The functional properties of B lymphocytes in synovial fluid (SF) from patients with rheumatoid arthritis (RA) were analysed by means of a reverse haemolytic plaque forming cell (PFC) assay. SF mononuclear cells spontaneously secreted IgG, but little IgM or IgA. The SF cells failed to respond to the polyclonal B cell activators pokeweed mitogen (PWM) and Epstein-Barr virus. However, SF B cells cocultured with autologous T lymphocytes from the blood and stimulated with PWM secreted IgG but little IgM or IgA. The PFC responses of blood B cells cocultured with autologous SF T cells in the presence of PWM were low; irradiation of the T cells increased the blood B lymphocyte responses, but the differences were not statistically significant. It is concluded that suppressor SF T cells may be partly responsible for the poor response of SF B cells to PWM.
通过反向溶血空斑形成细胞(PFC)试验分析了类风湿性关节炎(RA)患者滑液(SF)中B淋巴细胞的功能特性。滑液单核细胞自发分泌IgG,但很少分泌IgM或IgA。滑液细胞对多克隆B细胞激活剂商陆有丝分裂原(PWM)和爱泼斯坦-巴尔病毒无反应。然而,与来自血液的自体T淋巴细胞共培养并用PWM刺激的滑液B细胞分泌IgG,但很少分泌IgM或IgA。在PWM存在下与自体滑液T细胞共培养的血液B细胞的PFC反应较低;T细胞照射增加了血液B淋巴细胞反应,但差异无统计学意义。得出的结论是,抑制性滑液T细胞可能部分导致了滑液B细胞对PWM反应不佳。
