cDC1-Mediated Prolongation of Cardiac Allograft Survival and Alloantigen Induced Transcriptional Programming
Pathology, Northwestern Feinberg School of Medicine, Chicago, IL
*Purpose: Heart transplantation is currently the only treatment for advanced stage heart failure. While patient survival after transplantation has improved acutely, the same cannot be…2022 American Transplant Congress
Identification of a Human B Cell State with Allogeneic Antigen Cross-Presenting Potential
Radiation Oncology, Dana-Farber Cancer Institute, Boston, MA
*Purpose: B cells are known to play a significant role in allograft tolerance or rejection, largely determined by production of cytokines and antibodies that suppress…2022 American Transplant Congress
Validation of Shared T Cell Epitope Analysis as a Tool to Detect Preformed Donor-Reactive CD4+ Memory T-helper Cells
*Purpose: Adaptive immunity creates immunological memory after the first response to a specific foreign antigen including HLA. During this response, adaptive immunity memorizes the molecular…2022 American Transplant Congress
Dendritic Cell Senescence as a Key Contributor to Transplant Rejection
1Brigham and Women’s Hospital, Boston, MA, 2University of Maryland School of Medicine, Baltimore, MD
*Purpose: Intra-graft inflammation initiated by ischemia-reperfusion injury (IRI) is an unavoidable consequence of transplantation surgery and constitutes a key source of alloimmune responses. IRI leads…2021 American Transplant Congress
Accelerated Bronchiolitis Obliterans After Lung Transplant Promoted by an ATG16L1 Mutation is Coupled to Mitochondrial Damage and Metabolic Alterations in Monocyte-derived Antigen Presenting Cells
1Washington University, Saint Louis, MO, 2UT Southwestern Medical Center, Dallas, TX
*Purpose: Bronchiolitis obliterans (BOS) remains a major cause of death for lung transplant recipients, and the mechanisms that drive BOS remain poorly understood. It is…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
Precision Medicine in Renal Transplantation: Structural Biology of HLA Defines Allelic Binding of Cardinal Pathogenic Viruses in Transplantation
*Purpose: The incidence, clearance and clinical expression of viremia post-Tx are heterogeneous, complicating prediction, prognosis and therapy. We postulated that variation viral presentation related to…2021 American Transplant Congress
Inhibition of Fatty Acid Beta-Oxidation Prolongs Heart Allograft Survival
Surgery, Washington University School of Medicine, Saint Louis, MO
*Purpose: To test the therapeutic efficacy of pharmacological inhibition of fatty acid beta-oxidation (FAO) on acute heart allograft survival.*Methods: We used a heterotopic Balb/c donor…2021 American Transplant Congress
The Development and Characterization of AT1501, an Anti CD40L Antibody Lacking Fc Effector Function
1Novus Therapeutics, Irvine, CA, 2ALS Therapy Development Institute, Cambridge, MA
*Purpose: CD40L is a costimulatory type II membrane receptor for CD40. The binding of CD40L on T helper cells to CD40 on antigen presenting cells…2021 American Transplant Congress
DAP12 Promotes Liver DC Tolerogenicity by Negative Regulation of the CGAS-STING-IFN I Pathway
*Purpose: Constitutive expression of comparatively high levels of DNAX-activating protein of 12KDa (DAP12) by liver myeloid dendritic cells (mDCs) has been implicated in their immune…
