Figure 2.
(a) IL-2 production by a representative short-term CD4 T-cell line L-EB, with different concentrations of histone H449–63 peptide-pulsed autologous EBV B-cell APCs. Stimulation with 0.01–100 μM peptide showed significant differences (*P < 0.05 at 0.01 μM, Student’s t test) from background (T cells plus APCs cultured without peptide). (b) An example of MHC class II–dependent recognition of nucleosomal peptides. Presentation of H449–63 peptide by autologous EBV B cells to short-term T-cell line L-EB was inhibited mainly by anti-DR mAb.
