Project description
The aim of this project is to deliver new information on contribution of selected 2OGDDs to normal physiology and disease mechanisms, and to discover new treatment options for metabolic, neurological and other diseases exploiting modulation of the 2OGDDs. We focus on obesity and neurodegenerative diseases that are increasing rapidly, having limited treatment options and causing high burden to individuals and the society. The project uses molecular, biochemical and cellular methodologies, systemic studies in experimental animals using preclinical disease models and translation to human context.
