The plasmin/plasminogen system of enzymes may be involved in leukocyte migration through the endothelial cell layer of the vascular wall during inflammatory processes associated with vascular injury, atherosclerosis, and sepsis. Synthesis of plasminogen activator inhibitor type 1 (PAI-1) by the endothelium may protect these cells and the subendothelial cell matrix from excessive degradation and retard leukocyte migration. We report in this work for the first time the down-regulation of both basal and thrombin- or endotoxin-induced PAI-1 in cultured human endothelial cells by the activated T cell product, IFN-gamma. Down-regulation of basal and thrombin- or endotoxin-induced endothelial PAI-1 protein by IFN-gamma was found to be both time and dose dependent. Decreases of up to 71% relative to thrombin- or endotoxin-treated controls, using an optimal IFN-gamma concentration of between 20 and 200 U/ml, were found for human macrovascular and microvascular endothelial cells. However, IFN-gamma did not appear to affect IL-1 alpha- and TNF-alpha-induced levels of PAI-1 protein or mRNA in these cells. Northern blot analysis paralleled protein results, showing decreases in specific endothelial cell thrombin- or LPS-induced PAI-1 mRNA expression, respectively, after incubation with IFN-gamma for 24 h. These results suggest a means by which the migration of circulating leukocytes through endothelial cell layers during inflammation may be facilitated.
