Significant Allosensitisation Despite Early, within 24 Hour, Graft Nephrectomy.
Introduction: Although it is well known that allograft nephrectomy (Nx) is followed by the development of donor-specific antibodies (DSAs) even after a short transplant period,…2017 American Transplant Congress
Strategy for Analysis of Donor-Specific Antibody Repertoire: Paired Immunoglobulin Heavy and Light Chain Analysis of Individual Memory B Cells.
Antibody-mediated rejection (ABMR) is the most challenging immunological barrier to overcome in human transplantation and one of the most prevalent causes of kidney allograft loss.…2017 American Transplant Congress
Assessment of Cardiosphere-Derived Cell Exosomes as Possible Modulator of Alloimmunity in a Mouse Model of HLA-A2 Allosensitization.
Purpose: Mounting data indicate that exosomes, a nanosized membrane particle secreted by cells has immune regulatory properties, including anti-inflammation and mediating autocrine, paracrine, and endocrine…2017 American Transplant Congress
Development of an Anti-HLA Antibody-Producing Humanized Mouse Model.
Chronic antibody-mediated rejection due to anti-human leukocyte antigen (HLA) antibodies (Abs) is an important problem in organ transplantation. The spleen has been reported to be…2017 American Transplant Congress
Graft Survival in De Novo Donor-Specific Antibodies and Positive Flow Crossmatch Kidney Transplants Is influenced by Class I and Class II.
Patients with de novo donor-specific antibodies (dnDSA) show inferior graft survival in numerous small studies. We assessed the effect of dnDSA on graft and patient…2017 American Transplant Congress
Generation of Natural Antibodies Post Transplant and Association with Kidney Allograft Loss.
The development of donor specific antibodies (DSA) reacting to mismatched donor class I and class II HLA is a prominent risk factor for kidney graft…2017 American Transplant Congress
Prospective Monitoring of De Novo Donor-Specific Antibodies: Incidence, Clinical Outcomes and Dynamic Changes Over 5 Years After Kidney Transplantation.
Montefiore Medical Center Transplant Center, Albert Einstein College of Medicine, Bronx
Background: We aimed to investigate the incidence and dynamic changes of de novo donor-specific-antibodies (dnDSA) after kidney transplantation and clinical outcomes.Methods: This is a prospective…2017 American Transplant Congress
Prevention of Donor Specific Antibody Production After Skin Allografting by Mobilization of Endogenous Stem Cells Using a Combination of AMD3100 and Low-Dose FK506 in Rats.
Background: We have developed a stem cell mobilizing strategy that enables long-term liver and kidney allograft survival without sustained immunosuppression in small and large animals…2016 American Transplant Congress
Comparison of C4d Deposition in Renal Biopsies with Luminex-Based C3d Single Antigen Bead (SAB) Detection.
Recent interest in characterizing the complement-fixing ability of post-transplant donor specific alloantibodies (DSA) resulted in the enhancement of luminex solid phase alloantibody assays to determine…2016 American Transplant Congress
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.…
