High-density lipoproteins in high resolution: Will proteomics solve the paradox for cardiovascular risk?

Area of Science:

• Cardiovascular Science
• Biochemistry
• Analytical Chemistry

Background:

• Lipid abnormalities are a major risk factor for myocardial infarction, contributing to over 60% of attributable risk.
• The inverse relationship between high-density lipoprotein (HDL) cholesterol and cardiovascular risk has not yielded effective therapies.
• A deeper understanding of diverse HDL particle functions is needed for clinical applications.

Purpose of the Study:

• To explore the potential of high-resolution lipoproteomics for studying HDL particle kinetics.
• To discuss the development of an informatics platform to enhance throughput in lipoproteomic analysis.
