Figure 1. Type I IFNs promote Bcl6 expression.
(A, C, D) Bcl6 and T-bet staining in CD4+ T cells cultured in the presence of the indicated cytokines for 5 days. (B) Relative mRNA expression of Bcl6, T-bet, Maf, Irf-4, and Batf was evaluated by qPCR. The data (mean ± SD) are representative of three independent experiments. (E, F) Bcl6 and T-bet staining in CD4+ T cells cultured with increasing doses of IFN-α or IFN-β for 5 days (E) or in neutral conditions or IFN-β for the indicated number of days (F). Data (mean ± SD) are from duplicate cultures of three independent experiments (n=6). The plots are representative of three independent experiments. *, p<0.05; **, p<0.01.
