N2 - As there is still a high mortality of the large cell anaplastic non Hodgkin lymphoma (ALCL) (between 40-70%, depending on prognostic factors) there is a need for new therapeutic approaches. Therefore, we studied different strategies for cancer immunotherapy in an immunogenic ALCL tumor model system: A murine IL-9 dependent T cell line was transfected with IL-9 cDNA, resulting in an autonomous growing T cell line designated G6BB, which had a high tumor incidence after injecting of as few as 10(4) cells subcutaneously into syngeneic C57Bl/6 mice. Tumor growth, dissemination, histology, and immunohistochemistry were similar to human ALCL. This mouse model provides an immunogenic in vivo system to investigate antitumor immunotherapies. In order to increase antigen recognition by T cells and T cell activation, we administered tumor bearing mice cell-based cancer vaccines with irradiated tumor cells alone or in combination with immunostimulating CpG-Oligonucleotides, a combination of Th1 cytokines and Th2 cytokine antibodies (IL-12, IFN-gamma, GM-CSF, Anti-IL-10) (after detecting a Th2 cytokine profile in G6BB), or the recall antigens diphtheria, pertussis, and tetanus.
