Tissue culture supernatants were collected 24 and 48 hours after stimulation with anti-TCR and anti-CD28 and were assayed for IL-2, IL-10, and IFN-γ using capture ELISA as described in “Materials and methods.” The results shown concern IL-2 production after 24 hours of stimulation and IL-10 or IFNγ production after 48 hours of stimulation. IL-4 and IL-13 mRNA were detected by RT-PCR after stimulation for 24 hours.
ND indicates not determined; UND, undetectable.
