As immunosuppressive molecules (e.g., PD‐L1, IDO1, and IL‐18BP) that can be induced by interferon‐gamma (IFN‐γ) are generally important to facilitate immune evasion by tumor cells,[25] we wondered whether the expression of these immunosuppressive molecules in NPC cells is affected by CBX1. The gene discussed is CBX1; the disease is neoplasm.
