    Dr. Yang’s interests are antibody engineering, vaccine development, microbial pathogenesis, and molecular immunology.


    Research in Dr. Yang’s laboratory has focused on development of meningococcal vaccine. Monoclonal antibodies reactive to a broad spectrum of meningococcal cells have been obtained. Using immuno-proteomic and recombinant DNA approaches, the target antigen for one of the clones was identified to be a novel lipoprotein. This protein, designated Ag473, with no homologues of known function in the database is present in all tested N. meningitidis strains and its vaccine potential has been demonstrated in mouse model. Experiments are engaging to unravel the biological function of Ag473 and its expression pattern during infection because such information will provide important insight into the availability of this antigen as a vaccine antigen in vivo and comprehend our understanding of meningococcal pathogenesis. In the meantime, she will continue to identify and characterize the target antigens for the remaining antibodies which may lead to the discovery of previously unidentified vaccine candidates.
