p40 Homodimers Indirectly Induce Endogenous Donor-Reactive Memory CD8 T Cell Activation within High-Risk Cardiac Allografts and CTLA-4ig Resistant Graft Rejection via IL-15 Signaling
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: We have reported that longer duration of cold ischemic storage (CIS) prior to transplant resulted in increased proliferation of endogenous donor-reactive CD8 T cells…2020 American Transplant Congress
Molecular Phenotypes of Liver Transplant Injury: The INTERLIVER Study
1Alberta Transplant Applied Genomics Centre, Edmonton, AB, Canada, 2., ., AB, Canada
*Purpose: Liver parenchymal injury phenotypes are difficult to evaluate by histology but could be amenable to molecular assessment. Having developed a Molecular Microscope® Diagnostic System…2020 American Transplant Congress
Improving DRG Based Reimbursement to Reflect Complexity of Kidney Transplant
*Purpose: More than 90,000 individuals await a kidney transplant (KTx) in the US, yet up to 20% of recovered kidneys are discarded. Organ Transplant Centers…2020 American Transplant Congress
Treg Protection of the Allograft Depends on Lymphotoxin Beta Receptor Expression in Lymphatic Endothelial Cells
1University of Maryland, Baltimore, Baltimore, MD, 2Harvard U, Boston, MA
*Purpose: Regulatory T cell (Treg) migration to afferent lymphatics and lymph nodes (LN), and suppressive function, require Treg lymphotoxin alpha (LTα) to stimulate LT beta-receptor…2020 American Transplant Congress
Additive Effect of Obesity to Hypertension in Living Donors and Their Impact on Glomerular Filtration Rate Compensation with 5 Year Follow-Up
*Purpose: Current data suggest that hypertensive donors can be considered for donation; however, the additive adverse effect of obesity and the risk of failing Glomerular…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
Allograft Repopulating Recipient B Cells after Human Intestinal Transplantation and Their Association with Donor Specific Antibody Secretion and Rejection
*Purpose: Alloantibodies produced by recipient B cells are associated with rejection after intestinal transplantation (ITx) and negatively impact patient and graft survival. However, the dynamics…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
A Multicenter, Randomized, Controlled Trial to Steer Immunosuppressive Therapy by Virus-Specific T Cells after Pediatric Kidney Transplantation (IVIST-Trial)
*Purpose: Pharmakokinetic monitoring of immunosuppressants alone is insufficient to estimate the individual intensity of immunosuppression after kidney transplantation (Tx). Virus-specific T cells (Tvis) correlate with…2020 American Transplant Congress
Flagging of Transplant Centers Associated with Increased Waitlist Mortality among Liver Candidates
University of Alabama at Birmingham, Birmingham, AL
*Purpose: Previous studies have demonstrated decreased transplant rates among poor performing transplant centers meeting Centers for Medicare & Medicaid Services (CMS) flagging criteria. However, no…
