    Collapse Overview
    The focus of our laboratory rests with exploring the influence of metabolic stress on accelerated atherosclerosis cardiovascular disease. Specifically, our interest is in how a protein called apolipoprotein E controls hematopoiesis through microRNA regulation to suppress atherosclerosis beyond its ability to lower plasma lipid levels.

    A second interest of our laboratory explores how diabetic hyperglycemia contributes to differential microRNA biogenesis in mature immune cells and their progenitors. Specifically, we examine how this impacts on the release of these microRNAs into extracellular vesicles including exosomes to impact systemic and vascular inflammation and atherosclerosis.

    Our goal is to develop engineered exosomes with defined microRNA cargo as new nanobiological effectors to control inflammation and atherosclerosis.
