Following organ transplantation, lifelong immunosuppressive therapy is required to prevent the host immune system from destroying the allograft. This can cause severe side effects and increased recipient morbidity and mortality. Complete cessation of immunosuppressive drugs has been successfully accomplished in selected transplant recipients, providing(More)
Pathogen-induced immune responses prevent the establishment of transplantation tolerance in experimental animal models. Whether this occurs in humans as well remains unclear. The development of operational tolerance in liver transplant recipients with chronic hepatitis C virus (HCV) infection allows us to address this question. We conducted a clinical trial(More)
Hepatic expression of iron homeostasis genes and serum iron parameters predict the success of immunosuppression withdrawal following clinical liver transplantation, a phenomenon known as spontaneous operational tolerance. In experimental animal models, spontaneous liver allograft tolerance is established through a process that requires intra-hepatic(More)
Ischemia/reperfusion injury (IRI), inherent in liver transplantation (LT), is the main cause of initial deficiencies and primary non-function of liver allografts. Living-related LT was developed to alleviate the mortality resulting from the scarcity of suitable deceased grafts. The main problem in using living-related LT for adults is graft size disparity.(More)
Allograft tolerance has been successfully induced in many experimental animal models of transplantation. Liver allografts are indeed spontaneously accepted in most mouse and rat strain combinations. This contrasts with the difficulties of inducing transplantation tolerance in humans: aggressive conditioning is required to intentionally establish(More)
Acute cellular rejection occurs frequently during the first few weeks following liver transplantation. During this period, its molecular phenotype is confounded by peri- and postoperative proinflammatory events. To unambiguously define the molecular profile associated with rejection, we collected sequential biological specimens from 55 patients at least 3(More)
Liver transplantation remains the treatment of choice for patients with end-stage liver disease. However, allograft availability continues to be a problem, and extending the criteria for organ acceptance is key. Deceased donors after electrical accidents, as well as electricity-traumatized allografts, are not common but should be considered suitable. This(More)
