Effector cells for cell-mediated lysis (CML) were generated by in vitro culture of lymphocytes from selected donors with X-irradiated cells from unrelated subjects who were HLA-D homozygous and matched to the responders for the antigens of the HLA-A and HLA-B regions. By using chromium labeled monocytes as target cells, cytotoxicity was found to correlate with presence of HLA-D region antigens matching those of the stimulating cells. Such CML reactions apparently directed at products of HLA-D, were inhibited by addition of unlabeled monocytes or B lymphocytes. These unlabeled cells had to be matched for HLA-D with the stimulating cells used to generate the effector populations. The results suggested that products of HLA-D, perhaps the DR antigens, were recognized by cytotoxic lymphocytes.
通过用来自无关个体的经X射线照射的细胞对选定供体的淋巴细胞进行体外培养,生成了用于细胞介导溶解(CML)的效应细胞。这些无关个体为HLA - D纯合子,且在HLA - A和HLA - B区域的抗原与应答者相匹配。以铬标记的单核细胞作为靶细胞,发现细胞毒性与刺激细胞的HLA - D区域抗原的存在相关,这些抗原与刺激细胞的相匹配。这种明显针对HLA - D产物的CML反应,可通过添加未标记的单核细胞或B淋巴细胞而受到抑制。这些未标记的细胞在HLA - D方面必须与用于产生效应细胞群体的刺激细胞相匹配。结果表明,细胞毒性淋巴细胞能够识别HLA - D的产物,可能是DR抗原。
