Ifn-Γ: A Cytokine At The Right Time, Is In The Right Place, J. Daniel Burke, Howard A. Young

Public Health Resources

Interferon gamma has long been studied as a critical mediator of tumor immunity. In recent years, the complexity of cellular interactions that take place in the tumor microenvironment has become better appreciated in the context of immunotherapy. While checkpoint inhibitors have dramatically improved remission rates in cancer treatment, IFN-Γ and related effectors continue to be identified as strong predictors of treatment success. In this review, we provide an overview of the multiple immunosuppressive barriers that IFN-Γ has to overcome to eliminate tumors, and potential avenues for modulating the immune response in favor of tumor rejection.
