IFNG and neoplasm: 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.
