Blood vessel alteration plays a significant role in arterial hypertension complications. Scientists in this research unit focus on the molecular function of smooth muscle and endothelial cells in the vessel walls of patients suffering from hypertension and in experimental animals. They are particularly interested in the changes that occur in small blood vessels, which play a crucial role in blood circulation, and their reaction under antihypertensive treatment. These studies will lead to the development of new therapeutic approaches in preventing arterial hypertension complications.
