D indicates donor; and R, recipient after HSCT.

For pp65 and IE-1 stimulations (supplemental Figure 2), the dominant peptide targeted in matrix experiments was used as the stimulatory antigen in each case (Table 3): *EDVPSGKLFMHVTLG, **ARNLVPMVATVQGQN, ***LSEFCRVLCCYVLEE. For other data shown, complete ORF peptide pools were used as the stimulus.

Color codes denote identical clonotypes between each donor-recipient pair.
