Figure 2 Persistence of CMV- and EBV-specific CD8 T cell clones, using allophycocyanin (APC)-labeled HLA-viral peptide tetramer analysis. Both patients were positive for HLA-A∗0201; thus, we used NLVPMVATV (CMV peptide) conjugated to HLA-A∗0201-APC tetramer and GLCTLVAML (EBV peptide) conjugated to HLA∗0201-APC tetramer (both purchased from Beckman Coulter) to stain CMV- and EBV-specific clones in blood mononuclear cell specimens by flow cytometry. The cells also were stained by CD3-phycoerythrin antibody and CD8-fluorescein isothiocyanate (FITC) antibody. The density dot plots, showing tetramer-APC fluorescence on the x-axis and CD8-FITC fluorescence on the y-axis, were gated on CD3+CD8+ lymphocytes. The CMV tetramer staining of the cells from the MS patient (who was CMV-seronegative) served as a negative control for setting the border between tetramer-positive and tetramer-negative cells. The percentages of the tetramer-positive cells (of total CD8 T cells) are shown, indicating that even though the percentages varied, the same EBV-specific CD8 clones in both patients and the same CMV-specific CD8 clone in the CMV-seropositive patient were present both pretransplantation and posttransplantation.
