新兴研究表明,介导肿瘤微环境(TME)中细胞间通讯的细胞外囊泡(EV)在驱动癌症进展中发挥着关键作用。肿瘤来源的小 EV 或外泌体 (TEX) 富含免疫抑制蛋白或靶向受体细胞中抑制途径的 microRNA,有助于将 TME 重新编程为促癌环境。腺苷能途径是公认的肿瘤诱导免疫抑制的主要贡献者。 TEX 携带该途径的成分并利用 ATP 产生腺苷 (ADO)。 TEX 相关的 ADO 成为抑制 T 细胞对治疗反应的关键因素。在此,讨论了 TEX 中 ADO 通路作为癌症驱动的免疫细胞抑制和免疫治疗抵抗的高效机制的重要性。
Emerging studies suggest that extracellular vesicles (EVs) mediating intercellular communication in the tumor microenvironment (TME) play a key role in driving cancer progression. Tumor-derived small EVs or exosomes (TEX) enriched in immunosuppressive proteins or in microRNAs targeting suppressive pathways in recipient cells contribute to reprogramming the TME into a cancer-promoting milieu. The adenosinergic pathway is an acknowledged major contributor to tumor-induced immune suppression. TEX carry the components of this pathway and utilize ATP to produce adenosine (ADO). TEX-associated ADO emerges as a key factor in the suppression of T cell responses to therapy. Here, the significance of the ADO pathway in TEX is discussed as a highly effective mechanism of cancer-driven immune cell suppression and of resistance to immune therapies.
