| Research Abstract |
In this project, 1)Ideal antigen source and conditioning of dendritic cells (DC) 2) Application of tumor-DC cell fusion 3) Ideal condition of allogenic bone marrow transplantation (ABMT) 4)Application of apoptotic tumor cell for antigen source, for DC cancer immunotherapy (DCI) were investigated.
1) Total RNA extracted from tumor cells were introduced to DC using RNA Transmessenger Kit. Transcribed GFP mRNA transfection efficiency (7.2%) was observed. Stimulation with anti-CD40 mAb as maturation signal, 1 hr after RNA pulse for 3 hrs, resulted in efficient induction of antitumor immune response.
2) DC was electrically fused with D5 tumor cells using BTX electric pulse generator. Fusion efficiency was approximately 50%. Intra-lymph-nodal injection of fusion cells in mice bearing D5 pulmonary metastases resulted in significant reduction of the metastasis. Also, potent effector cells were generated in vitro from naive spleen cells when stimulated with the fusion cells.
3) Optimal dose of total body irradiation (TBI) for conditioning of ABMT-DCI was examined. Optimal dose of TBI was found to be 800-1000R.
4) Induction of tumor-cell apoptosis by an agonistic monoclonal antibody to DR5, the apoptosis-inducing receptor for TNF- related apoptosis-inducing ligand (TRAIL), combined with T-cell activation by agonistic monoclonal antibodies to the costimulatory molecules CD40 and CD137, potently and rapidly stimulated tumor-specific effector CD8+ T cells capable of eradicating preestablished tumors.
