EBV and MMR statuses and PD-L1+, CD3+ and CD8+ cell counts. Analyses of immune markers in EBV+ and EBV− patients revealed that total, intraepithelial and stromal CD3+ (a) and total, intraepithelial CD8+ (b) T-cell lymphocytic infiltrates and PD-L1 expression (c) were more abundant in EBV+ patients than in EBV− patients. However, in patients with different MMR statuses, the differences in the numbers of CD3+ (d) and CD8+ (e) T-cell lymphocytic infiltrates and PD-L1 expression (f) were not statistically significant.
