Changes of junctions of endothelial cells in coronary sclerosis: A review

Area of Science:

• Cardiovascular Science
• Vascular Biology
• Cell Biology

Background:

• Atherosclerosis is a primary driver of cardiovascular disease morbidity and mortality, with a rising global prevalence.
• Endothelial cell-cell junctions are essential for maintaining vascular integrity and function.
• Dysfunction of these junctions represents an initial step in the development of coronary events and coronary artery disease.

Purpose of the Study:

• To investigate the role of endothelial cell-cell junctions in the pathogenesis of atherosclerosis.
• To understand the mechanisms by which endothelial junction dysfunction contributes to cardiovascular disease.

Main Methods:

• Review of current literature on endothelial cell biology and atherosclerosis.
• Analysis of molecular pathways involved in endothelial cell-cell junction regulation.
• Examination of preclinical and clinical data linking junctional integrity to vascular health.

Main Results:

• Endothelial cell-cell junctions play a crucial role in preventing leukocyte transmigration and maintaining barrier function.
• Loss of junctional integrity in endothelial cells compromises vascular homeostasis.
• Specific molecular alterations in endothelial junctions are associated with early atherosclerotic lesion formation.

Conclusions:

• Endothelial cell-cell junction integrity is vital for vascular health and prevention of atherosclerosis.
• Targeting endothelial junction dysfunction presents a potential therapeutic strategy for cardiovascular disease.
• Further research into endothelial junction modulation may offer new avenues for treating and preventing coronary artery disease.
