Gene Expression Profiles of Peritubular Capillarits in Chronic Antibody-Mediated Rejection
*Purpose: Antibody-mediated rejection (ABMR) is one of the most significant contributors to late graft loss. Hallmark characteristics include peritubular capillaritis (ptc) and glomerulitis (g). Diffuse…2022 American Transplant Congress
A Signature of Tolerance Which Identifies Subclinical Rejection-Free Patients at One Year After Kidney Transplantation
*Purpose: Spontaneous and rare cases of patients undergoing a functional renal transplant in the absence of immunosuppression represent a particular situation of immune tolerance. We…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
Establishment And Validation Of A Predictive Model For Differential Rejection Diagnosis By Gene Expression Profiling (GEP) In Renal Allograft Biopsies Using Banff Human Organ Transplant (B-HOT) Gene Panel
1CareDx, Inc., Brisbane, CA, 2Arkana Laboratories, Little Rock, AR
*Purpose: Large scale GEP studies evaluating the performance of Banff-endorsed B-HOT gene panel for allograft rejection diagnosis have not been published. In this study, we…2022 American Transplant Congress
Protein and Transcriptomic Differences Between High and Low Neointimal Arteries in Human Cardiac Allograft Vasculopathy Rejected Grafts
*Purpose: Cardiac allograft vasculopathy (CAV) is the leading cause of graft failure and mortality following heart transplantation. Donor specific antibodies (DSA) contribute to CAV progression…2022 American Transplant Congress
Crosstalk Between micro-RNAs, mRNAs, and Long Non-Coding RNAs in Human Hepatic Ischemia Reperfusion Injury
*Purpose: Present study utilizes multiple omics tools and clinical samples with a system biology approach characterizing mRNAs, long non-coding RNAs (lncRNAs) and small non-coding RNAs…2022 American Transplant Congress
Evaluating Long Term Outcomes in Kidney Transplant Patients with TruGraf Gene Expression and TRAC Dd-cfdna in the TRULO Study
Eurofins Transplant Genomics, Framingham, MA
*Purpose: The aim of this study is to evaluate long term clinical outcomes in kidney transplant patients undergoing non-invasive rejection monitoring with the OmniGraf® biomarker…2021 American Transplant Congress
VP2 MRNA Distinguishes the Direct Injury and Inflammation Effects of Polyoma Virus (BK) Infection from the Cognate TCMR Response That Follows Immunosuppressive Minimization
*Purpose: BK virus nephropathy (BKN) and T cell-mediated rejection (TCMR) are difficult to distinguish by histology but often coexist due to the necessity for immunosuppression…2021 American Transplant Congress
RNA Sequencing (RNAseq) Tissue Analysis Can Provide Early Warning Signals for Potential Intestinal Transplant Complications
*Purpose: A disrupted mucosal barrier in intestinal grafts can cause alloreactive complications such as rejection, inflammation and infection following intestinal transplantation (ITx). We hypothesize that…2021 American Transplant Congress
Transcriptomics and Proteomics Profiling of Complement Pathway (cp) Proteins in Biopsies With Polyomavirus Bk Nephropathy (bkvn)
*Purpose: Late stage BKVN can show C4d as well as classic immune complex deposits in the tubular basement membranes (Bracamonte et al. Am J Transplant…
