Unique Genomic & Proteomic Profile of Liver Mesenchymal Stromal Cells is Associated with Their Superior Immunomodulatory Properties
Transplant Center, Mayo Clinic, Rochester, MN
*Purpose: Investigating mechanisms of liver allografts’ relative tolerance, we recently reported that liver mesenchymal stromal cells (L-MSC) are superior in their capacity to inhibit alloimmune…2020 American Transplant Congress
MHC II-Decoy Car-T Cells to Induce Long-Term Allotransplant Organ Tolerance
*Purpose: Allotransplantation represents the definitive therapy for end-stage renal, heart, liver, and lung disease. Current immunosuppressive regimens fail to promote long-term engraftment, leading to chronic…2020 American Transplant Congress
Human, Monkey Transplant Tolerance and IL35 “Exokine
1University of Wisconsin, Madison, WI, 2Surgery, University of Wisconsin, Madison, WI
*Purpose: Studies in B6 (H2b) mice tolerized to CBA (H2k) have shown that induced allospecific Tregs make 2 very different forms of immunoregulatory cytokines: 1)…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
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…2019 American Transplant Congress
IL-21 Induces the Transformation of Th Cell Subsets in Acute Rejection after Kidney Transplantation
Kidney Disease Center, First Affiliated Hospital of Zhejiang University, Hangzhou, China
*Purpose: IL-21 exhibits a wide range of immunomodulatory functions in the organism, regulating immune cells such as B cells and T cells. In this study,…2019 American Transplant Congress
Allograft Survival is Influenced by Gut Microbiota-Dependent Modulation of Innate Immunity
*Purpose: The gut microbiota driven inflammatory response and the host immune system engage bidirectional regulation of each other. These interactions are poorly characterized in organ…2019 American Transplant Congress
Murine Cmv Infection Impairs Transplantation Tolerance: A Critical Role Of Intragraft Anergic Cd4 T Cells
1Medicine, Duke University, Durham, NC, 2Pathology, Northwestern University, Chicago, IL
*Purpose: It is well known that certain infections can impair the stability of transplantation tolerance in recipients who had prolonged functional grafts, resulting in graft-loss.…2019 American Transplant Congress
Laminin α5 Deficiency in Lymph Node Stromal Cells Promotes Treg Migration and Allograft Survival
Surgery, U. Maryland, Baltimore, Baltimore, MD
*Purpose: Laminins are a family of heterotrimeric glycoproteins, and lymph node (LN) stromal laminins α4 and α5 modulate suppression and immunity, respectively. We created laminin…2019 American Transplant Congress
Withaferin A Shifts Circulating Lymphocytes toward Protective T Cell Subsets and Prolongs Islet Allograft Survival in a Mouse Transplant Model
*Purpose: : Immunosuppression protocols improve the efficacy of allogeneic islet transplantation. However, decline in islet graft function and toxicities imposed by current immunosuppressant drugs remain…
