肿瘤基因治疗的最新途径长期以来肿瘤研究的一个重要目标就是使机体对肿瘤产生免疫排斥作用。其中细胞免疫起着关键性的作用，因此研究如何使Ｔ细胞活化的途径受到了高度重视。最近美国有三个研究小组基于一种淋巴细胞激活的双信号模型的假设，在动物实验中获得了重大成功... The latest approach to cancer gene therapy An important goal of cancer research over a long period of time is to make the body immune to tumor rejection. Among them, cellular immunity plays a key role, so the study of how to make T cell activation has received great attention. Recently, three research groups in the United States have achieved major success in animal experiments based on the assumption of a dual-signal model of lymphocyte activation...
