Cuproptosis Promotes Antitumour Immunity

In a recent study, Lei, Lu, Xu et al. identify cuproptosis as a form of immunogenic cell death that stimulates adaptive antitumour immunity. In turn, CD8⁺ T cell-derived IFNγ enhances tumour sensitivity to cuproptosis through STAT1–IRF1–FDX1 signalling, establishing a reciprocal immunometabolic circuit with important implications for cancer immunotherapy.
