B7-H1 dampens CD4 T-cell activity during priming. (A-D) Relative transcript levels of (A) interferon (IFN)-γ, (B) interleukin (IL)-10, (C) IL-2 (D) and IL-21 in CD44^hiCD62L^lo CD4 T cells purified by fluorescence-activated cell sorting from cervical lymph nodes of wild-type (WT) or B7-H1^−/− mice at 5 days post-infection. Transcript levels are relative to GAPDH × 1000. Data depict the mean ± SEM of two independent experiments.
