淋巴细胞亚群的研究是免疫学研究中一个重要方面,已经显示淋巴细胞有 T 淋巴细胞、B 淋巴细胞、K 细胞等亚群,这些细胞表面都有特征性表面标志。近年亦注意到有些淋巴细胞表面不但有 T 淋巴细胞表面特征,亦同时有 B 细胞或 K 细胞表面特征,这些称为双重标志淋巴细胞。 Studies of lymphocyte subsets are an important aspect of immunological research and have shown that lymphocytes have subsets of T lymphocytes, B lymphocytes, and K cells, all of which have characteristic surface markers on their surfaces. In recent years, it has also been noted that some lymphocyte surfaces not only have the surface features of T lymphocytes, but also have the surface features of B cells or K cells. These are called dual-labeled lymphocytes.
