Ectopic Lymphoid Structures Are Present in Type I T-Cell Mediated Kidney Transplant Rejection.
BackgroundIn renal transplantation, many allograft recipients develop donor-specific antibodies associated with an increased risk for graft rejection. Current immunosuppressive agents are principally aimed at T-cell-mediated…2017 American Transplant Congress
C1q+ and IgG3+ De Novo Donor Specific Antibody Are Associated with Allograft Failure in a Multicenter Cohort.
Introduction: De novo donor specific antibody (dnDSA) is a risk factor for antibody mediated rejection and allograft loss, but dnDSA does not always lead to…2017 American Transplant Congress
Biomarkers of Epithelial-Mesenchymal Transition (EMT) in Chronic Allograft Nephropathy: Potential for Early Detection and Development of Novel Therapeutic Agents.
Pathology, BioChemistry and Medical Laboratory Sciences, Rush University Medical Center, Chicago, IL
Purpose: To detect markers and novel treatment targets related to fibrogenesis and eventual graft loss by focusing on Epithelial Mesenchymal transition (EMT) which requires understanding…2017 American Transplant Congress
Clinical Correlation of Endomyocardial Biopsies Molecular Profiling: Taking Rejection Diagnosis Beyond Histology.
Histology grading of endomyocardial biopsies (EMB), the standard for diagnosing T-cell-mediated (TCMR) and antibody-mediated (ABMR) rejection, has serious issues with reproducibility (Transplantation 94 (11):1172177, 2012)…2017 American Transplant Congress
Characterization of De Novo Donor-Specific HLA Antibodies and Correlations with C4d+ Antibody-Mediated Rejection of Kidney Transplants.
Aim: Characteristics of de novo donor-specific HLA antibodies (dnDSA) that are associated with C4d positive antibody-mediated rejection (C4d+ AMR) in kidney transplants have not been…2017 American Transplant Congress
Use of Forensic DNA Testing to Trace Unethical Organ Procurement and Organ Trafficking Practices.
The purpose of this study is to establish a methodology, which allows to identify evidence of transplant organs originating from Falun Gong prisoners of conscience…2017 American Transplant Congress
The Molecular Phenotypes of Rejection in Kidney Transplant Biopsies.
University of Alberta, Edmonton, AB, Canada
In a microarray analysis of 1208 kidney transplant indication biopsies, each biopsy was assigned molecular scores for seven phenotypes related to various aspects of TCMR,…2017 American Transplant Congress
Biopsies (Bx) of Renal Allografts with Antibody- + Cell-Mediated Rejection (ABMR/CMR) Exhibit Gene Expression Signatures from Both Types of Rejection.
Background: In HLA-sensitized kidney transplant patients (Pts) the concomitant presence of ABMR/CMR on Bx is associated with a more severe and (&) usually irreversible injury…2017 American Transplant Congress
C5b-9 Deposition in Glomerular Capillaries Is Responsible for Poor Allograft Survival in Antibody-Mediated Rejection.
1University Hospital, Montpellier, France; 2Cancer Research Institute, Montpellier, France
Introduction: C4d (scare of C4 cleavage) deposition in peritubular capillaries (PTC), a marker of complement activation, is associated with antibody-mediated rejection (AMR) in kidney transplantation.…2017 American Transplant Congress
Long-Term Immunosuppression Adherence After Kidney Transplant and Relationship to Allograft Histology.
Background: Loss of Medicare coverage for immunosuppression 3 years after kidney transplant may be associated with increased nonadherence. The goal of this study was to…
