Protocol for characterizing airway epithelial ciliary beating and mucociliary transport using image processing and...

Area of Science:

• Pulmonary Science
• Cell Biology
• Biophysics

Background:

• Lung epithelial cilia are vital for respiratory health, facilitating mucociliary transport (MCT).
• Effective MCT clears inhaled pathogens and particulate matter from the airways.
• Dysfunctional ciliary activity is implicated in various respiratory diseases.

Purpose of the Study:

• To present a standardized protocol for measuring ciliary beat frequency (CBF) and MCT.
• To provide a reproducible method for analyzing ciliary function in human small airway epithelial cells.
• To offer a protocol adaptable for different lung regions and species.

Main Methods:

• Detailed steps for experimental setup configuration.
• Methods for collecting quantitative CBF and MCT data.
• Procedures for data analysis and post-acquisition processing.

Main Results:

• The protocol enables precise measurement of CBF and MCT.
• Successful application demonstrated in mucociliary human small airway epithelial cells.
• Adaptability confirmed for other lung cell types and mouse tracheal cells.

Conclusions:

• This protocol offers a robust tool for studying lung ciliary function.
• It facilitates research into respiratory health and diseases linked to ciliary dysfunction.
• The method's adaptability enhances its utility across diverse research settings.
