摘要
免疫检查点抑制剂(Immune checkpoint inhibitors,ICIs)主要通过解除肿瘤免疫抑制作用促进抗肿瘤免疫.干扰素-γ(Interferon-γ,IFN-γ)在增加肿瘤抗原提呈、诱导免疫细胞浸润和直接促进肿瘤凋亡方面发挥了重要作用,成为提升免疫治疗疗效的关键因素.IFN-γ的信号通路异常及自身的促肿瘤作用是引发ICIs治疗耐药的关键机制.免疫治疗通过与IFN-γ或IFN-γ诱导剂联用,能够有效恢复MHC-I的呈递能力、增加免疫细胞浸润,进而提高免疫治疗效果.此外,国内外学者通过使IFN-γ信号通路正常化、将ICIs与JAKi联用等方法在临床试验中取得了一定疗效.本综述主要介绍了IFN-γ在肿瘤ICIs治疗中发挥的作用,为逆转ICIs耐药的潜在治疗策略提供方向,进一步为临床应用提供理论基础.
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 provi-ding theoretical basis for clinical application.
