We are studying the structure and function of the human Toll-like receptor family and their signalling pathways. These molecules are required for initial responses to invading bacterial pathogens and are implicated in the generation of human disease states such as rheumatoid arthritis and septic shock. Our aim is to elucidate the detailed molecular structure of these receptors and the other components of the signalling pathway by X-ray crystallography, modelling and NMR methods. This information will provide a basis for the development of novel therapeutic agents effective in inflammatory diseases like rheumatoid arthritis.
The work is supported by grants from the European Union Fifth Framework programme ('Human Toll like receptors in chronic and degenerative disease'), the BBSRC Macromolecular assemblies initiative (Steroechemical mechanisms of signalling and translocation across membranes'), and the MRS ('Structural studies of human Toll/interleukin 1 receptor ectodomains and their ligands').
