Dr. György M. Nagy graduated from the Medical University at Pécs, Hungary in 1974. He began working in the Semmelweis University in the Second Department of Anatomy, led by Professor Béla Halász. Dr. Nagy received his PhD degree in Neuroendocrinology in 1992 and his DSc (Doctor of Science) degree in 1995.
He worked in Birmingham, Alabama at the University of Alabama at Birmingham, as a research fellow from 1984 to 1987 in the laboratory of Jimmy D Neill. He also spent two years (between 1989 till 1991) as a visiting professor in Charleston, South Carolina at the Medical University of South Carolina, in the laboratory of Steve L. Frawley and more than a year (between1997-1998) at Florida State University, Tallahassee, FL, in Marc E. Freeman’s laboratory.
Dr. Nagy’s main research fields are Neuroscience, Neuroendocrinology and Endocrinology. His main interests are: Cellular and molecular aspects of the regulation of pituitary function; Hypothalamic regulation of pituitary prolactin (PRL), ?-melanocyte-stimulating hormone (MSH) and adrenocorticotrope hormone (ACTH) secretion; Molecular recognition between different ligands and their receptors; Cellular and molecular aspects of tonic dopaminerg regulation and signaling through D2 dopamine receptors, the role of the phosphorylation/dephosphorylation processes in the second messenger cascade; the role of the peripheral sympathetic system in the regulation of pituitary function; Role of hypothalamo-pituitary releasing-inhibiting factors in immune regulation;
As a teacher, Dr. Nagy has taught Gross Anatomy, Neuroscience, Histology, Embryology, Endocrinology and Neuroendocrinology. He has had more than 15 students working in his laboratory and who have received their PhD degree under his supervision and mentorship.
A review article (Marc E. Freeman, Béla Kanyicska, Anna Léránt, György Nagy: Prolactin: Structure, Function, and Regulation of Secretion) published in Physiological Reviews (80: 1523-163, 2000), the number one ranked physiological journal, has been “the most frequently read article” between September, 2004 and September, 2008.
