Eugene Sprague, Ph.D.



Dr. Eugene Sprague's lab is interested in vascular biology with particular emphasis onendothelial biology. Their efforts are currently directed toward exploring the influence of specific flow environments on the endothelial cellular and molecular mechanisms mediating key elements related to atherogenesis and restenosis at sites of stent revascularization. 

They are especially interested in the influence of low shear, reversing flow patterns as an important co-initiating factor in early atherogenesis as well as micro-flow disturbances around stent struts that may contribute to stent restenosis. These studies involve examining gene expression and cell surface expression or secretion of these molecules as well as examining the signaling mechanisms involved in transducing the mechanical stimulus of flow into these specific cellular and molecular responses.
