目的 研究四嗪二甲酰胺(ZGDHu-1)对植物血凝素(PHA)刺激的T淋巴细胞体外活化的影响,初步探讨其免疫抑制作用.方法 从健康人外周血分离淋巴细胞,经PHA刺激诱导淋巴细胞活化,ZGDHu-1单独或联合环孢霉素A(CSA)作用24 h、48 h,检测各组T淋巴细胞的增殖、凋亡情况.采用流式细胞仪检测CD3~+ CD69~+、CD3~+ CD25~+、CD4~+ CD25~+、CD8~+ CD25~+和CD3~+ Fas~+、CD4~+ Fas~+、CD8~+ Fas~+.用Annexin V/PI染色结合流式细胞术,分析淋巴细胞早期凋亡.酶联免疫吸附法(ELISA)检测细胞培养上清IL-2和转化生长因子-β1(TGF-β1).结果 ZGDHu-1能明显降低PHA活化的CD3~+ CD69~+、CD3~+ CD25~+、CD4~+ CD25~+和CD3~+ Fas~+、CD4~+ Fas~+、Annexin V~+/PI~-,并降低活化T淋巴细胞的IL-2分泌及促进TGF-β1的分泌,联合CSA应用效果更明显.结论 ZGDHu-1能抑制T淋巴细胞活化,降低T淋巴细胞凋亡,和CSA联合具有一定的协同效应.

Objective To investigate the effects of ZGDHu-1 on T lymphocytes activation in vitro to elucidate its immunosuppressive effects. Methods Lymphocytes isolated from healthy persons were stim-ulated with phytohanmagglutinin(PHA) and different experimental groups were set by cocultured for 24 h, 48 h with ZGDHu-1 or with ZGDHu-1 and Cyclosporin A(CSA). To assess the proliferation and apoptosis of T lymphocytes, we detected CD3~+ CD69~+ , CD3~+ CD25~+ , CD4~+ CD25~+ , CD8~+ CD25~+ and CD3~+ Fas~+, CD4~+ Fas~+ , CD8~+ Fas~+ with flow cytometry. The early apoptosis rate of lymphocytes was analyzed with flow cytometry. Culture supernatant IL-2 and TGF-β1 were detected with ELISA. Results ZGDHu-1 decreased PHA activative CD3~+ CD69~+, CD3~+ CD25~+, CD4~+ CD25~+ and CD3~+ Fas~+, CD4~+ Fas~+, Annexin V~+/ PI~- and inhibited IL-2 secretion and promoted TGF-β1 secretion respectively. ZGDHu-1 has synergistic effect with CSA to be more obvious. Conclusion ZGDHu-1 can inhibit T lymphocytes activation and de-creased apeptosis of T lymphocytes. ZGDHu-1 has synergistic effect with CSA to be obvious.
