Tumor necrosis factor induces the production of urokinase-type plasminogen activator by human endothelial cells

Endothelial cells play an important role in the regulation of fibrinolysis by the production of several key regulatory proteins. The cytokines tumor necrosis factor (TNF), lymphotoxin, and interleukin-1 (IL-1), but not interleukin-6, increase the production of plasminogen activator inhibitor-1 (PAI-1) by endothelial cells, whereas they have no...

Tumor necrosis factor increases the production of plasminogen activator inhibitor in human endothelial cells in vitro and in rats in vivo

The vascular endothelium plays an important role in fibrinolysis by producing tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI). The monokine tumor necrosis factor (human recombinant TNF) increased the production of PAI by cultured human endothelial cells from umbilical vein (twofold) and from foreskin...
