(A) Survival of LCMV-c13-infected B6 mice treated with anti-IFNAR 1 day prior to infection, anti-PD-L1 (days 0, 2, 4, 6, and 8), or both. Data pooled from 3 experiments with n > 6 mice per group are shown.
(B and C) Frequencies of total CD8 T cells, LCMV-gp33-specific CD8 T cells, and PD-1+ cells in indicated PBMC populations on 8 dpi in LCMV-c13-infected B6 mice with indicated treatment. Representative plots (B) with mean ± SD from 2 experiments (C) are shown.
(D) Plasma LCMV viral RNA load in LCMV-c13-infected B6 mice with indicated treatment from 2 experiments shown with median.
(E) Macroscopic images of spleen and splenocyte counts of LCMV-c-13-infected B6 mice with indicated treatment as in (A) on 22 dpi. Data from two experiments are shown.
