Antibody-dependent cell cytotoxicity (ADCC) mediated by spleen cells from 30- or 50-day old rats against 51Cr-labelled rat erythrocytes parasitized by Plasmodium berghei in the presence of anti-P. berghei antibody showed only slight age differences. However, in the absence of specific antibody, the total cell-mediated cytotoxicy (CMC) per spleen was four times higher in the spleen cells from 50-day-old rats compared with those from 30-day-old rats. CMC accounted for about 50% of total cytotoxic activity in 50-day-old rat spleens. Spleen cells mediating ADCC and CMC are Thy-1.1 positive, and those mediating ADCC are nearly all non-adherent to Sephadex G-10 columns.
在抗伯氏疟原虫抗体存在的情况下，30日龄或50日龄大鼠的脾细胞介导的针对被伯氏疟原虫寄生的51Cr标记大鼠红细胞的抗体依赖性细胞毒性（ADCC）仅表现出轻微的年龄差异。然而，在没有特异性抗体的情况下，50日龄大鼠脾细胞的每脾总细胞介导细胞毒性（CMC）比30日龄大鼠的脾细胞高四倍。在50日龄大鼠脾脏中，CMC约占总细胞毒性活性的50%。介导ADCC和CMC的脾细胞是Thy-1.1阳性的，而介导ADCC的细胞几乎都不黏附于葡聚糖凝胶G-10柱。
