IL7 and glioblastoma: To accomplish this, we transfected mouse glioblastoma lines GL261 and CT2A with GIFT‐7 plasmid allowing for endogenous production of the fusokine by the glioma cells (GL261GIFT‐7 vs GL261VC: GM‐CSF: 250 absorbance units (AU) vs. 5.69 AU p < 0.0001; GL261GIFT‐7 vs GL261VC: IL‐7: 1056.66 AU vs. 0 AU p < 0.0001) (Figure S1a).
