Insights
Atherosclerosis, a leading global killer, involves complex pathology and pathogenesis influenced by genetics and environment. New models and therapies are needed for patients unresponsive to statins.
Area of Science:
- Cardiovascular Science
- Pathology
- Molecular Biology
Background:
- Atherosclerosis is a major cause of death globally, stemming from genetic and environmental factors.
- Known risk factors include hypercholesterolemia, hypertension, diabetes, and smoking, contributing to vascular chronic inflammation.
- While statins are effective, many patients require novel treatments due to incomplete response.
Purpose of the Study:
- To review the pathology and pathogenesis of atherosclerosis.
- To discuss current understanding and identify unanswered questions in atherosclerosis research.
- To highlight the need for new animal models and therapeutic strategies.
Main Methods:
- Review of existing literature on atherosclerosis pathology and pathogenesis.
- Analysis of molecular mechanisms investigated through genetically modified animal models.
- Evaluation of the efficacy of current treatments like statins.
Main Results:
- Atherosclerosis develops over decades, involving chronic inflammation and interactions between risk factors and arterial cells.
- Genetically modified animals have advanced understanding of molecular mechanisms.
- Statins represent the most effective current treatment for prevention and management.
Conclusions:
- Despite progress, the complete pathogenesis of atherosclerosis remains incompletely understood.
- There is a critical need for innovative therapeutic approaches for statin-resistant patients.
- Development of new animal models is essential for further research into atherosclerosis.
Abstract:
Atherosclerotic disease, such as myocardial infarction and stroke, is the number one killer worldwide. Atherosclerosis is considered to be caused by multiple factors, including genetic and environmental factors. In humans, it takes several decades until the clinical complications develop. There are many known risk factors for atherosclerosis, including hypercholesterolemia, hypertension, diabetes and smoking, which are involved in the pathogenesis of atherosclerosis; however, it is generally believed that atherosclerosis is vascular chronic inflammation initiated by interactions of these risk factors and arterial wall cells. In the past 30 years, the molecular mechanisms underlying the pathogenesis of atherosclerosis have been investigated extensively using genetically modified animals, and lipid-reducing drugs, such as statins, have been demonstrated as the most effective for the prevention and treatment of atherosclerosis. However, despite this progress, questions regarding the pathogenesis of atherosclerosis remain and there is a need to develop new animal models and novel therapeutics to treat patients who cannot be effectively treated by statins. In this review, we will focus on two topics of atherosclerosis, "pathology" and "pathogenesis," and discuss unanswered questions.
