| Research Abstract |
Outcomes of tumor treatment have been improved by development of multidisciplinary treatment. But, innovative tumor treatment strategy is eagerly anticipated. We proposed new strategy for tumor immunotherapy using cell reprogramming technology. In this study, we combined donor lymphocyte infusion (DLI) therapy and cell reprogramming technology. To do new DLI therapy, iPS cells are established from bone marrow donor cells. Usually, DLI treatment need donor lymphocyte on every treatment course, but this novel strategy make possible to do a continuous DLI treatment independent of lymphocyte donor. Then, it make possible to obtain T cell for DLI therapy every time you need. To test this concept, we established mice therapeutic model for leukemia relapse after bone marrow transplantation, and then we applied this new DLI treatment for this mice model. The mice survival were prolonged significantly depending on treatment frequency. It need more analysis to understand the response mechanisms.
