OKT系列单克隆抗体的产生,促进了人T细胞亚类的划分。最初的报道认为,人的外周血T细胞可分为OKT_4~+(T_4~+)和OKT_8~+(T_8~+)细胞两个亚类,分别占T细胞总数的55～65%和30～40%。最近有报道指出,人的末梢血中存在少量的T_4~+T_8~+双标记细胞,在体外活化的T细胞,可以暂时
OKT series of monoclonal antibodies to promote the division of human T cell subsets. Initial reports suggest that human peripheral blood T cells can be divided into two subtypes of OKT_4 ~ + (T_4 ~ +) and OKT_8 ~ + (T_8 ~ +) cells, accounting for 55-65% of the total T cells and 30 ~ 40%. Recently it has been reported that there is a small amount of T_4 ~ + T_8 ~ + double labeled cells in human peripheral blood, and T cells activated in vitro can be temporarily
