Matrix metalloproteinases in asthma and COPD

Abstract

Asthma and chronic obstructive pulmonary disease (COPD) are both highly prevalent, chronic inflammatory lung diseases that lead to significant morbidity and mortality. Matrix metalloproteinases (MMPs) are extracellular matrix degrading enzymes that play a critical role in normal development and physiological tissue remodeling and repair. In addition, they play an important role in the regulation of the kinetics and function of inflammatory cells. There is increasing evidence that MMPs are involved in the pathogenesis of both asthma and COPD, and several MMPs are possible therapeutic targets in these common chronic airway diseases.
