Summary of research interest:

The main focus of our research is to understand the molecular and genetic mechanisms of arterial stiffness and possible pharmacological or life style interventions to prevent or reverse it. Arterial stiffness, a vascular condition characterized by gradual loss of large blood vessel elasticity, occurs naturally with aging or prematurely in obese individuals. This phenomenon has recently emerged in several clinical studies, including the Framingham Heart Study, as an independent risk factor for cardiovascular disease and it can lead to cardiovascular complications, such as hypertension, or deterioration of kidney and brain functions. We use innovative in vivo and in vitro approaches to measure arterial stiffness and blood pressure, and to dissect active and passive properties of blood vessels. Inflammation, increased production of oxidant species, changes in structural and biomechanical properties of blood vessels and genetic components are investigated as possible contributors to arterial stiffness. In addition, Dr. Seta’s lab investigates mechanisms of aortic dissection and aneurysm, deadly cardiovascular conditions affecting the aorta, for which, currently, there are no pharmacological treatments.
