Mechanisms of Mucus Induction in Asthma

  • Lauren Cohn
Part of the Allergy Frontiers book series (ALLERGY, volume 3)


Mucus hypersecretion is a defining feature of asthma and contributes significantly to airway obstruction. The mechanisms by which a normal airway epithelium is converted to a mucus-producing epithelium in asthma are complex. Inflammation in asthma promotes metaplasia of ciliated and Clara cells into goblet cells after both EGFR activation and the effects of IL-13 on Stat6 activation. Recently identified transcription factors and proteins highlight critical steps in the pathway that leads to the transition to a mucus-secreting airway epithelium.
