Abstract:
Designer T cells expressing transgenic T cell receptors (TCR) with anti-tumor specificity offer new treatment options for cancer patients. We developed a three phase procedure to identify T cells of high avidity based on the fact that T cells recognizing peptides presented by allogeneic MHC efficiently kill tumor cells. Autologous dendritic cells (DC) are co-transfected with ivt-RNA encoding an allogeneic MHC molecule and a selected antigen to allow them to express allogeneic MHC-peptide complexes that activate allo-restricted peptide-specific T cells. This approach provides great flexibility for obtaining high-avidity T cells as potential sources of TCR for adoptive T cell therapy.
