The goal of adoptive T cell therapy in cancer is to provide effective antitumor immunity by transfer of selected populations of tumor Ag-specific T cells. Transfer of T cells with high TCR avidity is critical for in vivo efficacy. In this study, we demonstrate that fluorescent peptide/MHC class I multimeric complexes incorporating mutations in the alpha3 domain (D227K/T228A) that abrogate binding to the CD8 coreceptor can be used to selectively isolate tumor Ag-specific T cells of high functional avidity from both in vitro expanded and ex vivo T cell populations. Sorting, cloning, and expansion of alpha3 domain mutant multimer-positive CD8 T cells enabled rapid selection of high avidity tumor-reactive T cell clones. Our results are relevant for ex vivo identification and isolation of T cells with potent antitumor activity for adoptive T cell therapy.
