Dr. Jetton received his B.S. in Biology from University of North Carolina at Charlotte, NC in 1980.  He went on to receive a M.S. in Biology in 1983 from Western Carolina University, NC and his Ph.D. in Biology in 1990 from Vanderbilt University, TN.  Dr. Jetton did his postdoctoral work in Molecular Physiology/Biophysics at Vanderbilt School of Med from 1990 to 1993.

Dr. Jetton’s current effort is allocated towards research, teaching, and university-wide service.  He is a broadly trained biologist with a wide range of teaching and research interests in the life and medical sciences.  Although over the last 34 years his academic endeavors have largely been devoted to basic research, he has maintained a commitment to teaching, advising, and mentoring undergraduate and graduate students, pre-med/veterinary students, post-docs, medical students/fellows, and physician scientists.  In 1999, he was recruited to UVM’s Department of Medicine to strengthen the endocrinology research program in diabetes and pancreatic islet biology. He has garnered 3 NIH Research grants, 3 American Diabetes Association Research Grants, 2 Juvenile Diabetes Foundation Awards, 3 pharmaceutical company grants, 2 collaborative USDA awards, 2 Diabetes Action Foundation Research Awards, and several smaller grants.  He currently has authored or co-authored 63 peer-reviewed papers and has served as senior or corresponding author on 27 abstracts.  He also was instrumental in obtaining NIH-NCRR funding to procure 2 state-of-the-art research microscopes for UVM.  Dr. Jetton has served on numerous federal and private foundation research grant review panels as well as a big pharma R&D advisory panel.

Dr. Jetton’s early work at UVM identified essential mechanisms of how pancreatic b-cell mass increases in response to a range of physiological and pathophysiological insults.  He now studies how dietary factors and the brain control b-cell growth and maintain steady state mass.  Our recent work has bearing on the potential strategies to maintain b-cell mass and/or improve their health and curtail immune destruction in diabetic patients.  This has been learned from studies (1) identifying and characterizing a drug targetable b-cell receptor (a7nAChR) that improves ß-cell function and survival (with Dr. M. Gilbert) and (2) testing the effects of specific dairy-derived nutrients on metabolic health (with Dr. J. Kraft).  In a collaborative project with the USDA, Dr. Jetton is spearheading studies examining how environmental exposures lead to increased risk for metabolic diseases and how this might be mitigated through dietary or pharmacologic manipulation.
