摘要:

免疫治疗是一种新型抗肿瘤方法,免疫检查点抑制剂的应用大大提高了患者的生存获益,但是免疫治疗耐药问题影响治疗疗效。因此,探索肿瘤免疫治疗耐药机制及解决耐药问题至关重要。肿瘤微环境缺氧状态是免疫耐药的关键因素,缺氧通过多种作用机制抑制免疫细胞杀伤功能,促肿瘤细胞免疫逃逸;阻断缺氧相关通路可能成为克服免疫治疗耐药的突破点。通过总结缺氧状态诱导免疫治疗耐药的机制,有助于探讨缺氧诱导因子-1α(HIF-1α)相关蛋白靶向药在免疫治疗临床应用中的发展前景。

Abstract:

Immunotherapy is a new anti-tumor method. The application of immune checkpoint inhibitor greatly improves the survival benefit for patients, but the drug resistance of immunotherapy affects the efficacy. Therefore, it is very important to explore the mechanism of drug resistance and solve the problem of drug resis-tance in tumor immunotherapy. Hypoxia in tumor microenvironment is the key factor of immune drug resistance. Hypoxia can inhibit the immune cells function and lead to immune escape through various mechanisms. It can be the breakthrough for overcoming the immunotherapy drug resistance that blocking pathway of hypoxia to promote immune resistance. By reviewing the mechanism of immunotherapy drug resistance induced by hypoxia, it is helpful to explore the development prospect of hypoxia-inducible factor-1α (HIF-1α) related targeted drugs in clinical application for immunotherapy.
