Generation of T cells modified to express GMR CAR with piggyBac transposons. a A CAR targeting GM-CSF receptor (GMR CAR) was constructed by replacing the anti-CD19 scFv portion of a piggyBac transposon plasmid encoding CD19 CAR (pIRII- CAR.CD19) with full-length GM-CSF. b Surface expression of GMR CAR in transgenic T cells expanded by stimulation with anti-CD3/CD28 mAbs
