To explore a reliable diagnostic marker, we selected skin-grafted rabbits as an animal model to study peripheral blood mononuclear cell (PBMC) major histocompatibility complex 1 (MHC I) and MHC II gene mRNA in acute graft rejection (AGR).
METHODS: Fifteen New Zealand white rabbits were randomly divided into three groups to observe skin graft rejection: three rabbits were in the autograft control group; six rabbits in a cyclosporine (CsA) treated allografted group; and the other six rabbits in untreated allografted group. The CsA-treated allografted group was given CsA (5 mg/kg) daily intramuscularly. PBMC samples were obtained every 2 days to detect by real-time polymerase chain reaction, PBMC MHC I and MHC II gene mRNA.
RESULTS: MHC I and MHC II gene mRNA levels did not show any obvious change in the autografted controls. MHC I gene mRNA levels showed a slow increase in the CsA-treated allografted group, but no obvious change in the untreated allografted group. MHC II gene mRNA reached the highest level at 2 to 3 days before graft rejection appeared macroscopically in the CsA-treated allografted group and untreated allografted group, then decreasing to a low level.
CONCLUSION: Compared with MHC I gene mRNA expression, PBMC MHC II gene mRNA expression may be considered to be an earlier marker for AGR. | | Language | eng | | Pub Type(s) | Journal Article
