Response to immunogenic peptides in the presence of Tregitope 167. Responses to antigen restimulation following initial stimulation with a pool of immunogenic peptides derived from C3d protein (■); C3d peptides plus Tregitope 134 (); and C3d peptides plus Tregitope 167 (
). Responses are shown as fold increase over background, which was no stimulus (control) in the secondary incubation. The respective baseline (background) values in pg/ml are indicated within the x-axis labels. There was no difference in levels of IL-4, TNFα, or TGFβ1 (data not shown).
