A significant increase in CD25 antigen-positive cells by IL-1 was observed in cells of a patient with M7 acute myelogenous leukemia. Basal proliferation and expression of CD25 antigen by the M7 leukemic cells were inhibited by addition of anti-IL-1 beta antibody in a dose-dependent manner, but not by rabbit anti-IL-1 alpha antibody. Culture supernatants of these leukemic cells contained IL-1 activity, which was specifically inhibited by addition of anti-IL-1 beta antibody, and Northern blot analysis detected intracellular IL-1 beta mRNA. These results indicated that autocrine secretion of IL-1 beta was involved in proliferation of some myelogenous leukemic cells.
在一名M7型急性髓性白血病患者的细胞中,观察到IL-1使CD25抗原阳性细胞显著增加。添加抗IL-1β抗体可剂量依赖性抑制M7白血病细胞的基础增殖和CD25抗原表达,但兔抗IL-1α抗体无此作用。这些白血病细胞的培养上清液含有IL-1活性,添加抗IL-1β抗体可特异性抑制该活性,Northern印迹分析检测到细胞内IL-1β mRNA。这些结果表明,IL-1β的自分泌分泌参与了一些髓性白血病细胞的增殖。
