CD8+ T cells have been shown to induce ferroptosis in tumor cells, while natural killer (NK) cells and cytotoxic T lymphocytes inhibit tumor cells through pyroptosis.[45, 46, 47] We utilized CIBERSORT to determine the proportions of various tumor-infiltrating immune cells in B-cell NHL, aiming to elucidate the potential immune landscape of cuproptosis in B-cell NHL. The gene discussed is CD8A; the disease is B-cell non-Hodgkin lymphoma.
