Methods for Detecting Cough and Airway Inflammation in Mice

Area of Science:

• Pulmonology
• Animal Models
• Biomedical Research

Background:

• Chronic cough affects millions, causing significant socioeconomic burden and reduced quality of life.
• Animal models are crucial for understanding complex cough pathophysiology.
• Assessing cough sensitivity and airway inflammation is key to unraveling chronic cough mechanisms.

Purpose of the Study:

• To describe reproducible methods for measuring cough and airway inflammation in mice.
• To provide normative procedures for sample collection and analysis in cough research.
• To establish valuable tools for studying the pathophysiology of chronic cough.

Main Methods:

• Utilizing a noninvasive, real-time whole-body plethysmography (WBP) system for cough measurement.
• Implementing standardized procedures for harvesting mouse tissues (blood, lung, spleen, trachea).
• Assessing airway inflammation via HE staining, BALF analysis (protein, uric acid, LDH), and cell counts.

Main Results:

• The described methods for cough measurement and airway inflammation assessment are reproducible.
• These techniques provide quantitative data crucial for cough research.
• The study establishes a framework for standardized investigation of cough pathophysiology in animal models.

Conclusions:

• The described whole-body plethysmography and BALF analysis methods are valuable and reproducible tools.
• These techniques facilitate the study of chronic cough mechanisms and potential therapeutic targets.
• Standardized methodologies are essential for advancing our understanding and treatment of chronic cough.
