Fruzsina K. Johnson, MD
Professor of Preclinical Sciences
Doctorate of Medicine, Semmelweis University, Budapest Hungary
Hungarian born, Dr. Johnson started Medical School at Semmelweis University (Budapest, Hungary) in 1991 and began her research carrear with their 2nd Department of Physiology. During her medical training, Dr. Johnson participated in a two year Research Associate Externship at New York Medical College's Department of Pharmacology. Following the completion of her MD, Dr. Johnson joined Tulane’s Department of Physiology as a Postdoctoral Fellow in 2000, rose to the rank of Instructor in 2002 and became an Assistant Professor in 2004. Dr. Johnson’s major research interests include cardiovascular function, microcirculation and vascular pathophysiology, mechanisms of hypertension, and biological roles for porphyrin and gaseous messengers. Her early work demonstrated the importance of endogenously-formed carbon monoxide as a messenger within the vasculature. In subsequent studies, Dr. Johnson has provided compelling evidence that endogenously-formed carbon monoxide not only promotes relaxation of vascular smooth muscle, but can promote vasoconstriction by interfering with the vasodilatory actions of the nitric oxide system. Her research has profound implications as it suggests that endogeously-formed carbon monoxide may contribute to endothelial dysfunction and promote vasospasticity in certain hypertensive models and pathological conditions.
Dr. Johnson is one of the five Junior Faculty Investigators on the major interdipartmental Tulane COBRE grant from the National Center for Research Resources (NIH). She is a former recipient of an American Heart Postdoctoral Fellowship awarded though the Regional American Heart-Southeast Affiliate, and has recieved one year of equipment/supplies support from Solvay Pharmaceuticals Hypertension Yearly Grants Award Program. Fruzsina Johnson is also a recipient of the Microcirculatory Society's distinguished August Krogh Award. In addition, she has received a Carolyn Tum Suden/Francis A. Hellebrant Professional Opportunity Award from the American Physiological Society and the Tulane's Dean of the School of Medicine Award at Tulane Research Day in 2000. Dr. Johnson is a member of the American Physiological Society, the Microcirculatory Society, the American Heart Association’s Council for High Blood Pressure Research, the American Diabetes Association and the Shock Society.
