Deficiency of the Transcription Factor Satb1 in T Cells Promotes Solid Organ Allograft Survival
*Purpose: Conventional CD4+ T cells are key effectors of allograft rejection and novel therapies limiting their response may hold promise in the context of organ…2018 American Transplant Congress
A 3C Approach Drives Epigenetic Fixation of Foxp3 Expression and Stabilizes Treg Cell Lineage and Therapeutic Function
Immunobiology & Transplant Research Center, Houston Methodist Hospital, Houston, TX.
The instability of the regulatory T (Treg) cell lineage precludes their therapeutic potential in transplantation and autoimmune diseases. Herein, we invented a novel approach to…2018 American Transplant Congress
Endothelial Progenitor Cell-Derived Extracellular Vesicles Inhibit Kidney Ischemia-Reperfusion Injury through the Transfer of Specific microRNA and mRNA Coding for the Complement Inhibitors CD55, CD59, Factor H and for the Transcription Factor NRF2: Relevance for Delayed Kidney Graft Function
Complement activation and oxidative cell damage are hallmarks of delayed kidney graft function (DGF) due to ischemia-reperfusion injury (IRI). Endothelial progenitor cells (EPC) protect from…2018 American Transplant Congress
Galangin Promotes Treg Development and Function
Introduction: FoxP3+ Treg cells are central in controlling immune responses and transplant tolerance. CD73 (ecto-5'-nucleotidase), which serves to convert AMP to adenosine, is essential for…2018 American Transplant Congress
Rapamycin Therapy Impairs Treg Expression of CXCR3 and Limits Treg-Dependent Survival of Vascularized Composite Allotransplants
Vascularized Composite Allotransplantation (VCA) is a procedure to restore limb function or facial appearance. Rapamycin is used in efforts to preserve host Treg function and…2018 American Transplant Congress
Krüppel-Like Factor 15 is a Key Suppressor of the Glomerular Epithelial Cell Fibrosis under Centrifugal Force Driven Pressure
Hypertension is known to be responsible for a reduction in the number of functional nephrons of glomeruli due to fibrosis, which develops into a chronic…2018 American Transplant Congress
Shikonin Inhibits Th17 Development through Repressing STAT3 Activation
Background: Th17-mediated inflammatory responses are detrimental for allograft acceptance and long-term survival after transplantation. Shikonin is a naphthoquinone pigment isolated from a traditional medicinal herb…2018 American Transplant Congress
Urine Podocin mRNA to Nephrin mRNA Ratio as a Marker of "Podocyte Stress" among Kidney Allografts Losing Function
1Univ of Michigan, Ann Arbor; 2Univ of Kansas, Kansas City.
Increasing data supports the hypothesis that long term allograft loss-of-function is associated with progressive glomerulosclerosis (GS). In models of progressive GS the ratio of two…2018 American Transplant Congress
Mitochondrial Quality Control through PGC-1α in Syngenic Mouse Heart Transplant
1Anesthesiology, Duke University, Durham, NC; 2Surgery, Duke University, Durham, NC.
Intro: Impaired mitochondrial function plays a role in graft dysfunction after transplant, and recovery is facilitated by mitochondrial quality control (MQC). Two key elements of…2018 American Transplant Congress
Central Role of Mef2 Transcription Factors in Regulation of Foxp3 Expression and Treg Function
1CHOP, Philadelphia; 2UPenn, Philadelphia.
Foxp3+ Tregs express 4 class IIa Hdac enzymes (Hdac4, 5, 7 & 9) with little or no catalytic activity and yet when deleted, at least…
