Control of atherosclerotic plaque vulnerability: insights from transgenic mice

Area of Science:

• Cardiovascular Biology
• Translational Medicine
• Genetics

Background:

• Atherosclerosis is a complex, progressive arterial disease involving lipid and cellular accumulation.
• Understanding the molecular mechanisms of atherosclerotic plaque progression is critical.
• Genetically-engineered mouse models offer valuable tools for studying this disease.

Purpose of the Study:

• To review the relevance, advantages, and disadvantages of genetically-engineered mice for investigating plaque vulnerability mechanisms.
• To highlight insights gained from these models for controlling plaque vulnerability.

Main Methods:

• Review of existing literature on genetically-engineered mouse models in atherosclerosis research.
• Analysis of how genetic manipulations in mice affect key aspects of plaque development and vulnerability.
• Comparison of features in mouse lesions to human vulnerable plaques.

Main Results:

• Genetically-engineered mice replicate key features of human vulnerable atherosclerotic lesions.
• Manipulations in apoptosis, lipid metabolism, inflammation, matrix remodeling, and thrombosis pathways are effectively studied in mice.
• These models provide insights into the control of plaque vulnerability.

Conclusions:

• Genetically-engineered mouse models are indispensable for dissecting the molecular underpinnings of atherosclerosis and plaque vulnerability.
• These models facilitate the identification of therapeutic targets for managing vulnerable atherosclerotic plaques.
• Further utilization of these models will advance strategies for controlling atherosclerosis progression.
