Genetically Modified Porcine Erythrocytes: A Cell Model for Studying Human Preformed Antibody-Dependent Xenoimmune Responses In Vitro
Surgery, University of Alabama at Birmingham, Birmingham, AL.
Background: Powerful gene editing technology is a promising approach to provide genetically-modified pigs as donors for clinical cell, tissue and organ xenotransplantation. Prior to starting…2018 American Transplant Congress
Mitochondrial Quality Control through PGC-1α in Syngenic Mouse Heart Transplant
1Anesthesiology, Duke University, Durham, NC; 2Surgery, Duke University, Durham, NC.
Intro: Impaired mitochondrial function plays a role in graft dysfunction after transplant, and recovery is facilitated by mitochondrial quality control (MQC). Two key elements of…2018 American Transplant Congress
Mitochondrial Autophagy Proteins Bnip3 and Nix Maintain Memory B Cell Survival
Despite the use of immunosuppressive drugs, allograft rejection remains a major hurdle for the long-term success of organ transplants. Burgeoning evidence implicates memory B cells…2018 American Transplant Congress
T-bet and STAT6 Double Deficiency Favors IL-17 Immunity after Lung Transplantation
Background: The long-term success of lung transplantation is mainly limited by the development of obliterative bronchiolitis (OB) in which IL-17 plays a critical role. Direct…2018 American Transplant Congress
Upregulated IL-33 in Heart Transplants Modulates Local Myeloid Populations to Protect against Chronic Allograft Rejection
Purpose: Interleukin-33 (IL-33) is an “alarmin”, or a self-derived molecule that triggers pleotropic immune responses after release from damaged tissue. Yet, how IL-33 shapes alloresponses…2018 American Transplant Congress
Ablation of Both mTOR and STAT3 in T Cells Induces Heart Transplant Acceptance in Donor Skin-Sensitized Mice
Allogeneic memory T cell response precludes the induction of transplant acceptance; how this process is regulated at the molecular level remains unclear. Both mTOR and…2017 American Transplant Congress
Dendritic Cell Expression of Rictor (mTORC2), but Not Raptor (mTORC1), Protects Against Renal Ischemia-Reperfusion Injury.
Background: Dendritic cells (DC) are critical initiators of innate immunity in the kidney and orchestrate inflammation subsequent to ischemia-reperfusion injury (IRI). The mechanistic target of…2017 American Transplant Congress
Macrophage Specific Deletion of RhoA Inhibits Fractalkine Signaling and Abrogates Chronic Rejection of Cardiac Allograft.
Surgery, Houston Methodist Hospital and Research Institute, Houston
Objective. Chronic rejection of transplanted organs remains unresolved issue in organ transplantation. The chronic rejection is the most common cause of graft loss within 10…2017 American Transplant Congress
Abrogating MyD88 Signaling in Donor Lung Resident Hematopoietic Cells Promotes Cell Based Tolerance Induction in Lung Allografts in Mice.
Objectives: MyD88 signaling plays an important role in allograft rejection and tolerance induction. This study is designed to determine the cellular base of MyD88 expression…2017 American Transplant Congress
Deleting LAG-3 Accelerates Cardiac Allograft Rejection and Augments T Cell Memory in Mice.
Purpose: Lymphocyte Activation Gene-3 (LAG-3) expresses a transmembrane receptor on activated immune cells such as T cells, NK cells, and plasmacytoid dendritic cells. It is…
