Abstract
Dendritic cells (DC) are potent antigen-presenting cells and play a pivotal role in T-cell-mediated immunity. From a HLA-A2+ patient with histologically verified adenocarcinoma of the pancreas a stable cell line could be established. DC were generated and pulsed with autologous tumor cell lysate. Autologous T cells were stimulated with tumor-cell lysate-pulsed DC in weekly intervals. High levels of IL-12 and IFN-γ were detected in the supernatants, indicating a T-helper type 1-immune response. The cytokine profile was associated with the expression of activation marker CD69. CTL-mediated cytotoxicity was assessed and revealed high specificity for autologous pancreatic cancer cells which was HLA-class I restricted. This model can be used in the development of DC-based tumor vaccines.
