淋巴细胞是机体免疫系统的主要组成部分。人和哺乳类动物的淋巴细胞都有两大类,即 T 细胞与 B 细胞,它们分别担负细胞免疫和体液免疫功能,并与其它因子协同作用,保证机体内部的同质性,这在抵抗病原微生物和抑制肿瘤细胞生成等方面起着重要作用。因此,鉴别不同类型的淋巴细胞,对了解机体的免疫状态发病机理以及免疫理论 Lymphocytes are the major components of the body’s immune system. Human and mammalian lymphocytes have two major categories, namely T cells and B cells, which are responsible for cellular and humoral immune function, and synergistic with other factors to ensure the body’s internal homogeneity, which is resistant to pathogens Microorganisms and inhibit tumor cell generation plays an important role. Therefore, the identification of different types of lymphocytes, to understand the pathogenesis of immune status and immune theory
