Outline of Final Research Achievements |
The purpose of this study is the permanent survival of allografts by means of the establishment of novel strategy of induction of postoperatively sensitized immune tolerance. We tested the effect of combined therapy of ①adoptive transfer of Treg cells proliferated in in vitro culture system, so called “Treg bank” and ②the gene transfection of MF-1, which protect the kidney tissue from the all sorts of injuries after engraftment. We have obtained the following results so far. The first, "the establishment of MF-1 gene transfection to the transplanted kidney tissue, which establish the protective gene transfer therapy of the allografts. Second, the improvement of immune tolerance induction rate by adoptive transfer of Treg supplied by Treg bank in which Treg are proliferated in in vitro system. Those results may realize the establishment of new immune tolerance method and the renal transplant without using immunosuppressive agents may be feasible.
