(A) Ifnar1fl/fl;Mb1Cre, Ifnar1fl/fl;CD4Cre, Ifnar1fl/fl;CD11cCre, Ifnar1fl/fl;NCR1Cre, and Ifnar1fl/fl littermate control mice were infected with LCMV Cl13. Viral titers in serum were measured by focus-forming assay (FFU) at indicated time points. (B to E) Ifnar1fl/fl;NCR1Cre and littermate control mice were infected with LCMV Cl13. Frequency and number of GP33- or GP276-specific CD8 T cells (B), GP33-specific cytokine-producing CD8 T cells (C), GP61-specific cytokine-producing CD4 T cells (D), and TFH, GCB, and plasma cells (E) in the spleen were analyzed at day 6 after infection. Statistical comparisons were performed using two-way ANOVA followed by Mann-Whitney U test with Holm-Šídák multiple testing correction (A) or two-tailed Student’s t test (B to E).
