New Research On Atherosclerosis

Atherosclerosis is a degenerative condition in which arteries build up deposits called plaques (atheromas) which consist of lipids (mainly cholesterol), connective tissue and smooth muscle cells originating from the arterial wall. Plaques develop quietly over a period of years and are unnoticeable until there is an interruption in the normal flow of blood. Plaques may partially or totally block the blood's flow through an artery. Two things that can happen where plaques occur are: bleeding (haemorrhage) into the plaque; and formation of a blood clot (thrombus) on the plaque's surface. Atherosclerosis affects large and medium-sized arteries. The type of artery and where the plaque develops varies with each person. Atherosclerosis research has witnessed startling progress in recent years, partially due to new drugs as well as to new breakthroughs in molecular medicine.

This monograph on recent progress in atherosclerosis research presents state-of-the art morphological investigations on the cells and their metabolism in the atherosclerotic plaque in situ. The spectrum of methods includes immunohistologic and immunoelectron microscopic investigations on the localization of apolipoproteins in the cells of the arterial intima, presenting new data on the lipoprotein metabolism in plaque. The collagen metabolism is analysed by in situ hybridization techniques for demonstrating the synthesis of different collagen types on the messenger RNA level. Concentrating on in situ investigations with sophisticated morpholocial methods, the widespread discussion on atherogenesis is focused on the arterial wall and its morphological alterations. As morphology remains the basis for understanding the pathogenesis of disease, the results presented here could be of interest not only to pathologists, but also to clinicians and researchers working in the field of biology of atherosclerosis.
