In addition, we evaluated the infiltrated immune cells in these three ferroptosis subtypes and found that subtype B was significantly enriched in Tfh, NKT, NK, CD4+ T, and CD8+ T cells, compared with the other two subtypes, suggesting that the TIME in association with ferroptosis subtype B was enriched in tumor-suppressive immune cells, which can partially explain the reason that patients with subtype B have the best prognosis. This evidence concerns the gene CD4 and neoplasm.
