PG - 253-7 AB - Sixteen mer peptide, which spans the junctional region of the acute lymphoid leukemia (ALL)-specific minor bcr-abl fusion protein and contains a motif that can bind to human leukocyte antigen (HLA)-A24, was constructed. We tried to generate Philadelphia chromosome 1 (Ph1) positive ALL-specific cytotoxic T lymphocytes (CTLs) from eight normal HLA-A24+ individuals with peptide-pulsed autologous dendritic cells (DCs). CTLs could be generated from the mononuclear cells (MNCs) of a single donor, which could kill peptide-pulsed autologous DCs and two A24+ ALL lines, while an HLA-A24+ CML line was only weakly killed and unpulsed DCs or the control lines Daudi or K562 were not recognized. Those CTLs consisted predominantly of CD8+ T cells whose cytotoxicity could be neutralized by monoclonal antibodies to HLA-class I or HLA-A24, and also produced interferon (IFN)-gamma after being stimulated with peptide-pulsed DCs.
