Brief Summary
Immunosuppressive drugs can be successfully withdrawn in a fraction of liver transplant patients. Specific peripheral blood gene expression markers can be employed to select patients with a high likelihood of being tolerant. In the current study the investigators propose to conduct a pilot non-randomized prospective study in which gradual weaning of immunosuppressive drugs will be offered to liver recipients exhibiting a favorable peripheral blood gene expression profile.

Eligibility Criteria
You may qualify if:
- Liver transplant recipients with at least 3 years of post-operative follow-up in whom gene expression pattern changed from non-tolerant to tolerant under sirolimus treatment.
- Feasibility of performing very frequent (every 2-3 weeks) clinical follow-up visits.
- No history of graft rejection during the previous 12 months.
- Basal liver biopsy without signs of rejection
- Stability of liver graft function, defined as: a) normal liver function tests (AST, ALT, ALP, GGT) during at least 6 months; or alternatively b) minor alterations in liver function tests that have not changed over the previous 6 months (AST/ALT \< 2 fold normal levels; ALP \< 1.5 fold normal levels; GGT \< 2 fold normal levels; bilirubin \< 2 mg/dL).
- Signature of informed consent.
You may not qualify if:
- Requirement of immunosuppressive treatment for an indication different to liver transplantation.
- Documented human immunodeficiency virus (HIV) infection.
- Liver-Kidney transplant recipients.
- History of liver autoimmune disease (autoimmune hepatitis, primary liver cirrhosis, primary sclerosing cholangitis)
- Active hepatitis C virus infection as defined by positive serum HCV-RNA.
