CD8+ T cells specific for subdominant epitopes from 8 dpi TG express granzyme B. Dispersed TG were stained for 1 h at room temperature with anti-CD45, CD8α, and tetramers loaded with sub-dominant epitopes followed by intracellular staining for granzyme B expression. A, Representative dot plots of granzyme B expression of select HSV-specific CD8+ T cells. B, Bars represent percentage of peptide-specific CD8+ T cells that express granzyme B ± SEM (n = 4) from two independent experiments. Granzyme B expression is lower in non-gB-specific CD8+ T cells compared with gB-specific CD8+ T cells. The p value for all specificities is <0.025.
