Area of Interest

1)Analysis of immune response to tumor associated antigens (TAAs) (ErbB receptors, AFP, CEA, PSA) in cancer patients.
2)Cancer immunotherapy: anti-cancer vaccines and murine and recombinant Mabs development
3)Expression of TAAs in tumors and normal tissues
4)Production and characterization of monoclonal antibodies to viral proteins
