PG - 333-41 LID - 10.1016/j.canlet.2008.06.025 [doi] AB - Dendritic cells (DCs) have been widely used as cancer vaccines. However, their functional abilities have often been suppressed by tumor-secreted immunosuppressants such as transforming growth factor-beta (TGF-beta). We developed a new strategy using a TGF-beta insensitive DC as cancer vaccine. The effect of this vaccine was tested in a murine pulmonary metastases model of renal carcinoma (Renca). Tumor lysate-pulsed DCs (TP-DCs) were infected with retrovirus containing gene of dominant negative TGF-beta type II receptor (TbetaRIIDN) and thus made TGF-beta insensitive. Vaccination of the mice bearing Renca pulmonary metastases with the TbetaRIIDN TP-DC induced powerful tumor-specific cytotoxic T lymphocyte (CTL) responses, suppressed pulmonary metastases, and prolonged survival times. These results suggest TGF-beta-insensitive TP-DC vaccine can be used to enhance the antitumor efficacy of DC vaccine.
