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…2017 American Transplant Congress
Vital Role of the CoREST Complex as a Master Regulator of Foxp3+ T-Regulatory Cell Gene Expression and Suppressive Function.
While the Foxp3 promoter and its three associated conserved non-coding sequence (CNS)/enhancer regions have received much attention, literally nothing is known of the contribution of…2017 American Transplant Congress
Transcriptome Analysis of CD4-Lymphocyte Specifically Deleted of IKKbeta or NEMO in an Experimental Model of Rapid Progressive Glomerulonephritis (RPGN).
RPGN is T-cell mediated and can recur after kidney transplantation. T-cell receptor stimulation leads to intracellular signaling events ultimately causing activation of transcription factors such…2017 American Transplant Congress
High CTLA-4 Expression and Diminished FOXO3 Expression Underlie Differential CD28 Signaling on Human Memory Th17 Cells.
Pathogen primed memory T cells can cross-react with allogeneic antigen and mediate graft rejection, a process termed allogeneic heterologous immunity. Th17 cells are pro-inflammatory CD4+…2016 American Transplant Congress
Liver Graft Rejuvenation Prior to Transplantation: A Bench-to-Bedside Approach.
1Surgery, Dumont-UCLA Translant Center, Los Angeles, CA; 2Pathology, UCLA, Los Angeles, CA.
To address the shortage of organs for transplantation many use “marginal” livers, which are particularly susceptible to ischemia-reperfusion injury (IRI). We have taken a two-pronged…2016 American Transplant Congress
Hydrogen Sulphide Is an Important Regulator of Erythropoietin Synthesis in Patients with Anemia of Chronic Kidney Disease.
Anemia affects 90% of hemodialysis patients and is a tremendous concern for patients and health care providers. CKD leads to chronic interstitial fibrosis which leads…2016 American Transplant Congress
IL-17-Producing CCR6+CD4+ Th17 Cells Drive Intestinal Allograft Rejection in Humans.
MedStar Georgetown Transplant Institute, Washington DC.
A. Allograft rejection remains a significant source of mortality and morbidity in intestinal transplant (ITx) recipients. However, the underlying mechanisms remain unclear. The purpose of…2016 American Transplant Congress
T-Bet Regulates nTreg Stability and Suppression in an Islet Allograft Model.
University of Maryland, Baltimore.
The transcription factor T-bet endows Treg with properties tosuppress Th1 inflammation. However, the mechanisms by which T-bet controls alloimmune responses are not fully understood. We…2015 American Transplant Congress
Th-17 Alloimune Responses in Renal Allograft Biopsies from Recipients of Kidney Transplants Using Extended Criteria Donors During Acute T-Cell Mediated Rejection
Although renal transplantation using expanded criteria donors has become a common practice, immune responses related to immunosenescence in those kidney allografts have not been studied…2015 American Transplant Congress
Pro-Inflammatory Actions of New Non-HLA Antibodies Targeting Protease-Activated Receptor (PAR-1)
Microvascular endothelium is major target for antibodies directed against HLA and non-HLA antigens. Functional antibodies targeting G-protein coupled receptors (GPCRs) such as AT1R or ETAR…
