    Article Title: Tumor-secreted FGF21 acts as an immune suppressor by rewiring cholesterol metabolism of CD8 + T cells.
    Article Snippet: In brief Tumor-infiltrating T cells exhibit dysfunction.. Hu et al. report that tumorsecreted FGF21 augments cholesterol production by sustaining the hyperactivation of mTORC1 in activated CD8T cells, consequently inducing T cell exhaustion and impairing CD8T antitumor function.. FGF21 blockade improves anti-tumor immunity, highlighting FGF21 as a potential therapeutic target for cancer immunotherapy.
