人体或动物肿瘤细胞表面具有肿瘤特异性移植抗原,能在宿主体内诱发免疫反应;但由于一般肿瘤细胞的抗原性较弱,只能引起宿主产生一种类似免疫耐受性的反应状态,不能激发有效的抗肿瘤反
Tumor-specific transplanted antigens on the surface of human or animal tumor cells can induce immune responses in the host body. However, due to the weak antigenicity of tumor cells in general, they can only cause the host to produce an immune-like reaction state that can not be stimulated Effective antitumor response
