 AB    The study of oncogenic viruses led to the discovery that transforming
       retroviruses contain oncogenes homologous with and/or derived from
       cellular proto-oncogenes. In humans malignant transformation is often
       the result of the activation of proto-oncogenes. Normal proto-oncogenes
       can be activated to transforming proto-oncogenes by a variety of
       mechanisms including point mutation, translocation and amplification.
       Development of successful strategies for the immunotherapy of human
       cancers is an area of intense investigation. Part of the problem in
       developing cancer-specific immunotherapy has been the lack of
       well-defined tumour antigens. Our laboratory has focused on the question
       of whether oncogenic proteins expressed by transforming proto-oncogenes
       can serve as targets for immune attack. Some patients with
       HER-2/Neu-positive breast cancer have an existent immune response to the
       HER-2/neu protein with no clinical signs of autoimmunity, supporting the
       idea that overexpressed oncogenic proteins can be targeted in therapy
       without fear of destructive autoimmunity. The identification of
       candidate cytotoxic T lymphocyte epitopes might allow the generation of
       tumour-specific cytotoxic T lymphocytes for use in therapy and identify
       potential epitopes for peptide vaccines.
