Use of Decellularized Porcine Liver for Engineering Humanized Liver Organ
New bioartificial liver devices are needed to supplement the limited supply of organ donors available for patients with end-stage liver disease. Here, we report the results of a pilot study aimed at developing a humanized porcine liver by transplanting second trimester human fetal hepatocytes (Hfh) co-cultured with fetal stellate cells (Hfsc) into the decellularized matrix of a porcine liver.Hepatic Overexpression of Heme Oxygenase-1 Improves Liver Allograft Survival by Expanding T Regulatory Cells
Heme oxygenase (HO)-1 protects transplanted organs from ischemia reperfusion injury and immune rejection. This study sought to investigate whether persistent overexpression of HO-1 in donor livers could improve the survival by expanding T regulatory cells in a rat model of orthotopic liver transplantation.Complications in Immunosuppressive Therapy of Liver Transplant Recipients
In liver transplantation (LT), modern immunosuppressive protocol is focused on early corticosteroid (CS) weaning. The aim of the study was to investigate all early transplant-related complications using Clavien grading system, in order to identify a significant relation in two homogenous groups of consecutive liver transplanted patients, only different for steroid avoidance in immunosuppressive regimen.Diazoxide Suppresses Hepatic Ischemia/Reperfusion Injury After Mouse Liver Transplantation by a BCL-2-Dependent Mechanism
Ischemia-reperfusion injury (IRI) is responsible for primary liver dysfunction and failure after transplantation. The mitochondrial pathway appears to be involved in liver ischemia-reperfusion injury. Mitochondrial ATP-sensitive K (mitoKATP) channels play a central role in protecting the heart from injury in ischemic preconditioning. The selective mitoKATP channel agonist diazoxide potently reduced mitochondrial injury by preventing cytochrome c loss from the intermembrane space. Therefore, this study sought to determine whether diazoxide can attenuate ischemia-reperfusion injury induced by orthotopic liver transplantation (OLT) in mice.Hypothermic Machine Preservation Attenuates Ischemia/Reperfusion Markers After Liver Transplantation: Preliminary Results
Hypothermic machine perfusion (HMP) has shown significant benefits in renal transplantation but is still in its infancy in liver transplantation. Potential benefits include diminished preservation injury and improved early graft function.Cytoprotective Effects of Human Interleukin-10 Gene Transfer Against Necrosis and Apoptosis Induced by Hepatic Cold Ischemia/Reperfusion Injury
Apoptosis as well as necrosis may play an important role in hepatic ischemia/reperfusion (I/R) injury. Interleukin 10 (IL-10), a Th2 type cytokine, modulates inflammatory responses by inhibiting the production of proinflammatory cytokines. The study focused on cytoprotective and antiapoptotic pathways to assess mechanisms by which gene transduction of human IL-10 (hIL-10) may renders grafts resistant to the cold I/R injury.
