Single Cell Phospho-Protein Analysis Demonstrates That Immunosuppressive Drugs Inhibit MAPK and mTOR Signaling Molecules in Primary Monocytes After Transplantation
Nephrology and Transplantation, Dept. of Internal Medicine, Erasmus MC, Rotterdam, Netherlands.
Monocytes have been identified as key players driving rejection processes. It is therefore surprising that there are almost no data available about the impact of…2015 American Transplant Congress
Presence of Donor Leukocytes and Donor MHC-Cross-Dressed Recipient Cells and Its Relationship to Direct T Cell Alloresponses After Allotransplantation
We have studied the kinetics of donor cell trafficking from the graft to recipient's lymphoid organs and its correlation to the direct T cell alloresponse…2015 American Transplant Congress
The 20S Proteasome Is Active in Apoptotic Nanovesicles and Controls Anti-LG3 Antibody Production
Humoral autoreactivity to apoptotic cells and perlecan/LG3, a proteoglycan fragment released by apoptotic cells, predicts poor allograft outcomes in renal transplant patients. How apoptotic cells…2015 American Transplant Congress
MHC-Class-II Specific Sensitization in a Non-Human Primate Model of Sensitzation
1Emory University, Atlanta, GA; 2Medical University Vienna, Vienna, Austria.
[Background] Sensitization before transplantation and de novo alloantibodies affect a significant number of patients awaiting kidney transplantation. The type of anti-HLA antibody varies with subgroups…2015 American Transplant Congress
Transplant Glomerulopathy in a Novel Model of Chronic Antibody Mediated Rejection Is Associated With DSA and Glomerular IgM
PurposeChronic active antibody mediated rejection (cAMR) and transplant glomerulopathy (TG) are major determinants of long-term allograft survival. However, the contribution of DSA and glomerular immunoglobulins…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
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
T-Cell Depletion Versus Interleukin-2 Antagonists in a Kidney Transplant Model of Sensitized Rhesus Macaques
[Background] Sensitized patients comprise up to a third of the kidney waiting list. Preformed and newly formed alloantibodies post transplantation (TX) deteriorate graft survival, recall…2015 American Transplant Congress
Distinct Subtypes of Rejection in a Novel Non Human Primate Model of Sensitization
[Background] Preformed and newly formed alloantibody post transplantation (TX) can significantly deteriorate graft survival. Patterns of humoral rejection in sensitized patients varies significantly due to…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…
