Mechanisms of Immune Modulation by Radiation

Radiation is a known immune modulator that drives both local and systemic immunologic effects. There is increasing interest and investigation into harnessing the pro-immunogenic effects of radiation for patients with metastatic cancer to improve systemic disease control and clinical outcomes. Here,...

Description
Summary:Radiation is a known immune modulator that drives both local and systemic immunologic effects. There is increasing interest and investigation into harnessing the pro-immunogenic effects of radiation for patients with metastatic cancer to improve systemic disease control and clinical outcomes. Here, we review fundamental immunology concepts in the context of our current understanding of both the pro-immunogenic and the less well-appreciated immunosuppressive effects of radiation therapy. Our aim is to offer the radiation oncology community a lens into the progress the field has made understanding the complex interaction between tumor-directed irradiation and immune-mediated tumor control, thus promoting further discovery and translation of radio-immuno-oncology innovation.
