肿瘤可以通过抑制肿瘤微环境(TME)中免疫细胞的活性来躲避免疫系统,其中细胞毒性 CD8+ T 细胞是免疫抑制的一个关键靶点。细胞新陈代谢》(Cell Metabolism)杂志上的一项研究发现了成纤维细胞生长因子21(FGF21)通过抑制CD8+ T细胞活性促进肿瘤生长的机制。与用对照培养基处理的 T 细胞相比,用中药处理的 T 细胞产生的 IFNγ 和颗粒酶 B 等分子大大减少。这一发现表明,T细胞的功能受到了肿瘤分泌因子的抑制。通过蛋白质组分析,研究人员发现,与对照培养基相比,FGF21是中药中持续上调的因子。与来自同一人的健康组织样本相比,来自结肠癌患者的肿瘤样本同样显示出 FGF21 的表达增加。
