Pro- and Anti-Tolerogenic Microbiota Induce Distinct Gut Microbiome Metabolic Pathways and Loco-Regional Immune Responses
1University of Maryland School of Medicine, Baltimore, MD, 2University of Maryland, Baltimore, MD
*Purpose: Colitis-associated Desulfovibrio desulfuricans (Desulfo) induces pro-inflammatory cytokine responses in dendritic cell and macrophage cell lines as well as primary cells. In contrast, Bifidobacterium pseudolongum…2022 American Transplant Congress
Bioink Based on the DECM for 3D-Bioprinting of Bionic Pancreas – First Results of Animal
*Purpose: Tissue engineering is an interdisciplinary field involving activities based on two interrelated areas: developing new methods to repair, regenerate and replace damaged tissues and…2022 American Transplant Congress
P2X7R Inhibition Impairs In Vitro Training of Macrophages
*Purpose: Macrophage training and ATP-mediated P2X7R signaling are unrelated key elements of the innate immune response associated with allotransplant rejection. In the present study, we…2022 American Transplant Congress
Type 1 Natural Killer T-cells: Key Mediators of Ischemia- Reperfusion Injury in Hepatic Steatosis
*Purpose: Hepatic ischemia-reperfusion injury (IRI) poses a significant risk in liver transplantation and hepatic resection and is further exacerbated by hepatic steatosis. Type 1 Natural…2022 American Transplant Congress
Portal Hypertension Inhibits the Antitumor Effect of Liver-Resident NK Cells Through IL-33 Signal
Hiroshima University, Hiroshima, Japan
*Purpose: Portal vein hypertension (PHT) after living donor liver transplantation (LDLT) is known to have associated with poor prognosis. Among patients with hepatocellular carcinoma (N=…2022 American Transplant Congress
Non-Invasive Assessment of Hepatic Ischemia-Reperfusion Injury Using Dynamic Contrast Enhanced-MRI and T2 Mapping
*Purpose: Hepatic ischemia-reperfusion injury (IRI) is a consequence of liver transplantation and hepatectomy that varies in severity and clinical significance. The diagnosis is made based…2022 American Transplant Congress
Exosomal TGFbeta:LAP as Immunosuppressive Mediator of Allo-Tolerance
*Purpose: TGFβ has long been known as a key component in tolerance mediated by Treg cells. Here we show that, unlike IL10, but like CD39/CD73,…2022 American Transplant Congress
Autophagy is an Important Factor in the Development of Fibrosis Following Renal Injury; Implications for Post-Transplant IFTA
*Purpose: Interstitial Fibrosis and Tubular Atrophy (IFTA) is the most common cause of long-term graft failure following renal transplant. There is currently no effective therapy.…2022 American Transplant Congress
Protective Immunity Against a Murine Epstein-Barr Virus Homolog is Preserved During CD11b-CD154 Blockade
Emory University Transplant Center, Emory University, Atlanta, GA
*Purpose: CD154 pathway antagonism has shown to be a promising target for inducing long-time graft survival, in some cases showing efficacy that is superior to…2021 American Transplant Congress
Single-Cell RNA-seq Identifies Intra-Graft Population Heterogeneity in Acute Heart Allograft Rejection in the Mouse
*Purpose: Transplant rejection remains a major barrier to graft survival and involves a diversity of cell types. But the heterogeneity in a given cell type…
