Protocol Donor Specific Antibody Monitoring After Kidney Transplantation: What Is the Utility?
De novo DSA has been shown to be a negative predictor of graft outcomes. However, the utility of routine DSA monitoring in the overall kidney…2015 American Transplant Congress
Detection of Donor-Specific Anti-HLA Antibodies Is Associated With Changes in the Peripheral Distribution of NK Cell Subsets in Kidney Allograft Recipients
Background: Microvascular damage has become the real protagonist involved in antibody-mediated rejection and NK-cell antibody-dependent cell mediated cytotoxicity (ADCC) has been proposed as a contributing…2015 American Transplant Congress
Antibody-Mediated Rejection of Renal Allografts by CCR5-/- Mice Does Not Require CD8 T Cells
Antibody-mediated acute and chronic graft injury remains a major cause of renal allograft loss. Mechanisms underlying these injuries remain unclear due in part to the…2015 American Transplant Congress
T Cell C5a Receptor (C5aR) Signaling Regulates T Follicular Helper Cell (Tfh) Induction
Translational Transplant Research Center, Icahn School of Medicine at Mount Sinai, New York, NY.
Tfh cells, in part via IL-6 dependent production of IL-21, are specialized providers of B cell help. Extending previous work in which we showed that…2015 American Transplant Congress
Microcirculation Inflammation in Early Surveillance Renal Biopsy in Sensitized Patients Did Not Correlate With Graft Outcome
1Renal Transplant Unit, HC - FMUSP, S Paulo, SP, Brazil; 2Lab de HLA, InCor, S Paulo, SP, Brazil.
Introduction: Microcirculation inflammation (MI) at 3-month renal biopsies and preformed donor-specific antibodies (DSA) are considered predictors of bad outcome in sensitized patients. Earlier biopsies and…2015 American Transplant Congress
Pre-Transplant Levels of TFH cell-Inducing Pro-Inflammatory Cytokines Correlate With DSA Formation After Kidney Transplantation
Donor-specific anti-HLA antibodies (DSA) represent an important biomarker for acute rejection and are a major cause of long-term graft failure after kidney transplantation (KTx). The…2015 American Transplant Congress
Desensitization With Costimulation Blockade and Proteasome Inhibition in a Non-Human Primate Model of Kidney Transplantation
[Background] Sensitization is a growing problem on the kidney waiting list. Alloantibody can significantly deteriorate graft survival. Currently used desensitization strategies are time-consuming, expensive and…2015 American Transplant Congress
In Vitro Evidence That CTLA4Ig Attenuates Recall Alloantibody Responses
Background: CTLA4Ig is an agonist that blocks CD28-B7 costimulation, downregulating T cell immunity, but also appears to negate T cell-dependent B cell activation, thus inhibiting…2015 American Transplant Congress
NK-Cell Subset Distribution, Renal Function and Biopsy Findings in Kidney Transplant Recipients With HLA Donor-Specific Antibodies
Background: Detection of post-transplant donor-specific anti-HLA antibodies(DSA) constitutes a risk factor for kidney transplant (KT) loss. NK-cell antibody-dependent cell mediated cytotoxicity(ADCC) has been proposed to…2015 American Transplant Congress
Endosome-Based Activation of Non-Canonical NF-kB Signaling By Membrane Attack Complexes
Using sera from transplant patients with high-titer panel reactive antibody (PRA), we previously described a model for studying the effects of alloantibody binding and complement…
