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…2020 American Transplant Congress
The Gut Microbiota Stimulates Dendritic Cells for Immune Modulation
University of Maryland, Baltimore, Baltimore, MD
*Purpose: The gut microbiota is a driving force in host immune regulation, and thus a potential target for intervention and drug development. We previously showed…2020 American Transplant Congress
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…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…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…
