Nutrition and endothelial cell integrity: implications in atherosclerosis.
Loss of functional integrity of the vascular endothelium may be one of the initiating events in the etiology of atherosclerosis. Endothelial cells interact with blood components and the abluminal tissues, thus playing an active role in many aspects of vascular functions, such as permeability and vessel tone regulation. Endothelial cells constantly are exposed to nutrients which can modulate enzymes, receptors, transport molecules and various vasoactive mediators, resulting in significant functional changes of the endothelium and the underlying tissues. Nutrition may play an important role in the atherosclerotic disease process. There is evidence that certain vitamins and minerals prevent some metabolic and physiological perturbations of the vascular endothelium. This review focuses on selected lipids which cause endothelial cell injury or dysfunction and on nutrients which may exhibit antiatherogenic properties by being able to function as antioxidants or membrane stabilizers.
