Advancing Myocarditis Research: Evaluating Animal Models for Enhanced Pathophysiological Insights.

Area of Science:

• Cardiology
• Immunology
• Translational Medicine

Background:

• Myocarditis research relies heavily on animal models to elucidate disease pathophysiology.
• Existing models, including viral and autoimmune, present unique strengths and limitations.

Purpose of the Study:

• To critically evaluate current animal models for myocarditis research.
• To assess their utility in understanding disease mechanisms and guiding therapeutic interventions.
• To propose optimizations for enhanced relevance and reliability in myocarditis studies.

Main Methods:

• Review of recent literature on animal models used in myocarditis research.
• Analysis of viral, autoimmune, and vaccine-associated myocarditis models.
• Evaluation of model strengths, weaknesses, and clinical applicability.

Main Results:

• Viral models (e.g., Coxsackievirus) offer high success rates but limited human relevance.
• Autoimmune models, including humanized mice, better mimic immune responses but face accuracy challenges.
• Vaccine-associated myocarditis models are emerging but require further validation.

Conclusions:

• Current animal models for myocarditis research have distinct limitations in accurately reflecting human disease.
• Optimizing existing models and developing new ones are essential for improving our understanding and treatment of myocarditis.
• Future research should focus on refining models for better simulation of human conditions and clinical applicability.
