为了阐明B细胞生长因子(BCGF)在系统性红斑狼疮(SLE)发病机制中的作用,采用一种新的BCGF活性生物测定方法,研究外周血单个核细胞(PBMC)和T细胞产生BCGF。为此,我们建立了Epstein‐Barr (EB)病毒转化的B细胞系KS‐3。F10仅对两种B细胞特异性BCGF有增殖反应。wt BCGF (LMW‐BCGF)和high‐mol。wt BCGF (HMW - BCGF)。与对照组相比,活动性SLE患者的PBMC在植物血凝素(PHA)刺激下产生更少的BCGF。当SLE变得不活跃时,由PHA刺激的活动性SLE的PBMC产生的BCGF减少恢复到控制值。然而,与对照组相比,活动性SLE患者的PHA刺激T细胞产生更多的BCGF,而非活动性SLE患者的BCGF产生正常。在活动期SLE患者中未观察到T细胞自发产生BCGF。这些研究结果表明,SLE PBMC产生BCGF的减少是由于体外B细胞消耗过多的BCGF, SLE T细胞在体外适当的免疫刺激下产生大量BCGF以促进多克隆B细胞活化。
In order to clarify the role of B cell growth factor (BCGF) in the pathogenesis of systemic lupus erythematosus(SLE), BCGF production by peripheral blood mononuclear cells(PBMC) and T cells was studied using a new bioassay for BCGF activity. For this purpose, we established an Epstein‐Barr (EB) virus‐transformed B cell line KS‐3.F10 that proliferates only in response to two B cell‐specific BCGF, low‐mol. wt BCGF (LMW‐BCGF) and high‐mol. wt BCGF (HMW‐BCGF). PBMC from active SLE patients produced less BCGF when stimulated with phytohaemagglutinin (PHA) compared with controls. The decreased BCGF production by PHA‐stimulated PBMC from active SLE reverted to control values when SLE became inactive. However, PHA‐stimulated T cells from active SLE patients produced more BCGF compared with controls, whereas those from inactive SLE showed normal BCGF production. Spontaneous BCGF production by T cells was not observed in active SLE patients. These findings suggest that decreased BCGF production by SLE PBMC is due to excessive BCGF consumption by B cells in vitro and that SLE T cells produce large amounts of BCGF with appropriate immune stimuli in vitro to promote polyclonal B cell activation.
