免疫治疗的理论基础化学物质、蛋白质、病毒或细菌都可以作为一种抗原,当它与免疫活性宿主细胞作用后,发生免疫反应,结果产生与此抗原相对应的特异抗体。抗体免疫反应有两种类型,其一为体液免疫反应,机体所产生的抗体可中和抗原;第二种称为细胞免疫反应,淋巴细胞一方面可被特异抗原致敏,并附着其上,最终导致其裂解;又淋巴细胞产生化学物质淋巴激活素(lymphokines)亦可促使其破坏。与免疫反应有关的淋巴细胞有B 和T 细胞两种类型。B 细胞对细菌病原体起免疫反应;T 细胞则与病
The theoretical basis of immunotherapy Chemical substances, proteins, viruses, or bacteria can all be used as an antigen. When it interacts with immune-competent host cells, an immune reaction takes place. As a result, specific antibodies corresponding to the antigen are produced. There are two types of antibody immune response, one is humoral immune response, antibodies produced by the body can neutralize antigens, and the second is called cellular immune response. Lymphocytes can be sensitized and attached to specific antigens on the other hand. It eventually leads to its lysis; lymphocyte production chemicals lymphokines can also promote its destruction. There are two types of lymphocytes associated with immune responses: B and T cells. B cells are immune to bacterial pathogens; T cells are associated with disease
