Abstract

Patients affected by obstructive pulmonary diseases exhibit typical characteristics of airway mucus hypersecretion, including sputum production, in- creased luminal mucus, goblet cell hyperplasia and submucosal gland hypertrophy. The mucociliary system is a sophisticated defense mechanism to maintain the homeostasis of the respiratory tract by means of the bronchial mucus transport, the process in which airway mucus together with substances trapped within are moved out of the lungs. In the end, the mucus together with the substances trapped within are swallowed or coughed up. It is an impor- tant defense mechanism of the human body. [...]
