Abstract
Chronic obstructive pulmonary disease (COPD) is a major health problem worldwide, and we have little specific therapy to offer these patients. One potential strategy to limit loss of lung function in COPD would be to inhibit matrix-degrading proteinases. Several serine proteinases and matrix metalloproteinases are expressed in association with COPD in humans. Application of gene-targeted macrophage elastase and neutrophil elastase to a mouse model of cigarette-smoke-induced emphysema has uncovered roles for these proteinases in airspace enlargement, and has identified many interactions between these proteolytic systems.
