CD103⁺ and CD69⁺ CD8 T cells express Bcl-2 within the infected brain. Cells were isolated from the brains of MCMV-infected WT and PD-L1 KO mice at 30 dpi and evaluated for the expression of the pro-survival molecule Bcl-2 on CD103⁺CD69⁺-gated CD8⁺ T cells. a Representative flow cytometric analysis of intracellular expression of Bcl-2 expression in CD103⁺CD69⁺-gated CD8⁺ T cells among WT and PD-L1 KO animals at 30 dpi. b Pooled data present the percentage (mean ± SD) of Bcl-2 expression on CD103⁺CD69⁺ cells among different groups of mice at the indicated time point (n = 3 from both groups). *p < 0.01 WT versus PD-L1 KO for Bcl-2 expression in CD69⁺CD103⁺ cells at 30 dpi
