本文介绍了用自制的IL_2(白介素Ⅱ)和粗提的lL2(?)(?)导LAK(淋巴因子活化杀伤细胞)的生成。用大鼠脾细胞制备IL_2乳腺癌小鼠脾细胞作为诱导LAK的单个核细胞。初步结果显示:1.IL_2培养上清能诱导出LAK样增殖特性。2.IL_2的粗提物可使LAK增殖作用增强。3.IL_2可使活化的和未活化的淋巴细胞同样增值。
This article describes the production of LAK (lymphokine activated killer cells) using home-made IL-2 (interleukin II) and crude lL2 (?) (?). IL-2 breast cancer mouse spleen cells were prepared using rat spleen cells as LAK-inducing mononuclear cells. Preliminary results showed that: 1. IL 2 culture supernatant can induce LAK-like proliferation characteristics. 2. The crude extract of IL 2 can enhance the proliferation of LAK. 3. IL 2 can increase the same amount of activated and unactivated lymphocytes.
