A2 to B Deceased Donor Renal Transplantation Outcome Analysis: Single Center Experience
Nephrology, University of Michigan, Ann Arbor, MI
*Purpose: Initial experience under kidney allocation system (KAS) implemented in December 2014 showed equivalent outcomes for A2 to B kidney transplantation compared with ABO compatible…2021 American Transplant Congress
Development and Durability of Sars-cov-2 Antibodies Among Solid Organ Transplant Recipients
*Purpose: The response to SARS-CoV-2 may be blunted in transplant recipients, impacting reinfection risk, treatment selection, and vaccine protocols. We quantified antibody response and durability…2021 American Transplant Congress
Pharmacokinetic and Toxicity Studies of an Anti CD40L Antibody, At-1501 in Rhesus Macaques
1Novus Therapeutics, Irvine, CA, 2ALS Therapy Development Institute, Cambridge, MA
*Purpose: CD40L is a costimulatory receptor for CD40 found on T helper cells. Binding of CD40L on T cells to CD40 on antigen presenting cells…2021 American Transplant Congress
Utility of Donor-Derived Cell Free DNA for Detecting ABMR in Patients With AT1R Antibodies
*Purpose: The presence of angiotensin II type 1 receptor (AT1R) antibodies is associated with non-HLA active antibody mediated rejection (ABMR). The frequent co-existence of negative…2021 American Transplant Congress
Longitudinal Antibody Response and Viral Loads in Covid-infected Organ Transplant Recipients
*Purpose: The full spectrum of COVID-19 disease and the impact of disease severity on antibody response and viral shedding dynamics in transplant patients is unclear.…2021 American Transplant Congress
Autoimmune Responses to DNA Topoisomerase I Exacerbate Renal Allograft Injury
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Multiple clinical and pre-clinical studies describe correlations between pre-existing or de novo autoimmune responses and poor transplant outcome. We have previously reported that following…2021 American Transplant Congress
Graft Outcomes of Antibody Mediated Rejection without Donor Specific Anti – HLA Antibodies After Kidney Transplantation
Seoul National University Hospital, Seoul, Korea, Republic of
*Purpose: The aim of this study was to investigate graft outcomes based on the presence of donor-specific anti-HLA antibodies (DSA) and the time of diagnosis…2021 American Transplant Congress
COVID-19 in the Kidney Transplant Waitlist Population
1Surgery, Emory University, Atlanta, GA, 2Pathology, Emory University, Atlanta, GA
*Purpose: Through banked serum samples from transplant candidates across Georgia, we characterize the prevalence, timing, and duration of SARS-CoV-2 seropositivity and investigate the impact on…2021 American Transplant Congress
Targeting Il-21 Receptor Shifts Tfh/tfr Balance and Ameliorateschronic Antibody Mediated Rejection
Tianjin First Central Hospital, Tianjin, China
*Purpose: Donor specific antibody (DSA) plays a central role in chronic kidney allograft injury. As a trigger of humoral alloimmune response, follicular T helper cells(Tfh)…2021 American Transplant Congress
The Clinical Significance of Preformed C1q-binding Donor-specific HLA Antibodies in Kidney Transplantation
*Purpose: Complement activation is one dominant mechanism which cause allograft injury in kidney transplantation (KT). Anti-HLA donor-specific antibodies (DSA) that bind to HLA molecules on…
