Molecular Associations in Kidney Transplant Biopsies in the Trifecta Study Indicate That at Least Three Distinct Processes Release Dd-cfDNA: ABMR, TCMR, and Injury
*Purpose: In the Trifecta study (ClinicalTrials.gov # NCT04239703 53), elevated plasma dd-cfDNA is associated with molecular rejection in kidney transplant indication biopsies, particularly active ABMR…2022 American Transplant Congress
Upregulation of Innate Immune Pathways is Associated with Increased Rejection in HIV-Infected Kidney Transplant Recipients
1UC San Francisco, San Francisco, CA, 2CA
*Purpose: Although kidney transplantation (KT) has become the standard of care for HIV+ patients with renal failure, early experiences revealed high acute rejection (AR) rates.…2022 American Transplant Congress
Flow Cytometric Pattern of γδ Tcr Expression Identifies Outcomes in Kidney Transplantation
*Purpose: The main challenge with kidney transplantation is the possibility of rejection, classified into two types, antibody-mediated rejection (ABMR) and T cell-mediated rejection (TCMR). The…2022 American Transplant Congress
Evaluation of Genotype Based Clustering Method of Single-Cell RNA-Sequencing Data from Human Kidney Allograft Biopsies
1Weill Cornell Medicine, Doha, Qatar, 2Weill Cornell Medicine, New York, NY
*Purpose: Single-cell RNA sequencing (scRNA-seq) characterizes expression profiles of individual cells, providing novel insights into new cell types or new cell states that were not…2022 American Transplant Congress
Development of a Dynamic Map of Peripheral Myeloid Cells Associated with Acute Rejection of Vascularized Composite Tissue Allografts
*Purpose: Myeloid cells are involved in early alloactivation in response to organ allografts and can initiate acute rejection. The heterogeneity of myeloid populations and the…2022 American Transplant Congress
Strada Deficiency Results in Inhibition of Tumor Suppressor Gene Liver Kinase B1 Resulting in Epithelial Mesenchymal Transition Leading to Chronic Murine Lung Allograft Rejection
St. Joseph’s Hospital and Medical Center, Phoenix, AZ
*Purpose: Recently we demonstrated that tumor suppressor gene Liver Kinase B1 (LKB1) is down regulated in lung biopsies and in the circulating exosomes of lung…2022 American Transplant Congress
Ficoll-Based Isolation Alters the Immunogenicity of Islets That Leads to Enhanced Rejection in Allogeneic Hosts
*Purpose: The purification of pancreatic islets has long relied on the time-consuming density gradient separation method. We herein report a filtration method as an efficient,…2022 American Transplant Congress
Comparative Analysis of kSORT Assay for Predicting Acute Renal Allograft Rejection Under Belatacept-Based Immunosuppression
*Purpose: The kSORT (Kidney Solid Organ Response Test) assay uses transcriptomic profiling of peripheral blood to predict the presence of acute rejection (AR) in renal…2022 American Transplant Congress
Technology-Driven Performance Improvement of a Biomarker Panel in Kidney Transplant: OmniGraf
*Purpose: Analyze the impact of the transition from TruGraf microarray to TruGraf PCR on the complementary performance characteristics of TruGraf plus TRAC (OmniGraf).*Methods: Development of…2022 American Transplant Congress
Recipient Neutrophil Production of Myeloperoxidase is Required for NK Cell Activation During Acute Antibody Mediated Allograft Rejection
*Purpose: Dysregulated donor-specific antibody (DSA) responses are induced in B6.CCR5-/- mice transplanted with complete MHC mismatched A/J kidney allografts and are required for rejection of…
