*Purpose: Laminin α5 (Lama5) and α4 (Lama4) are lymph node (LN) stromal fibers whose expression ratio influences CD4+ T cell migration and stimulation. We hypothesized…2020 American Transplant Congress
DEPTOR Expression within CD4+Foxp3+ T Regulatory Cells is Crucial for B Cell Activation Responses and Immunoregulation
1Boston Children's Hospital, Boston, MA, 2Lavel University, Quebec, QC, Canada
*Purpose: We have previously reported that the intracellular protein DEPTOR stabilizes Foxp3 expression, enhances suppressive Treg function and inhibits Treg dedifferentiation. Overexpression of DEPTOR within…2020 American Transplant Congress
CD137 Signaling in Regulatory Dendritic Cells Is Required for Suppressing a Systemic Inflammation in the bm12-Inducible Model of Systemic Lupus Erythematosus
*Purpose: Although CD137 is well known as a costimulatory receptor in T cells, limited information is available for its immunoregulatory function. Here, we report that…2020 American Transplant Congress
Factors Influencing Background Cell-Free DNA Levels: Implications for Donor-Derived Cell-Free DNA Assessment in Transplant Patients
*Purpose: Detecting elevated levels of donor-derived cell-free DNA (dd-cfDNA) in the plasma of transplant recipients has been used as a metric to determine graft injury…2020 American Transplant Congress
Trends in Living Kidney Donation in the United States
Johns Hopkins University, Baltimore, MD
*Purpose: After peaking in 2014, the number of LKDTs per year dropped substantially in the US despite an increasing waitlist. However, trends in the KAS…2020 American Transplant Congress
Single Cell RNA Sequencing of Normal Kidney Allograft Surveillance Biopsies Show Evidence of Dynamic Glomerular Endothelial Cell Activation
University of Michigan, Ann Arbor, MI
*Purpose: Indication and surveillance biopsy studies show a high prevalence of post kidney transplant (KT) glomerular disease (ElZoghby 2009,Stegall 2017) that cannot be explained by…2020 American Transplant Congress
Evaluation of Infectious and Malignant Complications in Elderly Renal Transplant Recipients Receiving Alemtuzumab Compared to Basiliximab
*Purpose: The choice of induction immunosuppression can affect several outcomes after kidney transplant (KTx), especially for elderly recipients. For this population, there is limited data…2020 American Transplant Congress
The Banff Classification of Antibody-Mediated Rejection in Kidney Allografts: Comparison of Predictive Performance for Allograft Failure in Previous and Current Editions
*Purpose: Since its introduction in 2001, the Banff classification for antibody-mediated rejection (ABMR) has undergone significant changes, mainly by inclusion of C4d-negative ABMR in 2013…2020 American Transplant Congress
Transplant Surgery Continuing Professional Development Courses Increase Knowledge and Procedural Confidence
*Purpose: Continuing professional development (CPD) workshops are emerging to fill critical knowledge and skill gaps in both surgical trainees and practicing surgeons. The ASTS has…2020 American Transplant Congress
Safety and Patency of Inferior Vena Cava Reconstruction with Artificial or Autologous Blood Vessels During Liver Autotransplantation: Five-Year Results from a Prospective Cohort Study of 73 Cases
*Purpose: To compare the short-term and long-term effects of artificial blood vessels and autologous blood vessels to reconstruct the retrohepatic inferior vena cava (IVC) in…
