['Adoptive cell transfer is described as an innovative and challenging option for the treatment of malignant melanoma. In the current study, the generation and expansion of telomerase-specific T-cells for adoptive cell transfer and their use in a syngeneic pancreatic carcinoma mouse model was investigated.', 'Telomerase-specific T-cells were generated either in vitro by coculture of human lymphocytes with telomerase-peptide-pulsed dendritic cells or in vivo by injection of peptide plus adjuvant into C57BL/6 mice. Spleens were harvested after immunization and lymphocytes were expanded in the presence of feeder cells. T-cells were tested in vitro against human leukocyte antigen (HLA)-matched, telomerase-positive pancreatic carcinoma cells. Tumor-bearing (subcutaneous) mice pretreated with cyclophosphamide were injected intravenously with the expanded cells.', 'It was possible to generate and expand telomerase-specific T-cells with cytotoxic activity. The protocol did not work as well in the murine setting. However, adoptive cell transfer with murine antigen-specific T-cells delayed disease progression in tumor-bearing mice significantly.'] Do telomerase-specific T-cells kill pancreatic tumor cells in vitro and in vivo?
