Human CD36: Gene Regulation, Protein Function, and Its Role in Atherosclerosis Pathogenesis

Area of Science:

• Molecular Biology
• Cardiovascular Science
• Immunology

Background:

• CD36 functions as a scavenger receptor, critical for clearing long-chain fatty acids (LCFAs) and oxidized low-density lipoprotein (ox-LDL).
• The CD36 gene exhibits complex alternative splicing and promoter usage, leading to varied transcript expression across tissues.
• CD36 activity is implicated in inflammation, angiogenesis, phagocytosis, and energy homeostasis, influencing vascular and cardiovascular health.

Purpose of the Study:

• To review the multifaceted role of CD36 in cardiovascular disease (CAD) pathogenesis.
• To elucidate the relationship between CD36 receptor activity and atherosclerosis development.
• To highlight CD36 as a potential therapeutic target for atherosclerosis-related complications.

Main Methods:

• Literature review focusing on CD36 gene expression, function, and its role in atherosclerosis.
• Analysis of the molecular mechanisms regulating CD36.
• Examination of CD36's involvement in lipid metabolism and inflammatory pathways.

Main Results:

• CD36 is essential for removing ox-LDL, a key factor in atherosclerosis.
• Complex gene regulation of CD36 contributes to its diverse roles in different tissues.
• Despite rare mutations in Caucasians, CD36's role in ox-LDL uptake is significant in atherosclerosis development.

Conclusions:

• CD36 receptor activity is a critical determinant in the pathogenesis of atherosclerosis.
• Understanding CD36's function is vital for developing novel therapeutic strategies for CAD.
• Targeting CD36 may offer a promising approach to manage atherosclerosis and its complications.
