HLA-A2402-restricted and carcinoembryonic-antigen(CEA)-specific cytotoxic T lymphocytes (CTL) were induced by culturing human peripheral blood mononuclear cells (PBMC) on formalin-fixed autologous adhesive PBMC that had been loaded with CEA-bound latex beads. The CTL killed the CEA-producing HLA-type matched cancer cells, but not the non-producers of CEA, at an effector/target ratio of 10 within 24 h. On the basis of available HLA-A24-binding peptides, we have also attempted to identify the epitope peptide recognized by the CTL. The peptide CEA652(9), TYACFVSNL, stimulated the CTL most strongly when pulsed on HLA-A2402-expressing target cells. The other nine peptides so far tested were also active, but less efficient in their effect on CTL. The CTL failed to kill target cells pulsed with the HLA-A2-binding CEA peptide, CAP-1. The CTL were also generated on the fixed adherent cells previously pulsed with the peptide CEA652(9). Cytotoxic activity of the CTL was inhibited by monoclonal antibodies against CD3, CD8, and MHC class I molecules. These results suggest that human autologous CTL will be inducible on the autologous fixed PBMC without use of the cultured target cancer cells if tumor antigenic protein is available.
