Local Intragraft Humoral Immune Response in Chronic Lung Allograft Dysfunction
*Purpose: Donor HLA-specific antibody (DSA) and antibody against self-antigens (self-antigen antibody) can cause injury and lead to chronic lung allograft dysfunction (CLAD) after lung transplantation…2022 American Transplant Congress
Allogenic Cardiac Progenitor Cells Transplantation with Immune Suppressant Cyclosporine a Recovers Myocardial Infarction in Rodent Model
Pediatrics, Lurie Childrens Hospital, Chicago, IL
*Purpose: Cardiac progenitor cells (CPCs) are well-characterized stem cell type shown to potentiate cardiac regeneration in myocardial infarct (MI) model. However, auto and allo immune…2021 American Transplant Congress
Donor Mhc-independent Islet Rejection in Autoimmune Diabetes: Implications for Stem Cell Therapy
*Purpose: Stem cell technology is an attractive approach for generating insulin-producing cells for transplantation in insulin-dependent diabetes and potentially can be genetically modified. One recent…2021 American Transplant Congress
A Phase 1 Study to Evaluate the Safety, Tolerability and Pharmacokinetics of At-1501
1Novus Therapeutics, Irvine, CA, 2ALS Therapy Development Institute, Cambridge, MA
*Purpose: Execute a phase 1 study of AT-1501 to assess safety, pharmacokinetics, and functional activity.*Methods: The study employed a placebo-controlled, sequential, dose-escalation design. 28 healthy…2021 American Transplant Congress
Autoantibodies Against Ro/SS-A, CENP-B, and La/SS-B are Increased in Patients with Kidney Allograft Antibody-mediated Rejection
*Purpose: Antibody-mediated rejection (AMR) causes >50% of late kidney graft losses. Although donor-specific antibodies (DSA) against HLA cause AMR, antibodies against non-HLA antigens are also…2021 American Transplant Congress
Transgenic Beta-cell Cxcl12 Expression and Stem Cell Mobilization Synergize to Suppress Type 1 Diabetes
*Purpose: Hematopoietic stem and progenitor cells (HSPCs) and regulatory T cells (Tregs) highly express CXCR4, the receptor for the CXCL12 chemokine. This keeps them predominantly…2021 American Transplant Congress
Recurrence and Outcome of Anti-GBM Glomerulonephritis After Kidney Transplantation: A Belgian Multicenter Study
Nephrology, Cliniques Universitaires Saint-Luc, Brussels, Belgium
*Purpose: Recurrence of anti-glomerular basement membrane (anti-GBM) glomerulonephritis (GN) in the kidney graft is a rare event, described in limited case reports and registry analysis.…2020 American Transplant Congress
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…
