At present, the specific mechanism of airway remodeling is unknown. Airway abnormalities found by chest CT often indicate that airway remodeling has occurred in patients.

Studies have shown that the imbalance between matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1) and MMP-9/TIMP-1 ratio is involved in the airway remodeling of COPD. This paper describes the research progress of MMP-9, TIMP-1 and MMP-9/TIMP-1 ratio as non-invasive diagnostic markers in airway remodeling of COPD. It is expected to improve people’s understanding of early airway remodeling and make a modest contribution to the development of targeted drugs for airway remodeling in the future.展开更多
