Interferon-γ and cancer immunoediting
Over the last 12 yr, we have shown that interferony and lymphocytes collaborate to regulate tumor development in mice. Specifically, we found that the immune system not only prevents the growth of primary (carcinogen-induced and spontaneous) and transplanted tumors but also sculpts the immunogenicity of tumors that form. These observations led us to refine the old and controversial “cancer immuno-surveillance” hypothesis of Burnet and Thomas into one that we termed cancer immunoediting that better emphasizes the paradoxical host-protective and tumor-sculpting roles of immunity on developing tumors. Our current work focuses on defining the molecular mechanisms that underlie cancer immunoediting and exploring the implications of this process for cancer immunotherapy.
