Liver Kinase B1 Knockdown Induces Platelet-Derived Growth Factor Receptor B Expression in Human Airway Epithelial Cells: A Potential Mechanism for Development of Fibrosis Leading to Chronic Lung Allograft Dysfunction
St. Joseph’s Hospital and Medical Center, Phoenix, AZ
*Purpose: The platelet-derived growth factor and its receptor (PDGFRb) signaling pathway can be activated by epithelial mesenchymal transition which facilitates fibrosis. It is not known…2021 American Transplant Congress
Angiotensin II Type-1 Receptor Antibodies are Associated with Inferior Renal Allograft Survival
Renal Department, Imperial College Healthcare NHS Trust, London, United Kingdom
*Purpose: AT1R-antibodies have been implicated in antibody-mediated vascular rejection in the absence of detectable HLA donor specific antibody (DSA), in addition to cardiovascular diseases. Transplant…2021 American Transplant Congress
Late Subclinical Rejection and Borderline Rejection in Kidney Transplant Patients is Associated with Increased Incidence of Subsequent Clinical Rejections
*Purpose: The outcomes of inflammatory changes noted in late surveillance biopsies (1 year) is unclear.*Methods: Patients transplanted (live donor and deceased donor) at our center…2021 American Transplant Congress
Investigating the HLA Alloimmune Background of the Histological Changes Suggestive of Antibody-mediated Injury in the Absence of Donor-specific Anti-HLA Antibodies
Microbiology, Immunology and Transplantation, KU Leuven, Leuven, Belgium
*Purpose: The histology of antibody-mediated rejection is observed frequently after kidney transplantation, but a significant percentage of the patients do not have detectable donor-specific HLA…2021 American Transplant Congress
The Microenvironment of Belatacept-Resistant Rejection
Surgery, Emory University, Atlanta, GA
*Purpose: Belatacept is a co-stimulation blockade immunosuppressant, that despite demonstrating improved long-term outcomes, has not been widely adopted, in part, due to concern over early…2021 American Transplant Congress
Urinary Exosome Mrna Signature for the Diagnosis of Human Kidney Transplant Rejection
*Purpose: Traditional biomarkers currently used to monitor the kidney allograft, such as creatinine and proteinuria, are late markers of injury and lack sensitivity, specificity and…2021 American Transplant Congress
Impact of Donor and Recipient Age Difference: Outcomes within the First Year of Orthotopic Heart Transplant
Baylor St. Luke's Medical Center, Houston, TX
*Purpose: In recent history, the number of patients listed as eligible to receive a heart transplant has increased by nearly 40%. However, not all hearts…2021 American Transplant Congress
Obesity Impacts Acute Rejection but Not Allograft Function Improvement in the Setting of Belatacept Conversion
University of Illinois at Chicago, Chicago, IL
*Purpose: There is limited data regarding belatacept conversion in obese patients as an alternative to calcineurin inhibitor (CNI) immunosuppression. Pharmacokinetic (PK) data suggests increasing clearance…2021 American Transplant Congress
Membrane versus Centrifuge‑Based Therapeutic Plasma Exchange to Treat Antibody-Mediated Rejection in Kidney Transplantation
*Purpose: Therapeutic plasma exchange (TPE) is either performed using a highly permeable filter with standard multifunctional renal replacement equipment (mTPE) or a centrifugation device (cTPE).…2021 American Transplant Congress
Pilot Evaluation of Prognosis After Liver Transplantation in Patients with a History of Hepatocellular Carcinoma and Pd-1 Inhibition
*Purpose: The successful applications of programmed death protein-1 (PD-1) inhibitors in cancer therapy has led to an expanding use of immunotherapy in oncolog Liver transplantation…
