CD45RA and CCR7 coexpression by BMLF1- and pp65-specific CD8⁺ T cells. (A) Representative profiles of CD45RA and CCR7 coexpression by BMLF1 tetramer⁺ (left panel) and pp65 tetramer⁺ (right panel) CD8⁺ cells. (B) Percentage of CD45RA⁺CCR7⁺, CD45RA^–CCR7⁺, CD45RA^–CCR7^–, and CD45RA⁺CCR7^– cells among BMLF1- and pp65-specific CD8⁺ T cells from 8 EBV- and CMV-seropositive HLA-A2 donors.
