Mouse models for atherosclerosis and pharmaceutical modifiers.

Area of Science:

• Cardiovascular Research
• Translational Medicine
• Animal Models in Disease

Background:

• Atherosclerosis is a complex, multifactorial disease requiring accurate animal models for research.
• Effective treatments depend on models that mimic human metabolic and pathophysiological conditions.
• Mice are valuable, cost-effective models for atherosclerosis research and therapeutic development.

Purpose of the Study:

• To review and compare the responses of different mouse models to atherosclerosis risk factor treatments.
• To assess the utility of apolipoprotein E-deficient (ApoE-/-), LDL receptor-deficient (LDLr-/-), and ApoE*3Leiden (E3L) transgenic mice.
• To guide the selection of appropriate animal models for specific atherosclerosis research.

Main Methods:

• Literature review of studies investigating atherosclerosis mouse models.
• Analysis of model responses to compounds targeting hypercholesterolemia, hypertriglyceridemia, hypertension, and inflammation.
• Comparative assessment of ApoE-/-, LDLr-/-, and E3L mouse models.

Main Results:

• Different mouse models exhibit distinct responses to experimental manipulations and therapeutic compounds.
• ApoE-/- and LDLr-/- mice are widely used, while E3L mice are an emerging model.
• Model variability necessitates careful consideration for specific research questions.

Conclusions:

• The choice of animal model is critical and depends on the specific risk factor and therapeutic compounds being studied.
• Understanding model-specific responses is essential for the successful development of atherosclerosis treatments.
• Optimizing animal model selection enhances the validity and translational potential of atherosclerosis research.
