Vascular Biology and Therapeutics Program

Vascular Biology and Therapeutics Program

The Vascular Biology and Therapeutics Program focuses on the biology of the vessel wall and in vivo/in vitro cell signaling of vascular smooth muscle cells. The emphasis of the program is to understand the responses of the vessel wall to injury, flow and atherogenic environments. Using in vitro and in vivo models of flow disturbance, arterial injury and vein grafting, the program provides a suitable environment for translational research in key areas of vascular biology. A better understanding of the cell biology of the vessel wall should lead to improved patency rates after intervention or bypass. The program provides its researchers with the most modern techniques in molecular and cell biology and systems biology. The program integrates these disciplines with physiological, pharmacological, pathological and therapeutic approaches to address questions in clinically relevant questions in vessel wall biology.

The three current areas of research interest are:

  1. biology and role of proteases in vascular smooth muscle cells
  2. the signal biology of phospholipids in vascular smooth muscle cells
  3. the signal biology of diabetes and metabolic syndrome in the vasculature

Current Funding
