Abstract Summary

Atherosclerotic diseases such as heart attack and stroke are the leading cause of death in the Western world. We investigate mechanisms that account for pathological changes in the vessel wall which are involved in the development of atherosclerosis. We focus on the role of the so-called angiotensin AT1 receptor, a gene that has a negative effect on the atherosclerotic process. We created mice that are prone to atherosclerosis development and lack this receptor and use this model and other techniques to investigate the relevance of AT1 receptor activation for the function of regenerating progenitor cells, the regeneration of the inner wall of the arteries after vascular injury and the development of atherosclerosis. Furthermore, we explore the relevance of this receptor for pathological changes involved in the development of diabetes mellitus and obesity. These studies will give new insights into the pathogenesis of atherosclerosis and will possibly enable new therapeutic strategies for the treatment of this disease.
