Cholesterol trafficking, lysosomal function, and atherosclerosis

Area of Science:

• Cardiovascular Science
• Cell Biology
• Molecular Medicine

Background:

• Atherosclerosis remains a leading global cause of mortality.
• Cholesterol accumulation in vascular walls is an early pathogenic event.
• Dysregulated cholesterol transport contributes to atherosclerotic lesion development.

Purpose of the Study:

• To review recent advances in understanding vesicular cholesterol transport in atherosclerosis.
• To explore the relationship between cholesterol trafficking and disease progression.
• To highlight the therapeutic potential of targeting cholesterol transport mechanisms.

Main Methods:

• Review of current scientific literature on cholesterol transport and atherosclerosis.
• Analysis of cellular processes involved in intracellular cholesterol trafficking.
• Examination of the role of vesicular transport in foam cell formation.

Main Results:

• Abnormalities in vesicular cholesterol transport and lysosomal function lead to intracellular cholesterol accumulation.
• Foam cell formation, a hallmark of early atherosclerosis, is promoted by dysregulated cholesterol buildup.
• Cellular processes like endocytosis, exocytosis, intracellular trafficking, and autophagy are critical in foam cell development and plaque stability.

Conclusions:

• Vesicular cholesterol transport is intricately linked to the pathogenesis of atherosclerosis.
• Targeting mechanisms of vesicular cholesterol transport offers potential therapeutic strategies for cardiovascular disease.
• Further research into these pathways is crucial for developing effective prevention and treatment methods.
