Carfilzomib and Belatacept Reduces DSA and Prolongs Survival in a Highly Sensitized Rhesus Model of Kidney Transplantation
Duke Transplant Center, Duke University Medical Center, Durham, NC.
Purpose:Sensitized kidney transplant (KT) recipients have poor access to transplantation and inferior outcomes when transplanted. Conventional methods of desensitization remove donor specific antibody (DSA) temporarily,…2018 American Transplant Congress
Ultra Low Dose of IL-2 Produces Long-Term Drug-Free Survival of Cynomolgus Islets Allografts
1Medicine and Surgery, Beth Israel Deaconess Medical Center, Boston, MA; 2Surgery, MGH, Boston, MA.
Therapeutic principles established in non-human transplant models have value for clinical application despite cost related limitations on sample size. We have tested new therapies in…2018 American Transplant Congress
Combination Proteasome Inhibition and Anti-BAFF Therapy Permits Highly Sensitized Rhesus Kidney Transplantation
Duke Transplant Center, Duke University Medical Center, Durham, NC.
Purpose:HLA-sensitization is a significant immunologic barrier to successful kidney transplantation (KT). We have shown that proteasome inhibition (PI) in insolation reduces plasma cells (PCs), but…2018 American Transplant Congress
Mechanisms of Vascularized Bone Marrow Graft Protection of Vascularized Composite Allografts
Surgery, University of Maryland, Baltimore, MD.
Background Co-transplantation of vascularized bone marrow (VBM) promotes vascularized composite allograft (VCA) survival with standard immunosuppression in a non-human primate (NHP) model. We investigated mechanisms…2018 American Transplant Congress
Targeted Donor Complement Blockade after Brain-Death Prevents Delayed Graft Function but Not Progression to Antibody-Mediated Rejection in a Non-Human Primate Model of Kidney Allo-Transplantation
1Surgery, University of Wisconsin-Madison, Madison, WI; 2Pharming Group N.V, Leiden, Netherlands.
Introduction: Donor brain death (BD) triggers a complement-mediated inflammatory response linked to renal injury which has been associated to delayed graft function (DGF) and the…2018 American Transplant Congress
Preemptive B Cell Depletion Modulates Pathogenic Alloimmunity Associated with Selective Non-Activating CD28 Blockade
Purpose: Because anti-donor alloantibody (alloAb) elaboration is associated with chronic allograft rejection, peri-transplant B cell depletion is being explored to modulate pathogenic alloimmunity. Here, we…2017 American Transplant Congress
Timing of Mesenchymal Stem Cell Infusions Affects Rejection Free and Overall Islet Allograft Survival.
We recently demonstrated that autologous, bone marrow-derived mesenchymal stem cells (MSC) promote allogeneic islet engraftment and survival in a streptozotocin induced, cynomolgus monkey model of…2017 American Transplant Congress
mRNA Biomarkers in Renal Allograft Protocol Biopsies Detected by the Nanostring Platform Predict Tolerance in Non-Human Primates.
Background. Renal allograft tolerance has been achieved in some but not all MHC mismatched kidneys in non-human primates (NHPs) and humans after induction of transient…2017 American Transplant Congress
D-Dimer Level, in Association with Humoral Responses, Negatively Correlates with Survival of Porcine Islet Grafts in Nonhuman Primates with Immunosuppression.
Background: Several immunosuppression (IS) regimens achieve long-term graft survival in nonhuman primates (NHPs) after porcine islet transplantation (PITx), but their success rates vary. To understand…2017 American Transplant Congress
Lymphoid Isolation as an Adjuvant Maneuver for Belatacept-Based Immunotherapy.
Purpose: Belatacept targets de novo alloimmune responses with minimal off target effects in renal transplantation, though adjuvant therapy is required for control of costimulation-blockade resistant…
