate with humoral immunity as estimated by haemagglutination assay, but did so with cell-mediated immunity estimated as delayed-type hypersensitivity. On the other hand histological examination of the draining lymph nodes gave no clear confirmation of such a relationship. Experiments on the antigenic specificity of RFC showed that after DNCB sensitization a clear increase in oxazolone-erythrocyte RFC and SRBC RFC can be found. These latter data suggest formation of RFC to be at least partly a non-specific phenomenon.

摘要

豚鼠已用二硝基氯苯(DNCB)、二硝基苯基 - 豚鼠血清和二硝基苯基 - 豚鼠红细胞致敏。致敏后4天、6天和10天,在引流淋巴结中估计与二硝基苯基红细胞形成玫瑰花结细胞的数量。结果发现,二硝基苯基红细胞玫瑰花结形成细胞(RFC)的数量与通过血凝试验估计的体液免疫不相关,但与作为迟发型超敏反应估计的细胞介导免疫相关。另一方面,对引流淋巴结的组织学检查并未明确证实这种关系。关于RFC抗原特异性的实验表明,在DNCB致敏后,可以发现恶唑酮红细胞RFC和绵羊红细胞RFC明显增加。这些数据表明RFC的形成至少部分是一种非特异性现象。
