Abstract

It was found that a high proportion of IgM-producing cells secrete homophile or heterophile rheumatoid factors (RF). Injection of lipopolysaccharide (LPS) into CBA mice resulted in a sharp increase in total IgM and in RF-producing cells and in some cases resulted in an increase in RF-producing cells as a proportion of total IgM. RF plaques are indirect IgM in the sense that they require development by IgG2 (anti-IgM) antibody for visualization in a standard haemolytic plaque assay. The RF response to LPS is both dose- and time-dependent.

摘要

研究发现,高比例产生IgM的细胞分泌亲同种抗体或亲异种抗体类风湿因子(RF)。向CBA小鼠注射脂多糖(LPS)导致总IgM和产生RF的细胞急剧增加,在某些情况下,产生RF的细胞占总IgM的比例增加。RF噬斑是间接IgM,因为在标准溶血噬斑试验中,它们需要IgG2(抗IgM)抗体的作用才能显现。对LPS的RF反应具有剂量和时间依赖性。
