Abstract

We have established that chaperonins (cpns) are potent stimulators of myeloid cells able to induce osterclast formation and activation, monocyte cytokine synthesis and dendritic cell activation. We propose the hypothesis that the ability of chaperonins to activate myeloid cells is due to these cells possessing a cell surface receptor(s) for this class of protein. We further hypothesise that the chaperonin receptor or receptors are pattern-recognition receptors and are part of the innate immune response to recognise bacteria. In preliminary studies we have used flow cytometry and plasmon resonance to establish that human monocytes bind cpn 60 with high affinity and using immunoadsorption and western blotting have identified a receptor, or part of a receptor, with a molecular mass of 60kDa. The aims of this application are to characterise this receptor biochemically and, depending on its nature, to clone it using either expression cloning or conventional cDNA cloning.
