Levels of the indicated cytokines were determined by standard ELISAs after an overnight culture of T cells from the time of infusion with either CD19-positive target cells or CD19-negative target cells. NGFR-K562 cells were used as CD19-negative target cells for all cultures. CD19-K562 cells were used as CD19-positive targets for the cultures preceding the TNF ELISAs. NALM6 cells were used as the CD19-positive target cells for the cultures preceding the IFNγ and IL-2 ELISAs.
Results are from the second treatment of patient 1.
