In this patient, vaccinations using autologous glioma as the antigen source induced a specific IFN-γ response against EphA2883–891 that was sustained for at least 6 weeks post-vaccination (Figure 2), although a specific response against IL-13Rα2345–353or autologous bulk glioma cells was not detectable in the same assays. This evidence concerns the gene IFNG and glioma.
