Abstract

The plasminogen activation system (PAS) and the plasmin it forms have dual roles in chronic respiratory diseases including asthma, chronic obstructive pulmonary disease and interstitial lung disease. Whilst plasmin-mediated airspace fibrinolysis is beneficial, interstitial plasmin contributes to lung dysfunction because of its pro-inflammatory and tissue remodeling activities. Recent studies highlight the potential of fibrinolytic agents, including small molecule inhibitors of plasminogen activator inhibitor-1 (PAI-1), as treatments for chronic respiratory disease. Current data also suggest that interstitial urokinase plasminogen activator is an important mediator of lung inflammation and remodeling. However, further preclinical characterization of uPA as a drug target for lung disease is required. Here we review the concept of selectively targeting the contributions of PAS to treat chronic respiratory disease.
