有作者报道,小鼠脾脏来源的NK细胞在体外对弓形虫滋养体具有细胞毒作用。本文运用改良的~(51)Cr释放分析法测定人的NK细胞对弓形虫滋养体是否也具有细胞毒作用。将弓形虫RH株和T_(s-4)株的滋养体用放射性同位素~(51)Cr标记,分别测定抗弓形虫抗体加补体对弓形虫滋养体的溶解作用以及人NK细胞和LAK细胞对弓形虫滋养体及包
It has been reported that mouse spleen-derived NK cells have a cytotoxic effect on Toxoplasma gondii trophozoites in vitro. In this paper, a modified ~ (51) Cr release assay was used to determine whether human NK cells also have cytotoxic effects on Toxoplasma gondii trophozoites. Toxoplasma gondii RH strain and T_ (s-4) strain trophozoites were radiolabeled with radioactive isotope 51 Cr, were measured anti-Toxoplasma antibody plus complement lysis of Toxoplasma trophozoites and human NK cells and LAK cell pairs Toxoplasma gondii and package
