The scientific focus of our laboratory is to study the interactions of viruses with the immune system, with translational emphases on cancer and infectious disease. There are two major projects ongoing: 1) investigating tumor virus immunity during carcinogenesis and lymphomagenesis; and 2) developing therapeutic human monoclonal antibodies using an in vitro technology invented in our lab (International Patent Application No. 08797131.3-1521 PCT/US2008/072124).
Epstein-Barr virus (EBV) and human papillomavirus (HPV) are common tumor viruses causing human cancers. Our lab looks at the interaction of these oncogenic viruses with a human endogenous retrovirus. We discovered that both EBV and HPV transactivate the endogenous retrovirus, which encodes a superantigen that strongly stimulates the immune system. The superantigen is expressed in EBV and HPV infected cancers, suggesting a possible etiological role. Superantigens cause localized inflammation, which might affect viral tumorigenesis and immune surveillance. Efforts are directed at controlling the superantigen stimulation for immunotherapy. We also study the role of EBV infection on B cell differentiation and immunoglobulin secretion, with regards to cancer and autoimmunity.
Human monoclonal antibodies are a class of drugs known as biologicals that have been used therapeutically in cancer, autoimmunity and infectious disease. Our lab has developed a novel method for creating fully human antibodies in vitro, using EBV to immortalize human B cells, which are then induced to differentiate into antibody producing cells. This creates reusable libraries of antibody producing cells, which can be screened for various antibodies of interest. We are developing monoclonal antibodies for use as cancer therapeutics, targeting tumor antigens (nucleolin) and angiogenic agents (placenta growth factor), and we are also developing antibodies for biodefense purposes, targeting lethal pathogens (H5N1 avian influenza virus) and toxins (Staphylococcal enterotoxins, ricin B).
