Key result

Endothelial shift from relaxing to contracting factors may drive atherogenesis.

Why the study?

The mechanisms by which endothelial dysfunction contributes to atherosclerosis, including the balance between endothelium-derived relaxing and contracting factors, require elucidation.

Implication

Endothelial modulation remains a potential but unproven target in atherosclerosis; extends mechanistic insights without supporting clinical practice changes.

Key Points

Review the cellular pathways governing endothelium-dependent relaxation and contraction, and examine how their dysfunction contributes to the pathogenesis of atherosclerosis.
Evaluated experimental data from isolated animal and human vascular tissues, including models with regenerated or reperfused endothelium.
Assessed receptor-mediated and G-protein-dependent signaling pathways responsible for the production of relaxing and contracting factors.
Atherosclerotic and regenerated blood vessels exhibit a selective impairment of pertussis toxin-sensitive G-protein pathways mediating nitric oxide release, predisposing vessels to vasospasm and thrombosis.
Diseased blood vessels maintain or augment the synthesis of endothelium-derived contracting factors, including endothelin, thromboxane A2, and superoxide anions.
The progressive shift from dominant endothelium-dependent vasorelaxation toward enhanced vasoconstriction promotes vascular smooth muscle growth and lesion development.

Population

Atherosclerosis and endothelial dysfunction

Endothelial dysfunction, characterized by a shift from endothelium-derived relaxing factors to contracting factors, plays a crucial role in the pathogenesis of atherosclerosis.

Paul M. Vanhoutte (1997) conducted a review in Atherosclerosis and endothelial dysfunction. The switch from a normally predominant release of endothelium-derived relaxing factors to contracting factors may play a crucial role in the development of atherosclerosis.
