Supernatants obtained from 3-day cultures of cord blood monocytes inhibited normal lymphocyte activation by either PHA or in a two-way MLC. Both lymphocyte transformation and lymphokine production was significantly inhibited by these supernatants but not by those derived from adult mononuclear cell cultures. The inhibitory material produced by foetal monocytes was dialysable and was non-cytotoxic to target cells. It is postulated that this factor contributes to the depressed maternal cell-mediated immune response observed in pregnancy.
从脐血单核细胞3天培养物中获得的上清液,可抑制由PHA或双向混合淋巴细胞培养(MLC)引起的正常淋巴细胞激活。这些上清液显著抑制淋巴细胞转化和淋巴因子产生,但来自成人单核细胞培养物的上清液则无此作用。胎儿单核细胞产生的抑制物质可透析,且对靶细胞无细胞毒性。据推测,该因子导致了孕期观察到的母体细胞介导免疫反应降低。
