Outline of Final Research Achievements |
We evaluated the effect of donor antigen specific immunosuppressive anergy cells on chronic rejection such as transplant arteriosclerosis. First, we confirmed that the immunosuppressive anergy cells were successfully generated from lymphocytes of healthy volunteer. Next, the severe immunodeficient NSG mice were reconstituted human PBMC and investigated the proliferation of human PBMC in vivo by CFSE labeling technique. Also when another irradiated human lymphocytes were injected into reconstituted mice as a donor antigen stimulation, the immune responses were observed by Ki-67 staining after stimulation. Further, to establish a human vessel transplant model, murine aortic transplant model has been established. In addition we evaluated the relationship between anti-donor antigen antibody and chronic rejection in liver transplant clinical setting.
