Circulating Exosomes with Cardiac Self-Antigens, Myosin and Vimentin, Induced Immune Responses Leading to Rejection Following Heterotopic Cardiac Transplantation Immunosuppressed with mTOR Inhibitor and Low Dose of IL-2 Therapy
Norton Thoracic Institute, St. Joseph’s Hospital and Medical Center, Phoenix, AZ
*Purpose: The aim of the study is to determine the role for circulating exosomes with cardiac self-antigens (SAgs) (Myosin, Vimentin) in the development of immune…2020 American Transplant Congress
Pre-Transplant Detection of Anti-at1r Antibodies and Pediatric Kidney Transplantation Outcomes
1UT Health San Antonio, San Antonio, TX, 2University Health System, San Antonio, TX
*Purpose: Describe correlations between pre-transplant (PreTXP) presence of anti-angiotensin II receptor type 1 antibodies (AT1R Ab) and post-transplant (PostTXP) outcomes in a pediatric kidney transplant…2020 American Transplant Congress
Morbidity in Lung Transplant for Connective Tissue Disease
*Purpose: To evaluate the post-lung transplant comorbidities of patients with connective tissue disease (CTD) compared with an age-matched cohort of patients transplanted for idiopathic pulmonary…2020 American Transplant Congress
Rare Genetic Mutation Triggering Acute Liver Failure in a Toddler Needing a Liver Transplant
1Cleveland Clinic, Cleveland, OH, 2Akron Children's Hospital, Akron, OH
*Purpose: The AIRE gene plays an important role in immune tolerance by driving negative selection of self-recognizing T-cells. Mutations in this gene are responsible for…2020 American Transplant Congress
Immune Response Following Cardiac Progenitor Cells Transplantation in Rat Myocardial Infarction Model
Surgery, University of Maryland, Baltimore, MD
*Purpose: Cardiac progenitor cells (CPCs, c-kit+) are well-characterized stem cell type shown to potentiate cardiac regeneration in myocardial infarct (MI) model. However, auto and allo…2020 American Transplant Congress
Natural Antibodies and Left Ventricular Assist Device Complications
*Purpose: Left ventricular assist device (LVAD) implantation is followed by a sharp increase in serum levels of IgG natural antibodies (Nabs) recognizing oxidation-specific epitopes (OSE)…2020 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 de novo autoimmune responses and poor transplant outcome. We have previously reported that following renal transplantation,…2020 American Transplant Congress
Profiling Non-HLA Antibodies in Antibody-Mediated Rejection Following Cardiac Transplantation
*Purpose: Antibody-mediated rejection (AMR) driven by the development of donor-specific antibodies (DSA) directed against mismatched donor HLA is a major risk factor for graft loss…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
Angiotensin II Type 1 Receptor Antibodies are Associated with Younger Age and Renal Dysfunction in Pediatric Kidney Transplantation
1UCLA, Los Angeles, CA, 2Duke, Durham, NC, 3Emory, Atlanta, GA, 4Stanford, Stanford, CA
*Purpose: The significance of non-HLA antibodies in renal transplantation remains unclear. In small single center retrospective studies, angiotensin II type 1 receptor antibody (AT1R-Ab) has…
