Function of the Erythropoietin Receptor in anti-inflammatory Signalling:

While it has been known for several decades that the EpoR plays an important role in erythropoiesis, it is now becoming clear that this receptor is also involved in inflammatory processes. Epo has been found to down-regulate the production of pro-inflammatory cytokines, but the mechanistic details of its signalling pathways in immune cells have not been fully discovered yet. We aim to unravel these pathways on a molecular level and to determine its significance in inflammatory signalling.
