Mucus Secretion in Airway Epithelium

Molecular classification
Other
01

Overview

Mucus secretion in the airway epithelium is a tightly regulated process involving goblet cells, submucosal gland cells, and club cells that produce and secrete mucins (MUC5AC and MUC5B). This secretion is crucial for trapping and removing inhaled particles and pathogens. Dysregulation can lead to diseases characterized by mucus hypersecretion and impaired airway clearance.
