[肿瘤免疫的一般概念] 一、肿瘤抗原问题: 动物实验证明,化学致癌剂所致肿瘤,各肿瘤抗原各不相同,同一种病毒诱发的不同肿瘤或不同个体的肿瘤有共同的抗原。现在的研究发现,此结论不是绝对的。至于人类肿瘤是否存在特异性抗原问题,研究很多,意见尚不统一。多是间接地通过体液免疫或细胞免疫的方法证明某些肿瘤存在某些异常的抗原成份,可能在一定程度上反映肿瘤的特性或病因关系,但由于分离和提出抗原的困难,常
[General Concepts of Tumor Immunity] 1. Tumor antigen problems: Animal experiments have shown that tumors caused by chemical carcinogens are different from each other in tumor antigens, and that the same virus induces different tumors or tumors of different individuals have common antigens. The current study found that this conclusion is not absolute. As to whether there are specific antigens in human tumors, there are many studies and opinions are not uniform. Most of them indirectly prove the presence of certain abnormal antigen components in certain tumors by humoral or cellular immunity, which may reflect the characteristics of the tumor or the etiology of the tumor to a certain extent. However, due to difficulties in the isolation and presentation of antigens, often
