Research Interests
Recent research in the laboratory involved the production of recombinant polyclonal antibodies for immunotherapy of cancer and infectious diseases. The current focus is to develop immunotherapies and elucidate the mechanisms of protective immunity against inhalational tularemia, an acute lethal infectious disease. Tularemia is caused by the gram-negative intracellular bacterium Francisella tularensis, which has been classified as a Category A Select Agent – a likely bioweapon. The high virulence of F. tularensis and the threat of engineered antibiotic resistant variants warrant the development of new therapies to combat this disease. We are developing a recombinant polyclonal antibody for post-exposure treatment of tularemia by selecting candidate monoclonal antibodies and converting them into mouse IgG2a and IgA, and into human IgG1. The efficacy of the antibodies, alone and in combinations, are tested in an inhalational mouse model of tularemia and/or in vitro human blood infection assays, and the immune components required for antibody efficacy are determined using immunoassays for cytokines and cell subsets as well as immunodeficient mouse strains. In addition, the target antigens of these antibodies are determined by proteome microarray analysis and the potential roles of selected antigens in bacterial pathogenesis are investigated.
