人体末梢T淋巴细胞可经植物血凝素(PHA)等非特异性刺激剂或特异抗原的刺激,在体内或体外发生形态上及生化性质上的改变,转化为代谢旺盛、体积增大并进行分裂的不成熟的淋巴母细胞,参与细胞免疫反应,根据转化为母细隐数量的多少以推测细胞免疫力的程度。目前国内、外已用于测定某些慢性传染病、肿瘤或免疫缺陷病等 T lymphocytes in human peripheral T cells may undergo morphological and biochemical changes in vivo or in vitro stimulated by non-specific stimulators such as phytohemagglutinin (PHA) or specific antigens to convert into metabolically exuberant, enlarged and split Of immature lymphoblasts, involved in cellular immune response, according to the number of mother into the number of hidden in order to infer the degree of cellular immunity. At present, both at home and abroad have been used to determine some chronic infectious diseases, tumors or immunodeficiency diseases
