Human IL-1, recombinant murine IL-1 and E. coli LPS were found to be potent inducers of plasminogen activator (PA)-inhibitor activity, both in vivo, in rats, as well as in cultured human endothelial cells. In vivo, LPS rapidly and dose-dependently (0.01-1,000 micrograms/kg) increased plasma PA-inhibitor activity. Infusion of IL-1 into rats resulted in a small but significant increase in PA-inhibitor activity in rat plasma. Likewise, in cultured human umbilical vein endothelial cells, LPS and IL-1 induced increased synthesis of PA-inhibitor. We suggest that the induced rat plasma inhibitor might be of endothelial origin.
已发现,人白细胞介素-1、重组鼠白细胞介素-1和大肠杆菌脂多糖无论是在大鼠体内还是在培养的人内皮细胞中,都是纤溶酶原激活物(PA)抑制活性的有效诱导剂。在体内,脂多糖在大鼠中迅速且呈剂量依赖性(0.01 - 1000微克/千克)地增加血浆PA抑制活性。向大鼠输注白细胞介素-1导致大鼠血浆中PA抑制活性有小幅但显著的增加。同样,在培养的人脐静脉内皮细胞中,脂多糖和白细胞介素-1诱导PA抑制剂的合成增加。我们认为诱导产生的大鼠血浆抑制剂可能来源于内皮细胞。
