Biography

Dr. Deeney’s research is designed to discern the nutrient-derived metabolic signals leading to glucose- and fatty acid (FA)-induced insulin exocytosis from the pancreatic ß-cell. FA acutely stimulates glucose-induced insulin secretion (GSIS) while chronic exposure to elevated FA and glucose can result in glucolipotoxicity (GLT) with basal hypersecretion and inhibition of GSIS. Despite the adverse effects of chronic exposure, FA is known to be required for normal exocytosis from the ß-cell. Deciphering the dual effects of FA on GSIS will lead to the possible development of therapies that would reduce the inhibitory effects while sparing the stimulatory effects of FA on the ß-cell. Studies in his laboratory are aimed at identifying the lipids or lipid classes involved in enhancing and suppressing GSIS and assessing their effects on lipid-modulated or modulating proteins.
