CD8⁺ T cell abundance in the tumor microenvironment is critical for immunotherapy success. This study shows that the STING–TOX axis suppresses CD8⁺ T cell antitumor activity by inducing ferroptosis. STING–TOX-deficient CD8⁺ T cells enhance outcomes when combined with checkpoint blockade or chemotherapy.
