| Outline of Final Research Achievements |
Withdrawal from immunosuppressant by induction of tolerance is the ultimate goal in liver transplantation. It is speculated that together with Kupffer cells, hepatic stellate cells play an important role in maintaining the immune tolerance environment. There have been no reports on intrahepatic immunity and hepatic stellate cells, and its mechanism is unknown. Regarding immune regulation and endoplasmic reticulum stress, the PERK pathway, which is one of the endoplasmic reticulum stress pathways, has been reported to inhibit apoptosis via CHOP induction of macrophages responsible for innate immunity. It is also reported that it is involved in maintaining quality of hematopoietic stem cells. The purpose of this study is to clarify the role of hepatic stellate cells and the involvement of endoplasmic reticulum stress in liver transplantation immunity.
