title: The 'PAI-1 paradox' in vascular remodeling.
abstract: Vascular remodelling is a complex phenomenon associated with restructuring of the vessel wall as a consequence of disruption of vascular homeostasis. Alterations of the vascular wall have been linked to a variety of cardiovascular disorders including atherosclerosis, vascular injury and pulmonary hypertension. Plasminogen activator inhibitor-1 (PAI-1) is a member of the serpin (serine proteinase inhibitor) family and acts as an important inhibitor of fibrinolysis by interfering with the plasminogen system. In addition to its anti-fibrinolytic effects, PAI-1 appears to modulate cellular responses linked to vascular remodelling. Since PAI-1 levels have been shown to be altered in various disorders associated with vascular remodelling of the systemic and pulmonary vascular bed, this serpin may play a pivotal role in the pathogenesis of these diseases.
