人体外周血T淋巴细胞和羊红细胞形成的E玫瑰花环,在37℃长时间孵育下即容易分离,但由“活化的”T细胞所形成的“稳定”E花环却能抵抗37℃长时间的孵育而不致解离。作者最近的研究证实了稳定E花环不但能由外周血淋巴细胞(PBL)长时期接触刀豆素A(ConA)而形成,并且也能由仅仅1小时的短时接触ConA而形成。不过这一现象需要有量的依赖,用最大浓度的
E-rosette formed by human peripheral blood T lymphocytes and sheep erythrocytes is easy to isolate when incubated at 37 ℃ for a long time, but the “stable” E-rings formed by “activated” T cells are able to resist the long-term Incubation without dissociation. Recent author’s research confirms that stable E-rosette can be formed not only by prolonged exposure of peripheral blood lymphocytes (PBLs) to concanavalin A (ConA), but also by short-term exposure to ConA for only 1 hour. However, this phenomenon requires a large amount of dependence, with the maximum concentration
