Asthma involves complex respiratory epithelial changes and impaired repair. Understanding the epithelial-mesenchymal trophic unit (EMTU) interactions is key to developing new asthma treatments.
Area of Science:
- Respiratory Medicine
- Cell Biology
- Immunology
Background:
- Asthma pathophysiology involves atopy and bronchial hyperreactivity.
- Respiratory epithelial alterations are critical in asthma development and persistence.
- Asthmatic airways epithelium shows early, unrepaired alterations.
Purpose of the Study:
- To explore the role of respiratory epithelial alterations in asthma.
- To investigate the epithelial-mesenchymal trophic unit (EMTU) in asthma.
- To identify targets for future asthma prevention and therapy.
Main Methods:
- Review of existing evidence on asthma pathophysiology.
- Analysis of structural and functional changes in airway epithelium.
- Examination of EMTU interactions in asthmatic airways.
Main Results:
- Respiratory epithelial damage and impaired repair are central to asthma.
- The EMTU contributes to self-sustaining airway damage and chronic inflammation.
- Susceptibility factors and environmental factors influence epithelial damage.
Conclusions:
- Epithelial-mesenchymal interactions are crucial in asthma.
- Targeting EMTU may offer new therapeutic strategies for asthma.
- Further research into EMTU, environmental factors, and susceptibility is needed.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
