| Research Abstract |
In the present study, we studied experimental orthotopic liver transplantation (OLT) model. We recognized that the Kamada technique and a new splint technique for hepatic artery reconstruction was convenient technique for rat OLT. We demonstrated that hepatic artery reconstruction prevented ischemic graft injury, inhibited graft rejection, and mediated long-term graft acceptance in rat OLT. In rejection of OLT, acute antibody-mediated rejection (AMR) clould develop in OLT and was characterized by endothelial cell injuries in microvasculature and by bile duct and hepatic cell degeneration and necrosis. In addition, chronic AMR could also involve in chronic rejection in OLT, and was characterized by typical late morphological changes with IgG deposition. In the development of tolerance in OLT, lymphangiogenesis may be involved in reduction of inflammation. Now we are studying the pathological characteristics of immune tolerance in rat OLT model.
