测定T细胞亚群是现代免疫学的进展。 Tγ(抑制性T细胞)细胞数量减少或者功能减低是引起变态反应,自家免疫的关键因素之一;在另一方面,Tγ细胞数增加或机能亢进,在免疫缺陷疾病和大多数肿瘤的发病上,起着重要作用,在大多数恶性肿瘤中Tγ细胞增加,表明Tγ细胞可能参与肿瘤细胞变化的过程。 The determination of T-cell subpopulations is a development of modern immunology. The decrease of Tγ (inhibitory T cells) or reduced function of cells is one of the key factors causing allergy and home immunity. On the other hand, the number of Tγ cells is increased or hyperfunction, in immunodeficiency diseases and the incidence of most tumors. Plays an important role in the increase of Tγ cells in most malignant tumors, indicating that Tγ cells may be involved in the process of tumor cell changes.
