人体的免疫监视机构包括细胞免疫、体液免疫和补体系统。对肿瘤的免疫反应,以细胞免疫为主。但近几年对体液免疫(包括补体)也日益重视,研究细胞免疫与体液免疫的相互关系,对于进一步深入了解肿瘤发生发展的免疫机制有着重要的意义。 由抗体介导的细胞溶解需要补体的参与,这提示血清总补体的改变与肿瘤的发病有一定关系。近年有不少关于肿瘤病人血清补体研究的报道,但有些结果互相矛盾,而且 Human immune surveillance institutions include cellular immunity, humoral immunity and complement system. The immune response to the tumor, the main cellular immunity. However, humoral immunity (including complement) has also been paid more and more attention in recent years. Studying the relationship between cellular immunity and humoral immunity is of great significance for further understanding of the immune mechanism of tumorigenesis. Antibody-mediated cytolysis requires the involvement of complement, suggesting a change in total complement complementarity with tumor progression. In recent years, there are many reports on the study of serum complement in tumor patients, but some of the results contradict each other, and
