Abstract: Immune checkpoint inhibitors(ICIs)mainly promote anti-tumor immunity by relieving tumor immune suppression.Interferon-γ(IFN-γ)plays an important role in increasing tumor antigen presentation,inducing immune cell infiltration,and directly inducing tumor cell apoptosis,becoming a key factor in improving the efficacy of immunotherapy.The abnormal signaling pathway of IFN-γ and its own effect on promoting tumor are the key mechanisms that trigger resistance to ICIs therapy.Immunotherapy,when combined with IFN-γ or IFN-γ inducers,can effectively restore the presentation ability of MHC-I,increase immune cell infiltration,and thus improve the efficacy of immunotherapy.In addition,domestic and foreign scholars have achieved certain therapeutic effects on clinical trials by normalizing the IFN-γ signaling pathway and combining ICIs with JAKi.This review mainly introduces the role of IFN-γ in the treatment of tumor ICIs,providing direction for potential treatment strategies to reverse ICIs resistance and further providing theoretical basis for clinical application.
