| Research Abstract |
The purpose of this study was to analyze the mechanisms of theinduction of operational tolerance in clinical liver transplantation by the intra-portaladministration of donor specific antigen and make the new method of induction of toleranceby hepatic stem cell. In the basic examination, the CD133+ NCAM+ human hepaticstem/progenitor cell was recognized around the region with existence of ductular reactionin the human liver with chronic or acute hepatitis. Especially, its existence was moreclearly in the human liver with higher hepatic injury. However, it was not recognizedin the normal human liver. In the immunological analysis of intra-portal administrationof super donor antigens, the population of FoxP3^+/CD4^+CD25^+ regulatory T cells increasedin the transplant patients with no immunosuppressants.
Treg. cells increased in the patients above MELD score 20. It was proved that the graspof preoperative immunological situation of transplant patients take the betteradministration of immunosuppressants.
