Intravenous Immunoglobulins Failed to Prevent Acute Antibody-Mediated Rejection in Kidney Transplant Recipients with De Novo DSA within the First Year After Transplant.
BackgroundAround 25% of kidney transplant recipients develop de novo anti-HLA donor specific antibodies (DSA). Most of them are detected within the first year after transplant.…2016 American Transplant Congress
RNAseq Transcriptome Analysis of Bone Marrow CD138+ Plasma Cell Responses to Carfilzomib Monotherapy Desensitization.
Medicine, Surgery, Biomedical Informatics, U of Cincinnati, Cincinnati Children's, Cincinnati, OH.
Purpose: Prior studies indicate that bone marrow resident plasma cells (BMRPCs) demonstrate varying sensitivity to proteasome inhibition (PI). Effects of carfilzomib (CFZ) monotherapy desensitization on…2016 American Transplant Congress
Post-Transplant Reduction of Long Lived Plasma Cells from Peripheral Circulation Is Associated with Acute Rejection in Kidney Transplant Recipients.
Introduction:Plasma cells (PC) are usually defined functionally as antibody secreting cells (ASC). Depending upon their life span, they could either be short lived or long…2016 American Transplant Congress
NK Cells Are Required in B-Cell Dependent, Antibody Mediated Islet Transplant Tolerance.
Dept of Surgery, Transplant Surgery Division, Massachusetts General Hospital, Boston, MA.
Immunologic tolerance to islets has been achieved in various rodent models using antibodies directed at CD45RB and Tim-1. We have shown that this tolerance mechanism…2016 American Transplant Congress
Transitional B Cell T1/T2 Ratio Is a Prognostic Marker for Human Renal Allograft Deterioration.
1UPMC, Pittsburgh; 2University of Leeds, Leeds, United Kingdom.
Human transitional B cells (TrB) may play a significant role in auto and alloimmune disease. TrB express a high IL10:TNFα ratio and this fell with…2016 American Transplant Congress
TGFb in Regulatory B Cells-Dependent Tolerance.
Surgery, Massachusetts General Hospital, Boston, MA.
In transplantation, increasing evidence support that B cells can play a major regulatory role in addition to their critical functions in allo-immunity and graft rejection.…2016 American Transplant Congress
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…2016 American Transplant Congress
VDJ Immune Repertoire Sequencing Predicts Patients at Risk of Alloimmune Injury.
1Surgery and Bioinformatics, UCSF, San Francisco, CA; 2Genetics, Stanford University, Palo Alto, CA.
Background: The complex repertoire of immune receptors generated by B cells enables allo-recognition in the context of transplantation across HLA barriers, and is a major…2016 American Transplant Congress
Patients Treated with Belatacept Show Low Levels of APRIL and HLA Antibodies.
Belatacept, a fusión protein that blocks the B7-CD28 costimulation pathway, decreases the level of antibodies in non-human primates and murine models but, few studies have…
