近一二十年来,由于免疫学的迅速发展,对细胞免疫和体液免疫有了进一步的了解。一般认为,细胞免疫主要担负着肿瘤性疾患、病毒性疾病、霉菌性感染和某些细胞内寄生性细菌所致疾病的免疫。细胞免疫的细胞学基础是胸腺依赖淋巴细胞(T细胞)。当其在体内受到适宜抗原的刺激,则在引流部位淋巴结的胸腺依赖区发生胚变和增殖,产生大量对该抗原具有特异性的免疫淋巴细胞;当其与原抗原接触时,则发生细胞毒作用和释放一系列的淋巴
In the recent one or two decades, due to the rapid development of immunology, further understanding of cellular and humoral immunity has been obtained. It is generally believed that cellular immunity is primarily responsible for the immunity of neoplastic disorders, viral diseases, fungal infections and diseases caused by certain intracellular parasitic bacteria. Cytological basis of cellular immunity is thymus dependent lymphocytes (T cells). When it is stimulated in the body by suitable antigens, embryogenesis and proliferation occur in the thymus-dependent region of the lymph node in the drainage site, producing a large number of immune lymphocytes that are specific for the antigen; cytotoxicity occurs when it contacts the antigen Function and release a series of lymph
