Interleukin 4 (IL-4) expresses multiple biologic activities, including B cell, mast cell, and T cell stimulation. We showed that the incubation of resting splenocytes from C57BL/6 mice solely in purified native or recombinant mouse IL-4 results in the generation of lymphokine-activated killer (LAK) activity directed against fresh, syngeneic sarcoma cells. The precursor activated by IL-4 expresses surface asialo-GM1. In addition, IL-4 is capable of amplifying the splenic LAK activity induced by recombinant IL-2. The generation, by IL-4, of killer cells with broad antitumor reactivity raises the possibility of using IL-4 alone or in combination with IL-2 in the immunotherapy of cancer in animal models.
白细胞介素4(IL-4)具有多种生物学活性,包括刺激B细胞、肥大细胞和T细胞。我们发现,将C57BL/6小鼠的静止脾细胞仅在纯化的天然或重组小鼠IL-4中孵育,会产生针对新鲜同基因肉瘤细胞的淋巴因子激活的杀伤(LAK)活性。被IL-4激活的前体细胞表达表面去唾液酸GM1。此外,IL-4能够增强重组IL-2诱导的脾脏LAK活性。IL-4产生具有广泛抗肿瘤反应性的杀伤细胞,这增加了在动物模型癌症免疫治疗中单独使用IL-4或与IL-2联合使用的可能性。
