Cholesterol is essential for the ability of cytotoxic T cells to eliminate cancer cells. In this issue of Cancer Cell, Yan et al. reveal how intra-tumoral cholesterol deficiency contributes to T cell exhaustion by inhibiting mTORC1 signaling. Moreover, they demonstrate that increasing cholesterol levels in chimeric antigen receptor (CAR)-T cells by blocking liver X receptor (LXR) leads to improved anti-tumor function.
胆固醇对于细胞毒性 T 细胞消除癌细胞的能力至关重要。在本期《癌细胞》杂志中，Yan 等人揭示了肿瘤内胆固醇缺乏如何通过抑制 mTORC1 信号通路导致 T 细胞耗竭。此外，他们还证明通过阻断肝 X 受体（LXR）来增加嵌合抗原受体（CAR）-T 细胞中的胆固醇水平可提高抗肿瘤功能。
