Deletion of AIF-1 Promotes Kidney Reparative Macrophages and Prevents Fibrosis
Duke University School of Medicine, Durham, NC
*Purpose: A major etiology contributing to poor allograft survival is the inevitable ischemic insult it incurs during transplantation. Macrophages are key players in ischemia-reperfusion injury,…2022 American Transplant Congress
The Role of HNF4α in Renal Ischemia Reperfusion Injury
Toronto General Hospital Research Institute, Toronto, ON, Canada
*Purpose: Ischemia reperfusion injury (IRI) affects all solid organ transplants and impairs renal graft function. However, the mechanisms by which IRI affects grafts are incompletely…2022 American Transplant Congress
Estrogen Receptor Beta Deletion is Protective in Renal Ischemia Reperfusion Injury but Pharmacologic Inhibition of Estrogen Receptor Beta is Not
*Purpose: Renal Ischemia Reperfusion Injury (IRI) contributes substantially to delayed graft function (DGF) in kidney transplantation. Prior work by our group has shown lower rates…2022 American Transplant Congress
Implications of Accumulated Cold Time for US Kidney Transplantation Offer Acceptance
*Purpose: Reducing discard is a current focus in US transplantation of deceased donor kidneys. One cause for the discards is the avoidance of protracted cold…2022 American Transplant Congress
Abnormal Kidney T Cell Metabolism During Ischemia Reperfusion Injury Can Be Modified to Improve Organ Structure and Function
Johns Hopkins University School of Medicine, Baltimore, MD
*Purpose: T cells play an important role in the pathophysiology of kidney ischemia reperfusion injury (IRI). Metabolic programming of T cells, a rapidly evolving field,…2022 American Transplant Congress
Novel Immune Checkpoint Molecule TIGIT Mediates Experimental Kidney Ischemia Reperfusion Injury
Medicine, Johns Hopkins University, Baltimore, MD
*Purpose: T cells play both pathogenic and reparative roles in kidney ischemia reperfusion injury (IRI) but the molecular mechanisms regulating kidney T cell functions are…2022 American Transplant Congress
Evolution of Donor-Derived Cell-Free DNA During the First Week After Surgery Predicts Renal Function Recovery After Kidney Transplantation
1Hospital Clínic de Barcelona, Barcelona, Spain, 2Hospital Clinic de Barcelona, Barcelona, Spain
*Purpose: Donor-derived cell-free DNA (ddcfDNA) is usually employed starting from the second week after kidney transplantation (KT), as its earlier increase can be due to…2022 American Transplant Congress
Autoimmune Responses to DNA Topoisomerase I Exacerbate Renal Allograft Injury
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Immune responses to self antigens develop following organ transplantation. Multiple studies describe correlations between pre-existing or de novo autoimmune responses and poor transplant outcome.…2022 American Transplant Congress
Artificial Mitochondria Transfer to Mitigate Ischemic Damage in an In Vitro Model of Tubular Injury and in an Ex Vivo Porcine Model of DCD Renal Transplantation
*Purpose: We aimed at assessing whether artificial mitochondrial transfer (AMT) mitigates renal injury in an in vitro model of tubular damage and in an ex…2022 American Transplant Congress
Delivery of Extracellular Matrix Targeted Regulatory T Cells by Novel Nanofiber Coatings for Transplantation Therapies
*Purpose: Regulatory CD4+CD25+FOXP3+ T cells (Tregs) have been shown to induce tolerance in transplantation models and can mitigate transplant rejection or injury following ischemic reperfusion…
