Bio

Dr. Csanyi earned his MPharm from the University of Szeged, Hungary in 2003 and followed this with a Ph.D. from the same institution in 2008. As a recipient of the Jozef Dietl Academic Scholarship and Queen Jadwiga Fund, he also studied at the Jagiellonian University Medical College, Krakow, Poland. In the summer of 2008, Dr. Csanyi moved to the University of Pittsburgh to seek postdoctoral training in the laboratory of Dr. Patrick J. Pagano. He completed a Great Rivers Affiliate Postdoctoral Fellowship funded by the American Heart Association in 2012. Dr. Csanyi was recently awarded the NIH Pathway to Independence Award (K99/R00).

Research Interests

Dr. Csanyi's research is directed toward a better understanding of the role of distinct vascular isoforms of NADPH oxidase (Nox1, Nox2, Nox4, and Nox5) and increased reactive oxygen species (ROS) production in the initiation and progression of vascular disease. During the course of his postdoctoral training, Dr. Csanyi has been intrigued by how the matricellular protein thrombospondin-1 (TSP1) regulates nitric oxide (NO) signaling in vascular disease. Dr. Csanyi has recently demonstrated that TSP1 is a rapid and robust activator of Nox1 in vascular cells and an important regulator of NO bioavailability. Since these original findings, Dr. Csanyi has developed an independent pathway that merges the two distinct fields of NADPH oxidase- and TSP1-signaling in vascular inflammatory diseases. A major focus of Dr. Csanyi’s current research is how TSP1 acts as a proximate promoter of macrophage and vascular parenchymal Nox and its role in the development of vascular disorders. His short-term goal is to develop this project into a unique research program expanding on this seminal discovery with high impact contributions to our mechanistic understanding of the factors controlling this novel pathway. Longer term, a broader vision for his work is the interrogation of the myriad ways matricellular proteins could affect phenotypic changes in macrophages, T cells, and vascular parenchymal cells, leading to vascular disease.
