CMV-specific CD8⁺ T cells are not deleted by allodepletion. The figure shows FACS analysis following staining of either unmanipulated PBMCs (right and center columns) or allodepleted cells (left column) from 4 HLA-A2–positive, CMV-seropositive donors with IgG PE (left column) or an HLA-A2–CMV pp65 tetramer (center and right columns). The percentages of tetramer-positive cells as a proportion of CD8⁺ cells with isotype subtracted are shown.
