Haemodynamic stress-induced breaches of the arterial intima trigger inflammation and drive atherogenesis.

Summary of "Haemodynamic stress-induced breaches of the arterial intima trigger inflammation and drive atherogenesis."

Inflammatory mediators, including blood cells and their products, contribute critically to atherogenesis, but the igniting triggers of inflammation remain elusive. Atherosclerosis develops at sites of flow perturbation, where the enhanced haemodynamic stress could initiate the atherogenic inflammatory process due to the occurrence of mechanic injury. We investigated the role of haemodynamic stress-induced breaches, allowing the entry of blood cells in the arterial intima, in triggering inflammation-driven atherogenesis.

Medical and Biotech [MESH] Definitions

Thickening and loss of elasticity of the walls of medium and large muscular ARTERIES with lesions in the innermost layer of the artery (ARTERIAL INTIMA). This disease process of atherogenesis includes the retention of cholesterol-rich LIPOPROTEINS and their binding to PROTEOGLYCANS in the arterial intima, generation of proinflammatory molecules that recruit MACROPHAGES to the subendothelial space, formation of FOAM CELLS, and eventual calcification of the arterial wall. These arterial plaques (atheromas) contain CARBOHYDRATES; BLOOD; and CALCIUM.

Common occlusive arterial disease which is caused by ATHEROSCLEROSIS. It is characterized by lesions in the innermost layer (ARTERIAL INTIMA) of arteries including the AORTA and its branches to the extremities. Risk factors include smoking, HYPERLIPIDEMIA, and HYPERTENSION.

Inflammation of the inner endothelial lining (TUNICA INTIMA) of an artery.

Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries.

Fatty acid esters of cholesterol which constitute about two-thirds of the cholesterol in the plasma. The accumulation of cholesterol esters in the arterial intima is a characteristic feature of atherosclerosis.
