Summary
Mouse models lacking apolipoprotein E or LDLR are crucial for studying atherosclerosis. This review examines how genetic deficiencies combined with factors like inflammation and glucose metabolism influence disease progression.
Area of Science:
- Cardiovascular Science
- Genetics
- Metabolic Disease
Background:
- Atherosclerosis is a complex disease influenced by genetic and environmental factors.
- Targeted mouse models, especially those deficient in apolipoprotein E (apoE) or low-density lipoprotein receptor (LDLR), are vital for research.
- Understanding these models is key to deciphering atherogenesis.
Purpose of the Study:
- To review the impact of combining apoE or LDLR deficiencies with key atherogenic factors.
- To explore the influence of inflammation, glucose metabolism, blood pressure, and coagulation/fibrinolysis on atherosclerosis.
- To discuss the utility of mouse models for studying human genetic variations in atherogenesis.
Main Methods:
- Review of experimental data from mouse models of atherosclerosis.
- Focus on models with combined genetic deficiencies (apoE or LDLR) and environmental/metabolic factors.
- Analysis of studies investigating inflammatory processes, glucose metabolism, blood pressure, and coagulation.
Main Results:
- Combined genetic deficiencies and specific factors significantly alter atherosclerosis development and progression.
- Inflammation, dysregulated glucose metabolism, hypertension, and altered coagulation impact atherogenesis.
- Mouse models provide insights into the multifactorial nature of atherosclerosis.
Conclusions:
- Mouse models are indispensable tools for dissecting the complex mechanisms of atherosclerosis.
- Further refinement of mouse models is needed to better predict human disease outcomes.
- Integrating genetic and environmental factors in models enhances understanding of atherogenesis.
