The Presence of Foxp3 Expressing T Cells Within Grafts of Tolerant Human Liver Transplant Recipients

This is the first report showing that CD4Foxp3 cells are present within grafts in a subset of tolerant patients after human liver transplantation. A prospective study is needed to elucidate whether the assessment of intragraft expression of Foxp3 protein, but not Foxp3 mRNA, can aid the identification of living-donor liver-transplantation recipients who can successfully withdraw IS.
