Interventions/Control_1

The liver transplant recipient is given cyclophosphamide (40 mg/kg, iv) on postoperative days (POD) 5, and ex-vivo generated regulatory T cells on POD 13. Postoperative immunosuppression is with conventioal method. The immunosuppressant is reduced to 3/4 daily dose of the twice daily dose at 6 months, which is reduced to 3 times/week, 2 times/ week and 1 time/week every 3 months after confirming normal graft function and liver biopsy. The immunosuppressant is completely discontinued by 18 months after transplantation.
