Acute Cellular Rejection Is Associated With Matrix Metalloproteinase-2 Genotype Chimerism After Orthotopic Liver Transplantation

Chimerism after OLT can be found in liver biopsy specimens and in peripheral blood. MMP donor-recipient polymorphism mismatches are good markers for assessing chimerism after OLT. In the multivariate analysis, liver chimerism in MMP-2 was found to be significantly associated with the development of ACR after OLT.
