随着免疫学的进展、人们逐渐注意到参与细胞免疫的T细胞并不是均一的细胞群。按其发育阶段、表面标志及功能等、可将其分为若干亚群。T细胞亚群不仅在抗体产生上起着调节作用,而且在自身免疫病、免疫缺陷病、变态反应性疾病、再生不良性贫血、器官移植及肿瘤发生等方面均有重要影响,故开展T细胞亚群的研究是很有意义的。 As immunology progresses, people are gradually noticing that T cells involved in cellular immunity are not homogeneous cell populations. According to their developmental stages, surface markers and functions, it can be divided into several subgroups. T cell subsets not only play a regulatory role in antibody production, but also have important effects in autoimmune diseases, immunodeficiency diseases, allergic diseases, aplastic anemia, organ transplantation and tumorigenesis, etc. Therefore, the development of T cells Sub-group research is very meaningful.
