Airway mucin concentration as a marker of chronic bronchitis
Pulmonary Disease, Chronic Obstructive
Airway mucin concentrations may quantitate a key component of the chronic bronchitis pathophysiologic cascade that produces sputum and mediates disease severity. Studies designed to explore total mucin concentrations in sputum as a diagnostic biomarker and therapeutic target for chronic bronchitis appear to be warranted.
