As we used cocultures of OAV infected GBM cells and HLA-A/B matched PBMCs (to mimic the situation in the tumor area) to determine the IFNγ release, we could not discriminate whether the IFNγ we measured originated from the OAV infected GBM cells or from the cocultured PBMCs or from both. This evidence concerns the gene IFNG and glioblastoma.
