[Progress in study on animal models of 
chronic obstructive pulmonary disease]

Area of Science:

• Pulmonary Medicine
• Animal Modeling
• Respiratory Diseases

Background:

• Chronic obstructive pulmonary disease (COPD) is a progressive and potentially fatal lung condition with increasing global prevalence.
• Current therapeutic strategies for COPD are limited, highlighting the need for improved understanding of its pathogenesis.
• Developing a well-recognized and reproducible animal model is essential for advancing COPD research.

Purpose of the Study:

• To review the current status and challenges in establishing animal models for COPD.
• To identify key considerations for the development of effective COPD animal models.
• To highlight the importance of updated parameters and species selection in COPD modeling.

Main Methods:

• Literature review of existing COPD animal models.
• Analysis of critical parameters for COPD model evaluation.
• Discussion of species selection criteria for COPD research.

Main Results:

• No universally accepted animal model for COPD currently exists.
• Key aspects of COPD animal model development, including species choice and evaluation metrics, are subject to ongoing refinement.
• The establishment of robust animal models remains a significant challenge in COPD research.

Conclusions:

• Further research and consensus are needed to establish a definitive animal model for COPD.
• Standardized methodologies are required for reliable COPD animal model creation and validation.
• Advancements in COPD animal modeling are critical for future therapeutic development.
