Research Interests
Immune cells have direct and indirect interaction with other cells. The indirect interactions include the secretion of small protein ligands such as cytokines, chemokines, and growth factors for binding and activating receptors. However, the molecular details of the binding mechanisms are still largely unknown. We are interested in understanding how these protein ligands interact with different receptors. We subsequently want to translate this information to develop small molecules modulating the protein ligands in a receptor-specific manner with therapeutic effects against inflammatory diseases and cancer. We use a variety of techniques, including biochemical and biophysical methods such as X-ray crystallography and NMR, high-throughput screening, virtual docking, biosensor-based label-free cellular assay system, as well as animal models of human diseases.
