Apolipoprotein B-containing lipoproteins and atherosclerotic cardiovascular disease

Area of Science:

• Cardiovascular Science
• Lipid Metabolism
• Atherosclerosis Research

Background:

• Apolipoprotein B (apoB)-containing lipoproteins are established as major causal agents in atherosclerotic cardiovascular disease.
• Converging evidence highlights low-density lipoprotein (LDL) and related particles as central to atherosclerosis development.

Purpose of the Study:

• To review the critical role of atherogenic apoB-containing lipoproteins in cardiovascular disease.
• To discuss other contributing humoral and parietal factors in arterial degeneration.
• To briefly review foam cell biology and high-density lipoprotein (HDL) interactions, including cholesterol efflux.

Main Methods:

• Literature review of fundamental research on lipoprotein metabolism and atherosclerosis.
• Synthesis of evidence from multiple orthogonal lines of research.
• Review of cellular and molecular mechanisms involved in atherogenesis.

Main Results:

• Atherogenic apoB-lipoproteins are principal etiological agents in atherosclerosis.
• Arterial degeneration requires the interplay of lipoproteins with other humoral and parietal factors.
• Foam cell formation and HDL-mediated cholesterol efflux are integral to the disease process.

Conclusions:

• Atherogenic apoB-lipoproteins are indispensable in the pathogenesis of cardiovascular disease.
• Understanding these lipoproteins and associated factors is crucial for developing effective therapies.
• Further research into foam cell dynamics and HDL function can offer new therapeutic targets.
