Our laboratory focuses on the regulation of antigen specific T cell responses and studies approaches to modify these responses for immunotherapy. We have a particular interest in cancer immunology and our studies on basic immunologic mechanisms have led to the development and design of a number of cancer vaccines, some of which are currently being tested clinically. Specifically, the interests of the laboratory fall into four areas:
Immunologic Tolerance – one of the important revelations in the area of cancer immunology is that the major mechanism by which tumors grow unchecked by the immune system in their ability to induce tolerance among mature T cells specific for tumor antigens.
Antigen Presentation—one of the cancer vaccine approaches that are being actively tested clinically is vaccination with tumor cells transduced with the GM-CSF gene.
Definition of Immunodominant and Immunorelevant Tumor Antigens – Ultimately we wish to define the biological and biochemical rules that determine which antigens are dominant targets for immune responses.
Dissection of Immunologic Effector Pathways – Our studies on GM-CSF gene modified tumor vaccines have led to the identification of novel effector pathways in tumor immunity.
