This book gives an overview on important mechanisms involved in atherosclerosis and thereby presents targets some of which are used and others which may be useful for therapy and prevention of atherosclerosis. Since atherosclerosis is a multifactorial disease the scientifc approach must be multidisciplinary. Accordingly, the authors of this book represent different areas of methodology ranging from basic, clinical and population research as well as different fields of expertise ranging from metabolism to immunology and inflammation biology and to vascular biology.
