Variable Glycosylations of Anti-HLA Antibodies Detected with Single Antigen Beads in Kidney Transplant Recipients
*Purpose: Differential glycosylation of Immunoglobulin G (IgG) is known to affect its effector functions by modulating interactions with its binding partners, such as C1q or…2019 American Transplant Congress
Anti-Donor M H C Class I I Alloantibody Induce Glomerular Injury in Mouse Renal Allografts Subjected to Prolonged Cold Ischemia
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Prolonged cold ischemia storage (CIS) of donor transplants is a major risk factor for acute and chronic graft tissue injury.The goal of this study…2019 American Transplant Congress
IgG Glycosylation Causes Podocyte Injury in Transplant Glomerulopathy through Calcium Calmodulin Kinase IV
Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA
*Purpose: Transplant glomerulopathy(TG) is a major cause of late allograft loss. Increase in urine podocin/creatinine ratio in TG signifies acceleration of podocyte detachment from glomerular…2019 American Transplant Congress
Characterization of HLA Antibodies by C3d Assay and IgG Subclasses in Sensitized Kidney Transplant Patients
Instituto Nacional de Ciencias Medicas y Nutricion SZ, Mexico City, Mexico
*Purpose: To determine the detection rate of IgG subclasses (IgGsc) and C3d-binding HLA-antibodies (abs) in a cohort of highly sensitized kidney transplant patients.*Methods: We evaluated,…2018 American Transplant Congress
Class II Anti-HLA IgG2 and IgG3 DSAs Predict Poorer Outcomes in Chronic Antibody Mediated Rejection of Renal Allografts
Introduction: whilst the development of IgG3 and C1q binding de novo [dn] HLA DSAs are associated with a poor outcome in acute antibody mediated rejection,…2018 American Transplant Congress
Identification of T Cells as Target of Intervention to Decrease Anti-LG3 Autoantibody Levels Prior to Transplantation
Research Centre, Centre Hospitalier de l'Université de Montréal (CRCHUM), Montreal, QC, Canada.
Autoantibodies against perlecan/LG3 fragment (anti-LG3) have been associated with accelerated allograft rejection and long-term renal allograft dysfunction. Intriguingly, anti-LG3 are present prior to transplantation in…2018 American Transplant Congress
Two Trajectories of Post-DSA eGFR after Kidney Transplant
A clearer understanding of the patterns of glomerular filtration rate (GFR) decline following donor-specific antibody (DSA) development and the factors that might be associated with…2018 American Transplant Congress
Follow Up of Patients Treated with the IgG Endopeptidase (IdeS) for Desensitization and HLA Incompatible (HLAi) Kidney Transplantation
Introduction:Donor-specific antibodies (DSAs) create an immunologic barrier to transplantation. This prevents transplantation for a significant percentage of highly-HLA sensitized patients (HS). Current desensitization therapies are…2018 American Transplant Congress
Role of Calcium/Calmodulin Kinase IV on Podocyte Function in Transplant Glomerulopathy
Beth Israel Deaconess Medical Center, Boston.
Background : Transplant glomerulopathy(TG) a histological manifestation of chronic antibody mediated rejection and a major cause of late allograft loss. It is well accepted that…2018 American Transplant Congress
IgG De Novo HLA Antibody Subclass Analysis in Patients Undergoing Allograft Nephrectomy after Transplant Failure
Introduction: different immunising events can stimulate the production of disparate antibody subclass profiles, reflecting a diverse extent of T-cell activation. Transplant nephrectomy (NX) is a…
