T细胞是由机能和表面抗原不同的多种类细胞组成.T细胞不仅在移植排斥反应和迟发型变态反应中起效应细胞的作用,而且也调节B细胞向Ig分泌细胞转化.这种免疫应答的调节主要是用小鼠研究的.现已明瞭,具有不同表面抗原的T细胞亚群进行着细胞间复杂的信息传递.Schlcssman等人成功地制备了鉴定人T细胞的单克隆抗体,使这一领域的研究有飞跃的进步,取得了重大的研究成果. T cells are composed of many different types of cells with different functional and surface antigens T cells act not only as effector cells in transplant rejection and delayed type allergy but also in the regulation of B cell transformation to Ig secreting cells Modulation is primarily studied in mice, and it is now known that T-cell subsets with different surface antigens undergo complex cell-to-cell information delivery.Schlcssman et al. Successfully prepared monoclonal antibodies to identify human T cells, Research has made leaps and bounds, has made significant research results.
