The tumor microenvironment is immunosuppressive. Here we preview two recent studies from Ma et al. (2021) in Cell Metabolism and Xu et al. (2021) in Immunity that describe a key role of T cell-expressed CD36 in enhancing lipid uptake and mediating lipid peroxidation that ultimately leads to CD8+ T cell dysfunction, ferroptosis, and reduced anti-tumor function.
肿瘤微环境具有免疫抑制性。在这里,我们先预览一下 Ma 等人(2021 年)在《细胞代谢》和 Xu 等人(2021 年)在《免疫》上发表的两项最新研究,这两项研究描述了 T 细胞表达的 CD36 在增强脂质摄取和介导脂质过氧化中的关键作用,最终导致 CD8+T 细胞功能障碍、铁死亡和抗肿瘤功能降低。
