Atherosclerosis and Extracellular Matrix

[Glycation of extracellular matrix proteins and its role in atherosclerosis].

Glycation consists in formation of advanced glycation end-products (AGE) during non-enzymatic reaction between reducing sugars and proteins, lipids or nucleic acids. This review is focused mainly on glycation of collagen and its role in acceleration of vascular disease. Collagen is an extracellular matrix protein characterized by unique structure forming fibrils with great anti-tensile and anti...

Extracellular matrix synthesis in vascular disease: hypertension, and atherosclerosis

Extracellular matrix (ECM) within the vascular network provides both a structural and regulatory role. The ECM is a dynamic composite of multiple proteins that form structures connecting cells within the network. Blood vessels are distended by blood pressure and, therefore, require ECM components with elasticity yet with enough tensile strength to resist rupture. The ECM is involved in conducti...

Atherosclerosis and matrix dystrophy.

Atherosclerosis is characterized by inflammatory metabolic change with lipid accumulation in the artery. Atherosclerotic plaque occurs at discrete locations in the arterial system and involves the proliferation of smooth muscle cells (SMCs) together with imbalance of the extracellular matrix elements, elastic fiber in particular. The role of elastin in arterial development and disease was confi...

Leukotriene receptor antagonism and the prevention of extracellular matrix degradation during atherosclerosis and in-stent stenosis.

OBJECTIVE The lipid-derived inflammatory mediators leukotrienes (LTs) are produced during vascular injury. The aim of the present study was to determine the role of LT receptor signaling in the pathophysiology of in-stent stenosis. METHODS AND RESULTS New Zealand White rabbits were fed 0.3% cholesterol and subjected to angioplasty with balloon dilatation and stent implantation in the right ca...
