Identification of a Unique and Mechanistic Urinary Cell mRNA Signature in Tolerant Kidney Transplant Recipients Conditioned with FCR001 Facilitating Cells
*Purpose: Urinary cell mRNA profiling is a powerful tool to interrogate kidney allograft status and can diagnose and anticipate acute rejection in kidney allograft recipients.…2022 American Transplant Congress
Nonadherence Post-Kidney Transplant is Associated with Increased Immune Activation Detected by Peripheral Blood Gene Expression Assay
*Purpose: Nonadherence to immunosuppressive medications is common post-transplantation. We hypothesized that nonadherence results in a heightened alloimmune response in kidney transplant recipients (KTRs), which may…2022 American Transplant Congress
Single Nuclei RNA-Sequencing Identifies Distinct Cell Profile in Kidney Allografts with Recurrent Focal Segmental Glomerular Sclerosis (FSGS)
1NWU, Chicago, IL, 2University of Maryland, Baltimore, MD, 3UTHSC, Memphis, TN
*Purpose: Strong evidence suggests that primary FSGS is due to a plasma factor that results in general podocyte dysfunction and risk of recurrence after kidney…2022 American Transplant Congress
Tacrolimus Metabolizer Heterogeneity within Caucasian Kidney Transplant (KT) Recipients
1Intermountain Medical Center, Murray, UT, 2CareDX, South San Francisco, CA
*Purpose: Weight-based tacrolimus (T) dosing is the standard in post-transplant KT. African-Americans and Caucasians differ in their metabolizer phenotype for T. However, two morphometrically similar…2022 American Transplant Congress
Characterization of Hepatocytes During Cold Static Preservation at Single Cell Resolution
*Purpose: Hepatocytes together with liver sinusoidal endothelial cells (LSEC) are the most affected cells during cold preservation of donor liver. Necrotic and apoptotic hepatocytes release…2022 American Transplant Congress
Association of Trugraf GEP with Clinical and Histological Outcomes in a Multicenter Cohort (TOGETHER Study)
*Purpose: The purpose of this study was to validate the association of TruGraf GEP with clinical endpoints in a real-world cohort.*Methods: This was a multicenter…2022 American Transplant Congress
Impact of Cytomegalovirus Infection on mRNA Expression Utilizing the Molecular Microscope in Heart Transplant Recipients
Cardiology, Baylor University Medical Center, Dallas, TX
*Purpose: Little is known about the effect of CMV infection on transplant messenger RNA expression utilizing the molecular microscope (MMDx) in the absence of acute…2022 American Transplant Congress
Pretransplant Transcriptome Predicts 24-Month Kidney Function
*Purpose: With the development of novel prognostic tools derived from omics technologies, transplant medicine is entering the era of precision medicine, however, there are no…2022 American Transplant Congress
Rejection After Liver Transplantation: What Can We Learn from Transcriptomic Analysis?
1University of California, San Francisco, San Francisco, CA, 2UCLA, Los Angeles, CA
*Purpose: Acute cellular rejection (ACR) can occur at any time following liver transplantation (LT); initial ACR within 6 months is most common and occurs in…2022 American Transplant Congress
TCMR in Late Kidney Transplant Biopsies Shows Less Molecular TCMR Activity and More Fibrosis Despite Persistence of Tubulitis and Interstitial Infiltrate
1Alberta Transplant Applied Genomics Centre, Edmonton AB, AB, Canada, 2., ., AB, Canada
*Purpose: We studied the relationship between time post-transplant and molecular T cell-mediated rejection (TCMR) activity in a population of indication kidney transplant biopsies.*Methods: Updated rejection-based…
