摘要
目的研究IL-2-PE40对免疫活性T细胞的影响。方法采用ConA刺激的淋巴细胞增殖试验、混合淋巴细胞培养(MLC)及细胞毒试验。结果IL-2-PE40对ConA诱导的小鼠脾细胞有十分强的细胞毒性,能选择性地抑制MLC中抗原活化的T细胞活性,保留未活化T细胞对ConA诱导的丝裂原反应,在培养d3加入IL-2-PE40比培养开始时加入对MLC抑制作用强。结论IL-2-PE40能够高度选择性抑制免疫活性T细胞,是IL-2R靶向治疗中具有潜力的一种免疫抑制剂。
AIM To study the effect of IL2PE 40 on activated T lymphocyte. METHODS Lymphocyte proliferation assay, mixed lymphocyte culture (MLC) and cytotoxicty assay were used. RESULTS The in vitro experiment showed that IL2PE 40 was extremely toxic for Con Astimulated spleen cells from mice,and could suppress Agactivated lymphocyte and the generation of cytotoxic T lymphocyte activity in a MLC while leaving to Con A inducible mitogenic response of the nonactivated lymphocyte. The inhibitory effect was greater when the IL2 toxin was added on day 3 as compared with day 0 of MLC. CONCLUSION Our study suggested that IL2PE 40 can selectively inhibites activated T lymphocyte, which is a potent immunosuppressive agent in IL2R targeting.
