人类肿瘤细胞表面有无特异性抗原,尚未定论,但已证明有许多瘤细胞表面有肿瘤相关抗原(Tumor-associated antigen,TAA),某些实验动物肿瘤细胞表面现已被证明存在特异性抗原,称为肿瘤特异性移植抗原(Tumor-specific transplantationantigen,TSTA)。但由于其抗原性较弱,带瘤机体也难以产生很强的抗肿瘤细胞的特异性免疫。为了提高肿瘤细胞的抗原性,以提高带瘤机体的抗肿瘤特异性免疫功能,许 There are no specific antigens on the surface of human tumor cells. However, it has been proved that there are many tumor-associated antigens (TAA) on the surface of tumor cells. Some experimental animals have been proved to have specific antigens on the surface of tumor cells, Called tumor-specific transplantation antigen (Tumor-specific transplantationantigen, TSTA). However, due to its antigenicity is weak, the tumor-bearing body is also difficult to produce a strong anti-tumor cell-specific immunity. In order to improve the antigenicity of tumor cells, in order to enhance the anti-tumor-specific immune function of the tumor-bearing body, Xu
