Abstract
The present invention relates to methods of providing a targeted, amplified antitumor immune response using antibody-based fusion proteins. More specifically, the invention relates to the use of antibody-based fusion proteins comprising an immunoglobulin portion capable of binding to a tumor antigen linked to a biologically active lymphokine. The immunoglobulin portion targets the fusion protein to the site of the tumor cells and the lymphokine portion stimulates the proliferation of immune T cells at the site of the tumor cells, thereby amplifying the anti-tumor immune response. In preferred embodiments of the invention, the immunoglobulin portion of the fusion protein is derived from the L6 monoclonal antibody and/or the lymphokine is interleukin-2.
