This research identifies a reciprocal relationship between cuproptosis, a copper-induced form of cell death, and antitumor immunity. The study demonstrates that cuproptotic tumor cells act as immunogenic cell death, releasing signals that activate dendritic cells and prime CD8+ T cells. In a feedback loop, these activated T cells release interferon-gamma (IFN-γ), which triggers the STAT1-IRF1 signaling pathway to increase FDX1 expression, making tumor cells even more vulnerable to copper-induced death. By leveraging this "crosstalk," the authors show that combining cuproptosis inducers with…
