溶组织阿米巴提出液(E.H.e)中含有对 T 细胞的有丝分裂原。为了进一步研究 E.h.e对 T 细胞亚群的有丝分裂作用,将纯化的 T4~+及 T8~+亚群细胞分别与 E.h.e 温育,以~3H-TdR掺入为指标,观察各细胞亚群对 E.h.e 的增殖反应,结果发现仅 T4~+细胞对 E.h.e 有增殖反应,说明 E.h.e 中含有的有丝分裂原分子具有对 T4~+亚群特异性。实验还证明,E.h.e 刺激 T4~+细胞增殖是通过 IL2来实现的。 Entamoeba histolytica (E.H.e) contains mitogen for T cells. In order to further study the mitotic effect of Ehe on T cell subsets, purified T4 ~ + and T8 ~ + subpopulations were incubated with Ehe respectively. The incorporation of ~ 3H-TdR was used as an indicator to observe the effect of Ehe Proliferation reaction, and found only T4 ~ + cells have a proliferative response to Ehe, indicating that Ehe contains mitogen molecules with T4 ~ + subgroup specific. Experiments also show that E.h.e stimulate T4 ~ + cell proliferation through IL2 to achieve.
