Contact Dr. Andrea Szuchman-Sapir

The research in our laboratory focuses on the elucidation of signal transduction mechanisms in the vessel wall, in particular in the endothelium, and on the generation of specific PUFA- derived metabolites that are potential endothelium–derived hyperpolarizing factors (EDHFs). Current projects aimed to elucidate the role of cytochrome P450-derived lipid mediators in vascular homeostasis and dilation that affects blood pressure. In addition, the role of paraoxonase 1 in the endothelium signaling cascades that affect endothelium-dependent relaxation is been investigated
