To get more information on the mechanism of cell-mediated immunodeficiency associated with Down's syndrome, 18 patients were studied for PHA-induced lymphocyte transformation and interleukin-2 (IL-2) production. A normal amount of IL-2 was produced although half of the patients showed decreased blast transformation. T cell subpopulations were studied in some patients with decreased and with normal blast transformation. All studied patients with decreased blast transformation had inverted helper/suppressor T cell ratio.
为了获取更多关于与唐氏综合征相关的细胞介导免疫缺陷机制的信息,对18名患者进行了PHA诱导的淋巴细胞转化和白细胞介素-2(IL-2)产生的研究。尽管一半的患者显示出母细胞转化减少,但仍产生了正常量的IL-2。对一些母细胞转化减少和正常的患者进行了T细胞亚群研究。所有母细胞转化减少的研究患者均有辅助/抑制性T细胞比例倒置的情况。
