美国约翰·霍普金斯大学的研究人员发现,将分泌高水平IL-4的基因工程肿瘤细胞注入小鼠体内后可诱导小鼠的免疫系统杀伤同类型的癌细胞,这种方法有可能成为治疗人类肿瘤的基因疗法。作者首先以带有小鼠IL-4cDNA,并含有 Researchers at Johns Hopkins University in the United States have found that injecting genetically engineered tumor cells that secrete high levels of IL-4 into mice can induce mice’s immune system to kill the same type of cancer cells. This method may become Gene therapy for human tumors. The author first used mouse IL-4 cDNA and contained
