HLA-A2–dimer/peptide staining of T cells from a representative CLL patient (CLL-14) before and after 28 days of in vitro culture recognizing FMOD-derived peptides and MAGE-3–derived peptide. T cells were expanded using native CLL cells as APCs without the addition of exogenous peptide. The numbers given are the percentage of CD8-positive T cells reacting with the FMOD(F1-F4)–or MAGE-3–specific HLA-A2-dimer/peptide.
