雷公藤多甙对急性移植物抗宿主病小鼠细胞因子的影响

Effects of glucosidorum tripterygii tororum on cytokine productions in graft-versus-host disease mice

目的 :观察雷公藤多甙对骨髓移植时移植物抗宿主病 (aGVHD)小鼠血清IL - 2、TNFα、IL - 4和IL -10浓度的影响 ,探讨雷公藤多甙抗aGVHD的作用机制。方法 :应用直线加速器排空C57BL/6小鼠骨髓后 ,注入BALB/C小鼠骨髓与脾淋巴细胞的混合液 ,复制出aGVHD模型。应用ELISA法检测经雷公藤多甙、环孢素A(CsA) +氨甲喋呤 (MTX)和雷公藤多甙 +CsA处理后 ,受鼠血清中IL - 2、TNFα、IL - 4和IL - 10浓度。结果 :①雷公藤多甙组小鼠 11d的生存率 (9/10 )高于异基因骨髓移植组 (8/19) ;②雷公藤多甙组小鼠血清中IL - 2、TNFα的浓度明显低于异基因骨髓移植组 (P <0 0 5 ) ;IL - 10的浓度明显高于异基因骨髓移植组 (P <0 0 5 ) ,IL - 4的浓度变化不明显 (P >0 0 5 )。结论 :雷公藤多甙可能通过调节促炎 /抑炎细胞因子的分泌 ,而发挥其明显的抗aGVHD作用。

AIM: To observe the effect of glucosidorum tr ipterygii tororum (GTT) on cytokine productions in acute graft-versus-host disea se (aGVHD) mice. METHODS : C 57 BL/6 mice were exposed to radiation delivered by a linear accelerator . To es tablish a aGVHD model, the cell suspensions, which were obtained from bone marro w and spleen of the BALB/C mice, were transplanted to the radiated C 57 BL/6 mice. The recipients were treated with GTT, GTT+CsA and CsA+MTX. The serum conc entrations of IL-2, TNF-α, IL-4 and IL-10 were determined by ELISA. RES ULTS: The survival rate on day 11 in GTT group (9/10) was higher than in allogeneic bone marrow transplatation (allo-BMT) group (8/19). The concentratio ns of IL-2 and TNF-α in GTT group were significantly lower, but the concentrati on of IL-10 was remarkably higher than that in allo-BMT group ( P <0 05). H owever, the concentration of IL-4 showed no changed in all groups ( P >0 0 5). CONCLUSION: GTT inhibited aGVHD development by regulating th e production of cytokines in the host.
