Strategies to increase local T3 availability in liver

Prof. Dr. Josef Köhrle,  Dr. Eva K. Wirth

T3 is a key regulator of hepatic lipid metabolism. Hypothyroidism has been linked to non-alcoholic (obesity-/ diabetes-associated) hepatosteatosis and its sequelae. We aim to elevate local T3 concentrations by steering activities of T3-degrading deiodinase isozymes in hepatocytes by using selective deiodinase (DIO) isozyme inhibitors. Local T3 effects will be monitored by T3-sensitive reporter constructs expressed in THAI mouse-derived primary hepatocyte cultures and hiPSC-derived hepatocyte cell lines.
