Knockdown of either Tcf7 or Hcar2 in CD8+ T cells abolishes the promoting effect of βOHB on CD8+ T function. Our findings elucidate a metabolite-immune axis that directly regulates the functional state of tumor-infiltrating CD8⁺ T cells and provide experimental evidence linking ketone metabolism to anti-tumor immune regulation.
