许多研究工作表明,T淋巴细胞不仅是细胞免疫的效应细胞,而且在免疫反应的调节上具有重要的作用。T细胞的免疫调节作用是由T细胞的亚群,尤其是功能上不同的亚群来完成的。因而,T细胞亚群的研究和检测在许多疾病的免疫发病学研究上,以及在免疫性疾病和免疫病理过程的防治研究上都有重要的意义。 Many studies have shown that T lymphocytes are not only effector cells of cellular immunity, but also play an important role in the regulation of immune response. The immunomodulatory effect of T cells is accomplished by subsets of T cells, especially functionally distinct subsets. Therefore, the research and detection of T cell subsets are of great significance in the immunophenotyping of many diseases and in the prevention and treatment of immune diseases and immunopathological processes.
