CD274 and neuroblastoma: Previous reports demonstrate that PD-L1 likewise increases in other neuroblastoma cells apart from SH-SY5Y by IFNγ [35], indicating that different human neuroblastoma cell lines are responsive to IFNs when it comes to PD-L1 rise; however, future studies are necessary to determine if the OEA- and PEA-mediated potentiation of IFNβ-induced PD-L1 levels is present in other neuroblastoma cell lines.
