Animal models in chronic obstructive pulmonary disease-an overview

Area of Science:

• Pulmonology
• Pathophysiology
• Experimental Medicine

Background:

• Chronic obstructive pulmonary disease (COPD) involves progressive airway obstruction due to respiratory inflammation from harmful inhaled substances.
• The exact causes and mechanisms of COPD remain debated among experts.
• Existing knowledge gaps necessitate robust experimental models to study COPD's progression.

Purpose of the Study:

• To review and present key experimental models of COPD, with a specific focus on emphysema.
• To detail the characteristics, advantages, and limitations of each model.
• To assess the utility of these models in advancing understanding of COPD pathophysiology and evaluating novel therapeutic strategies.

Main Methods:

• Literature review of established and emerging experimental models for COPD and emphysema.
• Comparative analysis of different models based on their ability to replicate key disease features.
• Evaluation of model applicability for studying disease mechanisms and drug efficacy.

Main Results:

• Several experimental models exist for inducing emphysema-like changes and airway obstruction.
• Each model offers unique insights but also possesses specific limitations regarding disease mimicry.
• Models vary in their suitability for investigating specific pathophysiological aspects or testing targeted therapies.

Conclusions:

• Experimental models are crucial for dissecting COPD pathophysiology and developing effective treatments.
• Careful selection of appropriate models is essential for reliable research outcomes.
• Further refinement and validation of existing models are needed to fully address COPD research questions.
