IFN-γ production by Kb-CD28-ζ and Kb-CD28[L→G]-ζ RMTCs. GFP-sorted CD8+ RMTCs were stimulated 7 days after transduction in the presence of splenocyte feeders on plates coated with 5 μg/mL AF6-88.5 anti-Kb, with conA, or cultured in the absence of stimulation. Stimulation-induced IFN-γ production was measured by Bioplex assay using anti-IFN-γ-coated beads. Data points are means of triplicate samples. Error bars show ± 1 SD; *, less than 1 ng/mL.
