近代免疫学已应用于眼病的诊断和治疗。人体借助两个免疫系统以防御感染和癌瘤:一为细胞免疫,可防御霉菌和病毒,排除癌瘤和异物(包括移植组织)。二为体液免疫,可防御细菌和病毒的再感染。二者可起协同作用。两个免疫系统与两类淋巴细胞(T-和 B-淋巴细胞)有关。二者来源于同一造血细胞(骨髓干细胞),早期形态相似,但免疫作用不同。小鸡法氏囊及哺乳动物的同等结构产生的细胞叫作B 细胞,能产生抗体。自胸腺释放到周围组织中的淋巴细胞叫作 T 细胞,存在于胸腺内的淋巴细
Modern immunology has been used in the diagnosis and treatment of eye diseases. The body uses two immune systems to fight infections and cancers: one is cellular immunity that protects against mold and virus and eliminates cancers and foreign bodies, including transplanted tissue. Second, humoral immunity, can prevent bacterial and viral re-infection. Both can play a synergistic role. Two immune systems are associated with two types of lymphocytes (T- and B-lymphocytes). Both from the same hematopoietic cells (bone marrow stem cells), early morphological similar, but different immune function. The cells produced by the same structure of chicken bursa and mammals are called B cells and produce antibodies. Lymphocytes released into the surrounding tissue from the thymus are called T cells, lymphocytes present in the thymus
