Methylation status of CD4+CD25+CD127-IFNγ+ Treg in transplant patients and healthy controls.

Approximately, half of male kidney transplant recipients with good long-term stable graft function show mainly methylated (>75% Foxp3 TSDR methylation) IFNy+ Treg in the blood whereas the other half of male patients possess in addition a sizeable proportion of demethylated (11–75% Foxp3 TSDR methylation) IFNy+ Treg suggesting that they possess IFNy+ Treg with transient as well as stable Foxp3 expression.
