【摘要】 某些抗癌药物的免疫调节效应在其抗肿瘤机制中可能起着重要作用.本研究表明,低浓度(0.04mg·L~-1)阿霉素对人胚胸腺细胞IL-2产生和LAK活性的诱导具有促进作用;高浓度(4mg·L~-1)阿霉素虽对LAK活性没有影响,但却明显抑制IL-2的产生.提示低浓度阿霉素对人胚胸腺细胞具有一定的免疫增强效应.更多还原

【Abstract】 The immunoregulatory effects of some anti-cancer drugs have important role in their anti-tumor mechanisms. Our results showed that doxorubicin (DXR) of 0.04 mg ?L-1 could enhance the interleukin 2 (IL-2) release and induction of lymphokine-activated killer (LAK) activity of human fetal thymocytes(HFT). Higher concentration of this drug (4 mg ?L-1) exhibited inhibition on IL-2 release but no effect on LAK activity. These data suggest that lower concentration of DXR have some immunopotentiation effects on HFT.更多还原
