[The role of CD44 in pathogenesis of atherosclerosis]

Area of Science:

• Cardiovascular Biology
• Immunology
• Molecular Medicine

Background:

• Atherosclerosis is a leading cause of mortality with incompletely understood pathogenesis.
• Current understanding involves inflammatory cell recruitment, smooth muscle cell activation, and endothelial dysfunction.
• The CD44 molecule, a primary hyaluronan receptor, is increasingly implicated in these processes.

Purpose of the Study:

• To review the multifaceted roles of CD44 in the pathogenesis of atherosclerosis.
• To highlight CD44's involvement in key cellular events contributing to atherosclerotic plaque formation and progression.

Main Methods:

• Review of existing scientific literature and studies on CD44 function in atherosclerosis.
• Analysis of CD44's molecular mechanisms in endothelial cells, smooth muscle cells, and inflammatory cells.

Main Results:

• CD44 mediates T-lymphocyte and monocyte adhesion to the endothelium.
• It stimulates pro-inflammatory cytokine release from macrophages.
• CD44 contributes to smooth muscle cell dedifferentiation and atherosclerotic plaque destabilization.

Conclusions:

• CD44 is involved in multiple stages of atherosclerosis pathogenesis.
• Inhibiting CD44 function presents a potential therapeutic avenue for atherosclerosis.
• Further investigation is required to fully elucidate therapeutic implications.
