Summary

The bronchial epithelium performs mechanical functions and regulates airway responses. Abnormalities in its structure and function may contribute to increased bronchial responsiveness in asthma.

Background:

The bronchial epithelium is crucial for airway defense and mechanical functions like mucociliary clearance.
It plays a role in modulating airway smooth muscle and immune cell activity.

Purpose of the Study:

To explore the potential role of bronchial epithelial abnormalities in the development of increased bronchial responsiveness in asthma.

Main Methods:

This study is a review of existing literature and proposed mechanisms.
Focuses on the functional and structural aspects of the bronchial epithelium.

Main Results:

The bronchial epithelium has mechanical functions including mucociliary clearance and protection.
It modulates smooth muscle function and regulates immune cells (lymphocytes, mast cells).

Conclusions:

Structural and functional abnormalities of the bronchial epithelium may contribute to increased bronchial responsiveness in asthmatic subjects through various mechanisms.
