Disulfide HMGB1 Reprograms Macrophages to Induce Alloimmunity via TLR4 and TLR9 Pathways Following Ischemia-Reperfusion Injury in Human Orthotopic Liver Transplantation
*Purpose: Human hepatocellular damage caused by ischemia reperfusion injury (IRI) generates the disulfide form of HMGB1 (diS HMGB1), eliciting myeloid cell activation and proinflammatory cytokine…2022 American Transplant Congress
Final Report of the Use of α-Lipoic Acid in Liver Transplantation to Prevent Ischemia Reperfusion Injury
1Hospital Italiano, Buenos Aires, Argentina, 2CEFYBO, Buenos Aires, Argentina
*Purpose: The ischemia and reperfusion injury contributs to grafts deterioration and adverse post-transplant outcomes. The aim of the present study was to evaluate the safety…2021 American Transplant Congress
Accelerated Bronchiolitis Obliterans After Lung Transplant Promoted by an ATG16L1 Mutation is Coupled to Mitochondrial Damage and Metabolic Alterations in Monocyte-derived Antigen Presenting Cells
1Washington University, Saint Louis, MO, 2UT Southwestern Medical Center, Dallas, TX
*Purpose: Bronchiolitis obliterans (BOS) remains a major cause of death for lung transplant recipients, and the mechanisms that drive BOS remain poorly understood. It is…2021 American Transplant Congress
The Contribution of Disulfide-hmgb1 Released During Ischemia-reperfusion Injury to Pro-inflammatory Macrophage Polarization Following Liver Transplantation
Pathology and Lab Medicine, UCLA, Los Angeles, CA
*Purpose: Ischemia-reperfusion injury (IRI) during liver transplantation (LT) is a pro-inflammatory response linked to poorer outcomes, including increased alloimmunity, post-LT. We previously showed that post-reperfusion…2020 American Transplant Congress
Accelerated Bronchiolitis Obliterans after Lung Transplant Promoted by the ATG16L1 rs2241880 Mutation is Coupled to Mitochondrial Damage and Metabolic Alterations in Monocyte-Derived Alveolar Macrophages
*Purpose: Bronchiolitis obliterans (BOS) remains a major cause of death for lung transplant recipients, and the mechanisms that drive BOS remain poorly understood and require…2020 American Transplant Congress
Oral Administration of Nano-Sized Silicon Particles Regulates Gene Expression Related to Oxidative Stress and Attenuates Rat Renal Ischemia Reperfusion Injury
*Purpose: Organ ischemia reperfusion injury (IRI) is unavoidable in kidney transplantation and induces reactive oxygen species and causes organ damage. Although the effectiveness of hydrogen…2020 American Transplant Congress
Induction of Transplant Tolerance by Modulating the Metabolic Stress Pathways
Houston Methodist Research Institute, Houston, TX
*Purpose: T cell activation and effector differentiation precede graft rejection, and this process is associated with robust metabolic burst to meet the energy demand of…2020 American Transplant Congress
A Novel Polymer Product, APP-103, Reduces IRI-Induced Damage and Promotes Functional Improvement in Syngeneic Models of Renal Transplantation
*Purpose: Our data introduce APP-103 as a novel, non-toxic and site-activating therapeutic approach that effectively ameliorates the consequences of ischemia/reperfusion injury in solid organ transplantation.*Methods:…2019 American Transplant Congress
New Reactive Oxygen Species Scavenger Prevents Injury in Ischemia-Reperfusion Injury Model
University of Wisconsin, Madison, WI
*Purpose: Despite the success of preservation solutions, Ischemia-Reperfusion (IR) injury remains a significant problem for all solid organ transplants. As a result, an important, unmet…2019 American Transplant Congress
Ceria-Zirconia Nanoparticles as an Enhanced Antioxidant Attenuates Apoptosis of Human Kidney Proximal Tubular Epithelial Cells in Hypoxia
*Purpose: Ischemia/reperfusion injury, resulting from hypoxic damage within a graft, is the leading cause of delayed graft function and graft rejection. Various mechanisms have been…
