Abstract:
Animal models have significantly advanced our understanding of the mechanisms of atherosclerosis formation and the evaluation of therapeutic options. The current focus of research is on preventive strategies and includes pharmacologic and biologic interventions directed primarily against smooth-muscle cell proliferation, endovascular devices for recanalization and/or drug delivery, and an integrated approach using both devices and pharmacobiologic agents. The experience over many decades with animal models in vascular research has established that a single, ideal, naturally available model for atherosclerosis does not exist. The spectrum ranges from large animals such as pigs to small animal experiments with genetically modified rodents such as the ApoE-/- mouse with correspondingly differently pronounced changes in their lipid and lipoprotein levels. The development of transgenic variants of currently available models, e.g., an ApoE-deficient rabbit line, has widened our options. Nevertheless, an appreciation of the individual features of natural or stimulated disease in each species is of importance for the proper design and execution of relevant experiments.
Insights
Animal models are crucial for studying atherosclerosis and its treatments. Researchers use diverse models, from pigs to genetically modified mice, to understand disease mechanisms and develop preventive strategies.
Area of Science:
- Cardiovascular Research
- Translational Medicine
- Animal Models in Disease Research
Background:
- Animal models are indispensable for elucidating atherosclerosis pathogenesis.
- Research increasingly focuses on preventive strategies, including pharmacologic, biologic, and device-based interventions.
- Decades of vascular research confirm no single ideal animal model for atherosclerosis exists.
Purpose of the Study:
- To review the utility and diversity of animal models in atherosclerosis research.
- To highlight the importance of selecting appropriate models for experimental design.
- To discuss current research trends in atherosclerosis prevention.
Main Methods:
- Review of established and emerging animal models for atherosclerosis.
- Comparison of large animal (e.g., pigs) and small animal (e.g., genetically modified rodents like ApoE-/- mice) models.
- Consideration of transgenic variants (e.g., ApoE-deficient rabbits) and their specific lipid profiles.
Main Results:
- A wide spectrum of animal models is available, each with distinct advantages and limitations.
- Genetically modified rodents and transgenic variants offer tailored approaches to studying specific disease aspects.
- Different models exhibit varying degrees of lipid and lipoprotein alterations.
Conclusions:
- The choice of animal model significantly impacts the relevance and success of atherosclerosis research.
- Understanding the unique features of each species' disease model is critical for experimental validity.
- Integrated approaches combining pharmacobiologic agents and endovascular devices are a key research focus.
