Figure 2From: Identification and characterization of H-2d restricted CD4+ T cell epitopes on Lpp20 of Helicobacter pyloriInhibition of Th cells proliferation by MHCII-specific mAbs. Purified CD4+ T cells from mice primed with rLpp20 were stimulated with peptides (1.25 μg/ml) in the presence of mAbs specific for I-Ad, I-Ed, or MHCImolecules. Cultures incubated with peptides without mAbs were used as controls. The proliferation of the cells was quantified in triplicate by 3H-TdR incorporation. The values shown were means ± SD of three independent experiments.Back to article page
