根据分化抗原不同,通常可以将人外周血淋巴细胞分成OKT4~+和OKT8~+两个亚群(简称T4~+和T8~+)。一般认为T4~+亚群具有辅助和诱导功能(T_H/T_i),T8~+亚群具有抑制和细胞毒功能(T_S/TC)。近年来,由于单克隆抗体技术的发展,已获得了一些新的人T细胞单克隆抗体(下称 According to the differentiation of different antigens, usually can be divided into OKT4 ~ + and OKT8 ~ + two subpopulations (referred to as T4 ~ + and T8 ~ +) of human peripheral blood lymphocytes. It is generally believed that T4 ~ + subpopulation has auxiliary and inductive functions (T_H / T_i) and T8 ~ + subpopulation has inhibitory and cytotoxic functions (T_S / TC). In recent years, due to the development of monoclonal antibody technology, some new human T cell monoclonal antibodies have been obtained
