摘要:
目的研究系统性红斑狼疮(SLE)患者血浆对健康人骨髓来源的间充质干细胞(MSCs)免疫抑制作用的影响。方法采用 SLE患者富集血浆替代胎牛血清,共培养MSCs与SLE患者的B淋巴细胞,检测MSCs对B淋巴细胞增殖能力与成熟的影响。 设置胎牛血清作为对照组。数据采用SPSS12.0软件进行学生t检验统计学分析,P<0.05认为差异有统计学意义。结果正常 MSCs能抑制脂多糖刺激的SLE患者来源B细胞增殖,降低B细胞表面表达的CD27与CD38。SLE患者富集血浆能抵制MSC 对B淋巴细胞增殖与成熟的抑制作用。结论正常MSCs能抑制SLE患者B淋巴细胞增殖与成熟,改变B淋巴细胞亚群所占比 例。SLE患者血清能抑制MSCs对B淋巴细胞的免疫抑制作用,或将负向影响间充质干细胞对SLE的疗效。联合应用双膜过滤 血浆置换术,有望提高间充质干细胞移植对SLE的疗效。
Abstract:
Objective To investigate whether plasma from patients with systemic lupus erythematosus (SLE) inhibits the suppressive effects of mesenchymal stem cells (MSCs) on lupus B lymphocytes. Methods MSCs isolated and expanded from the bone marrow of healthy donors were co-cultured with B cells purified from the peripheral blood of SLE patients in the presence of fetal bovine serum or pooled plasma from SLE patients, and the proliferation and maturation of the B lymphocytes were analyzed. Results Co-culture with normal MSCs obviously inhibited the proliferation of lupus B cells and suppressed the maturation of B lymphocytes, which showed lowered expressions of CD27 and CD38. The pooled plasma from SLE patients significantly inhibited the suppressive effects of normal MSCs on B cell proliferation and maturation. Conclusion Plasma from SLE patients negatively modulates the effects of normal MSCs in suppressing lupus B cell proliferation and maturation to affect the therapeutic effect of MSC transplantation for treatment of SLE. Double filtration plasmapheresis may therefore prove beneficial to enhance the therapeutic effects of MSC transplantation for SLE.
