NOTE: T cell reactivity towards the FR tumor antigen and allogeneic stimulator PBMCs was determined by assaying IFN-γ secretion (pg/mL) using ELISA following overnight incubation of Tcells with the targets listed. Plastic-coated anti-CD3 (OKT3) was used as an indicator of maximal T cell response. Transduced T cells from all patients were reactive with FR, and T cells from patients in cohort 2 were reactive with allogeneic PBMCs. Nontransduced Tcells did not respond against IGROV-1, except for patient 14 in whom 548 pg/mL IFN-γ was secreted (data not shown).
