Life Stage Applicability
Key Event Relationship Description
Chronic mucus hypersecretion is a main feature of chronic lung diseases, and the presence of goblet cell hyperplasia or goblet cell metaplasia in the lungs of chronic opbstructive pulmonary disease, asthma and cystic fibrosis patients has been inferred as cause for sustained mucus production (Rose and Voynow, 2006; Munkholm and Mortensen, 2014).
