缺氧不仅是实体瘤异质性的一个重要因素,也是微环境中的一个重要应激源,可驱动肿瘤适应性以逃避免疫监视。在此,我们讨论了微环境中缺氧对肿瘤细胞免疫抵抗和免疫抑制的潜在作用。我们概述了最近发现的缺氧驱动的适应性机制,通过扭曲重要的免疫检查点分子(例如,分化簇47、程序性死亡配体1和人白细胞抗原G)、改变的代谢和代谢物以及pH调节。重要的是,缺氧应激相关途径的抑制可以共同增强T细胞介导的肿瘤细胞杀伤。此外,我们讨论了如何操纵缺氧应激可能会带来一个有前途的新的战略,为组合治疗干预,以加强实体瘤的免疫治疗。
Hypoxia is not only a prominent contributor to the heterogeneity of solid tumors but also a crucial stressor in the microenvironment to drive adaptations for tumors to evade immunosurveillance. Herein, we discuss the potential role of hypoxia within the microenvironment contributing to immune resistance and immune suppression of tumor cells. We outline recent discoveries of hypoxia-driven adaptive mechanisms that diminish immune cell response via skewing the expression of important immune checkpoint molecules (e.g., cluster of differentiation 47, programmed death ligand 1, and human leukocyte antigen G), altered metabolism and metabolites, and pH regulation. Importantly, inhibition of hypoxic stress-relevant pathways can collectively enhance T-cell-mediated tumor cell killing. Furthermore, we discuss how manipulation of hypoxia stress may pose a promising new strategy for a combinational therapeutic intervention to enhance immunotherapy of solid tumors.
