Interferon, type I interferon and IFN‐γ (IFNG) promote SAR and CD8 + T‐cell activity and T‐cell cross‐priming.24 Multiple studies have shown that type I interferons (IFNs) play an important role in tumour control by promoting the reactivation (reactivation) of T cells by dendritic cells (DCs).25 Our study found that high expression of WTAP can reduce T‐cell infiltration and inhibit tumour immunity, which may be supported by the above studies. The gene discussed is CD8A; the disease is neoplasm.
