Objective: To observe whether dendritic cells (DCs) transfected with recombinant adenovirus Ad5F35-LMP2 induces LMP2 specific immunity mediated by cytotoxic T lymphocytes in vitro.
Methods: Dendritic cells have been generated in vitro, and cocultured with autologous T cell after the DCs were infected with Ad5F35-LMP2, then the proliferation of the induced T cells and their cytotoxic activity against CNE-2 tumor cells which express EBV-LMP2 protein on membrane were assessed by MTT method.
Results: The dendritic cells could be transfected with Ad5F35-LMP2 and the CTL activated by Ad5F35-LMP2-DC could effectively suppress the proliferation of CNE-2 cells compared with control groups.
Conclusion: The dendritic cells transfected with recombinant adenovirus Ad5F35-LMP2 showed cytotoxicity effect by activating T lymphocytes.
