摘要:
Elevated plasma concentrations of plasminogen activator inhibitor type 1 (PAI-1), also named serpin E1, are encountered in patients with thrombophilia, atherosclerosis, septicemia and the metabolic syndrome and may be associated with an increased risk of complications. Expression of PAI-1 is increased by inflammatory stimuli and decreased by statins, drugs widely used in patients with cardiovascular disease. Increased expression of PAI-1 by inflammatory stimuli is mediated by a large variety of signal transduction pathways, which include the NF-kappa B and MAP kinase pathways. The downregulating effect of statins on PAI-1 expression is dependent on the inhibition of Rho family proteins and may involve an activation of PI-3 kinase/Akt signaling pathways. In this review we summarize the findings on the effect of inflammation and statins on PAI-1 expression.
