Brief Summary

Long-term immunosuppression carries potential adverse effects such as risk of infection, malignancy, renal insufficiency, diabetes and hypertension. In clinical liver transplantation, some liver transplant recipients maintain allograft function without immunosuppressive drugs. This is called as "operational tolerance". Many attempts have been made to identify immunological biomarkers predicting operational tolerant patients. Therefore, the investigators aimed to identify patients who have the potential to be operationally tolerant using biomarkers, withdraw immunosuppressant gradually and stop ultimately with monitoring of biomarkers.
