BACKGROUND: CD8 T cells are critical for the oncogenesis and progression of the hepatocellular carcinoma (HCC) tumor microenvironment, receiving antigen signals from antigen-presenting cells and directly contributing to antitumor responses. SUMMARY: CD8 T cells mediate immunogenic cell death, facilitate immune signal transmission, and play a significant role in various treatments, including surgery, transarterial chemoembolization, and immunotherapy. Extensive research on the role of CD8 T cells within the HCC microenvironment has shown considerable progress. Immunometabolic targets on CD8 T cells have demonstrated potential in combination with immunotherapies for HCC; however, they have not yet reached the clinical trial stage. KEY MESSAGES: This review provides a comprehensive overview of recent research on immune and immunometabolic targets of CD8 T cells within the HCC microenvironment. By highlighting advances and potential mechanisms, this review aims to support the development of effective clinical strategies in this field.
背景:CD8 T细胞对于肝细胞癌(HCC)肿瘤微环境的肿瘤发生和进展至关重要,它从抗原呈递细胞接收抗原信号并直接促进抗肿瘤反应。 总结:CD8 T细胞介导免疫原性细胞死亡,促进免疫信号传递,并在包括手术、经动脉化疗栓塞和免疫治疗在内的各种治疗中发挥重要作用。对HCC微环境中CD8 T细胞作用的广泛研究已取得显著进展。CD8 T细胞上的免疫代谢靶点已显示出与HCC免疫疗法联合使用的潜力;然而,它们尚未进入临床试验阶段。 关键信息:本综述全面概述了HCC微环境中CD8 T细胞免疫和免疫代谢靶点的最新研究。通过强调进展和潜在机制,本综述旨在支持该领域有效临床策略的发展。
