Bench to Bedside: Modelling Inflammatory Arthritis

Area of Science:

• Immunology
• Rheumatology
• Preclinical Research

Background:

• Inflammatory arthritides, like rheumatoid arthritis, are significant causes of disability.
• Pre-clinical murine models are vital for identifying and validating therapeutic targets and drug candidates.
• Lack of standardized scoring in animal models complicates result interpretation and comparison.

Purpose of the Study:

• To introduce a detailed and implementable arthritis scoring system for murine models.
• To enhance the capture of arthritis characteristics and disease progression monitoring.
• To address ethical considerations and the principles of animal use reduction in arthritis research.

Main Methods:

• Development and implementation of a comprehensive arthritis scoring system for experimental arthritis.
• Detailed description of the scoring system for increased breadth of captured characteristics.
• Inclusion of ethical and experimental design factors for animal research.

Main Results:

• The proposed scoring system increases the breadth of captured arthritis characteristics.
• It supports responsive and adaptive monitoring of disease progression in murine models.
• Provides a framework for improved consistency and comparability across studies.

Conclusions:

• Standardized scoring is essential for robust interpretation and comparison of results from murine arthritis models.
• The developed system facilitates more reliable preclinical evaluation of novel therapeutics.
• Emphasizes the importance of ethical considerations and the 3Rs (Replacement, Reduction, Refinement) in animal research.
