It was found that spleen cells from mice injected i.v. with large doses of BCG respond to PHA stimulation less intensely than do normal spleen cells. We were able to show that nylon wool column purified BCG treated T cells also had a low PHA reactivity. Unfractionated spleen cells, adherent cells or T-enriched populations from BCG treated mice, when added to normal T cells lowered their PHA reactivity. When the same BCG treated cell populations were added to tumor cells in vitro, they inhibited their growth.
结果发现,经静脉注射大剂量卡介苗的小鼠的脾细胞对PHA刺激的反应不如正常脾细胞强烈。我们能够证明,经尼龙毛柱纯化的卡介苗处理的T细胞对PHA的反应性也很低。来自卡介苗处理小鼠的未分离脾细胞、贴壁细胞或富含T细胞的群体,当添加到正常T细胞中时,会降低它们对PHA的反应性。当将相同的卡介苗处理的细胞群体在体外添加到肿瘤细胞中时,它们会抑制肿瘤细胞的生长。
