Research interests
The group led by Søren Moestrup investigates the role of macrophages receptors in inflammation such as the receptor CD163 that removes hemoglobin and haptoglobin from the circulation.
            
One focus is on characterizing the ligand binding of CD163, including identification of novel ligands. Another focus is on the development of techniques for specifically targeting small molecule drugs to macrophages, using monoclonal antibodies to make novel antibody-drug conjugates or targeted liposomes, both binding CD163. The macrophage plays a pivotal role in inflammation as the main producer of a range of pro-inflammatory cytokines, such as TNF and IL-1. By targeting glucocorticoids to the macrophages we can specifically inhibit the production of these pro-inflammatory cytokines, and we have shown that the efficacy of glucocorticoids is increased by a factor 50 through this specific targeting. The drug has been tested in inflammatory models in pigs, mice and rats. We are currently establishing other inflammatory models in order to characterize the role of the macrophage in other diseases and validate the specific targeting approach. In addition, a special subtype of the macrophage, the tumor associated macrophage, promotes the growth of tumors, and we are also working on targeting these cells. The work in the laboratory ranges from early receptor identification, recombinant expression and purification of proteins, over characterization of receptor binding, to in vitro and in vivo testing of drug candidates.
