| Airway Mucus Production
Aliases:
Airway Mucus Content; Mucus Hypersecretion; Bronchial Mucus Production;
Airway Mucus Accumulation
Definition:
Airway mucus production refers to the secretion and accumulation of mucus
within the respiratory tract. Mucus is produced primarily by goblet cells and
submucosal glands and contains mucins such as MUC5AC and MUC5B.
Asthma relevance:
Excessive mucus production is a major feature of asthma and contributes to
airway narrowing, mucus plugging, impaired airflow, and exacerbations.
Experimental asthma studies commonly assess airway mucus using histological
staining, mucus scores, goblet-cell staining, or mucin expression.
Direction:
Airway Mucus Production ↑ = generally adverse
Airway Mucus Production ↓ = generally beneficial
Common measurement contexts:
Airway mucus staining; PAS-positive mucus; mucus score; airway mucus content;
bronchial mucus accumulation
Typical pathway:
IL-13 ↑
→ goblet-cell hyperplasia ↑
→ MUC5AC / mucin secretion ↑
→ Airway Mucus Production ↑
→ airway obstruction ↑
