MHC/HLA-Specific IgE in Allotransplantation.
Background: Donor-specific antibodies (DSA) are recognized as important factors in determining outcome in renal transplantation.Typically DSAs of the IgG isotype are measured, but little is…2016 American Transplant Congress
Designing and Synthesizing a Novel Highly Selective Immunoproteasome Inhibitor That Promotes Long Term Heart Allograft Acceptance While Reducing Plasma Cells and Donor Specific Antibodies.
Antibody mediated rejection (AMR) is one of the most important barriers to improving long-term transplant outcomes. Traditional therapies for AMR do not deplete the source…2015 American Transplant Congress
Controlling Alloreactive B Cell Responses in Sensitized Recipients With CTLA-4Ig
Sensitized recipients are defined by the presence of pre-transplant donor-specific antibodies and have significantly poorer graft outcomes compared to unsensitized recipients despite efforts to desensitize.…2015 American Transplant Congress
Cardiac Xenotransplantation: Reconstituted B Cells After Rituxan Treatment Maintain Their Repertoire But Have a Muted Response to Xenoantigens
1CSRP/NIH/NHLBI, NIH, Bethesda, MD; 2DVR/ORS, NIH, Bethesda, MD; 3Revivicor Inc, Blacksburg, VA.
Background: Xentoranplantation (XTx) remains an option for end stage organ failure. Recently we have reported cardiac xenograft survival of over one year pig to baboon…2015 American Transplant Congress
The Spleen Is the Primary Site for Breg Induction and Is Required for Anti-TIM-1 Mediated Tolerance
Thomas E. Starzl Transplantation Institute, University of Pittsburgh, Pittsburgh, PA.
B cells can exhibit potent IL-10-dependent regulatory (Breg) activity. IL-10-enriched Bregs can transfer tolerance in auto and allo-immune models. We showed that TIM-1 is an…2015 American Transplant Congress
Blocking CD40/CD154 Co-Stimulation Prevents Acute Antibody-Mediated Renal Allograft Rejection Induced by Memory CD4 T Cells
Immunology, The Cleveland Clinic, Cleveland, OH.
Immunosuppression-resistant alloreactive memory CD4 T cells induce robust responses against organ transplants. In murine heart allograft recipients donor-reactive memory CD4 T cells provide help for…2015 American Transplant Congress
Hepatic Stellate Cells Directly Inhibit B Cells Via PD-L1
Hepatic stellate cells (HSCs) account for one third of the nonparenchymal cells in the liver, which are considered to be critical in maintaining the immunoprivileged…2015 American Transplant Congress
Impact of CXCR4/CXCL12 Blockade on Normal Plasma Cells In Vivo
Receptor/ligand interactions in stromal microenvironments play important roles in the localization, development and survival of normal antibody-secreting plasma cells. The goal of the current study…2015 American Transplant Congress
B Cell Depletion With an Anti-CD20 Antibody Enhances Alloreactive Memory T Cell Response After Transplantation
Pre-transplant B cell depletion in NHP with Rituximab (IgG1 anti-CD20 mAb) combined with cyclosporin A has been shown to promote the survival of islets allografts.…2015 American Transplant Congress
IgM+ Antigen Binding B Cells in Peripheral Blood Regulate IFNγ Production in Response to HLA Proteins
Chronic antibody mediated rejection (CAMR) is a major cause of graft loss in renal transplant recipients. Previous work utilising an IFNγ ELISPOT assay revealed two…
