肿瘤免疫研究表明,机体对肿瘤的免疫作用主要是细胞免疫。Klein等(1960)将肿瘤细胞与免疫动物的淋巴细胞一起在体外处理以后,就减弱了瘤细胞在宿主中生长的能力。Alexander和Delorme等(1964,1966)注射同种或异种的免疫淋巴细胞,使化学物质诱发的大鼠原发性纤维肉瘤得到缓解或消退。近年来,许多实验证明,脾脏细胞、局部淋巴结细胞、胸导管淋巴细胞和腹膜表面的淋巴细胞都是能够传递肿瘤特异
Tumor immunity studies have shown that the body’s immune response to tumors is mainly cellular immunity. Klein et al. (1960) treated tumor cells with lymphocytes of immunized animals in vitro to attenuate the ability of the tumor cells to grow in the host. Alexander and Delorme et al. (1964, 1966) injected homogeneous or heterogeneous immune lymphocytes to allow chemical-induced rat primary fibrosarcoma to resolve or resolve. In recent years, many experiments have shown that spleen cells, regional lymph node cells, thoracic ductal lymphocytes, and lymphocytes on the peritoneal surface are all capable of delivering tumor specificity.
