Summary

Asthma damages airway epithelium, impairing barrier function and mucus clearance. Eosinophils are increasingly recognized as key contributors to this epithelial damage in asthma.

Area of Science:

  • Pulmonary Medicine
  • Cell Biology
  • Immunology

Context:

  • Asthma involves chronic airway inflammation.
  • Epithelial damage is a key feature of asthma pathology.
  • The role of eosinophils in asthma is under investigation.

Purpose:

  • To review current data on airway epithelial damage in asthma.
  • To describe the structure of normal airway epithelium.
  • To explore the mechanisms by which epithelial damage contributes to asthma.

Summary:

  • Airway epithelial damage in asthma disrupts the physical barrier, alters mucus secretion and mucociliary clearance, and promotes bronchoconstriction.
  • Epithelial cells play active roles in asthma by presenting antigens and recruiting inflammatory cells.
  • There is growing evidence supporting the hypothesis that eosinophils contribute significantly to airway epithelial damage in asthma.

Impact:

  • Understanding epithelial damage mechanisms in asthma can lead to targeted therapies.
  • Identifying the role of eosinophils may reveal new therapeutic targets for asthma.
  • This review highlights the epithelium as both a target and effector in asthma pathogenesis.
