Plasma Cells Are Not Necessary for Regulatory B Cells and Preventing Their Differentiation Markedly Prolongs Allograft Survival
Thomas E Starzl Transplant Institute, University of Pittsburgh, Pittsburgh, PA
*Purpose: Plasma Cells (PCs) are the primary source of circulating antibodies. PCs were reported to be the major source of B-cell lineage IL-10, and absence…2020 American Transplant Congress
T Follicular Regulatory Cell Deficiency Enhances Secondary T Follicular Helper Cell Responses after Transplantation
*Purpose: Deleterious alloantibodies result from T follicular helper (Tfh) cell-driven germinal center (GC) reactivity. T follicular regulatory (Tfr) cells are a subset of regulatory T…2020 American Transplant Congress
Sialoadhesin Mediates the Adhesion of Human RBC to Porcine Macrophages from Genetically Engineered Pigs
*Purpose: The sequestration of human RBC is prominent after liver and lung xenotransplantation. Rees et al previously implicated porcine sialoadhesin in adhesion of human RBC…2020 American Transplant Congress
Normothermic Machine Perfusion of Genetically Modified Pig Livers with Human Blood
*Purpose: Barriers to pig-to-human liver xenotransplantation remain, including profound thrombocytopenia, coagulopathy, and rejection. We utilized ex-vivo liver xenoperfusion with human blood to study the human…2020 American Transplant Congress
Estrogen Receptor Beta Deletion in the Vascular Endothelium is Protective in Renal Ischemia Reperfusion Injury
*Purpose: Renal ischemia reperfusion injury (IRI) is a major contributor to early allograft dysfunction (EAD) in kidney transplantation. We previously identified lower rates of EAD…2020 American Transplant Congress
Post-Transplantation Lymph Node Fibrosis: Significant Implications in Transplant Tolerance
1Brigham and Women's Hospital, Boston, MA, 2University of Maryland School of Medicine, Boston, MA
*Purpose: Lymph nodes (LNs) have been regarded as primary activation sites for alloimmunity following transplantation, but our group has revealed an additional dimension to their…2019 American Transplant Congress
The mIR17-92 Cluster Promotes Costimulation Resistant Effector Memory T Cell-Mediated Alloresponses
1Surgery, Duke University, Durham, NC, 2Immunology, Duke University, Durham, NC
*Purpose: CD57 expression has been shown to identify a subset of memory T cells that are resistant to CD28/B7 costimulation blockade (B7CoB). This study was…2019 American Transplant Congress
CHOP Deficiency Attenuated Acute Liver Injury by Promoting Macrophage M2 Polarization via ATG5-Mediated Autophagy Activation
The First Affiliated Hospital of Nanjing Medical University, Nanjing, China
*Purpose: Critical roles of CCAAT-Enhancer-Binding Protein Homologous Protein (CHOP) have been found in mediating acute liver injury. The aim of this study is to determine…2018 American Transplant Congress
CCAAT-Enhancer-Binding Protein Homologous Protein Promotes Liver Ischemia and Reperfusion Injury by Inhibiting Beclin-1-Mediated Autophagy in Hepatocytes
Background and Aims:Critical role of endoplasmic reticulum (ER) stress has been found in ischemia and reperfusion(IR) injury models. However, the role of CCAAT-Enhancer-Binding Protein Homologous…2018 American Transplant Congress
TGR5-Mediated AMPK/mTOR Signaling Regulates Macrophage Migration and Polarization in Liver Ischemia Reperfusion
Background: Although the plasma membrane-bound G protein–coupled bile acid receptor (TGR5) exerts protective roles in various inflammatory diseases, little is known about the effects and…
