The hierarchy of CD8 T-cell populations specific for different EBV epitopes is similar in allo-PBSCT recipients and their respective donors.

PBMCs were isolated from allograft recipients A-E at the indicated times following transplantation and stained with HLA-A2 or HLA-B8 tetramers, each complexed with 3 different EBV epitopes, as indicated below each bar graph. Donor PBMCs were stained with the same tetramers, and the frequency of EBV-specific T cells was determined. The percentage of CD8 T cells staining with HLA tetramers is indicated on the y-axis.
