Animation of Initiation of Atherosclerosis - Macrophage Activation 1

This animation shows a simplified version of the macrophage's role in the initiation of atherosclerosis. In an atherosclerotic-prone blood vessel, macrophages invade the subendothelial space. Oxidised Low-Density Lipoproteins (oxLDL) present within the vessel wall will bind to scavenger receptors on the macrophage's surface, such as CD36. This will activate the macrophage, and it will phagocytose the oxLDL. As this process continues, the macrophage increases in size and forms a Foam Cell, which is too large to pass between the endothelial cells back into the lumen. Therefore, the foam cells remain in the subendothelial space and are the main cells present within an atherosclerotic plaque. *** Done for Student Selected Component (SSC), University of Aberdeen. Year 2. 2011. Made in Adobe Photoshop CS2 and Adobe Imageready.

Coronary artery stents in Atherosclerosis

Atherosclerosis is the condition in which an artery wall thickens as the result of a build-up of fatty materials such as cholesterol.It most commonly becomes seriously symptomatic when interfering with the coronary circulation supplying the heart or cerebral circulation supplying the brain, and is considered the most important underlying cause of strokes, heart attacks, and most cardiovascular diseases, in general. A stent is a man-made 'tube' inserted into a natural passage/conduit in the body to prevent, or counteract, a disease-induced, localized flow constriction. Stents are used to counter narrowing of arteries due to plaque deposition and hardening.

Peripheral Vascular Disease (PVD)

Peripheral vascular disease (PVD) is due to atherosclerosis of arteries in the limbs. The level of arterial occlusion present is proportional to the symptoms. The pathogenesis and risk factors are the same as for coronary artery disease (CAD), and include: Hypertension Dyslipidaemia High LDL and low LDL levels Diabetes Obesity FH of arterial disease Smoking Age Male gender   Epidemiology
