Torc1 Inhibition Protects Activated Human Regulatory T Cells from Self-Inflicted Damage via Granzyme B
Transplantation Research Center, Brigham and Women's Hospital, Harvard Medical School, Boston, MA
*Purpose: The use of Regulatory T cells (Tregs) in adoptive cell therapy has been hindered by their short survival following their adoptive transfer. We have…2020 American Transplant Congress
Immuno-Modulation of Primed Xenogeneic T Cell Response by mTOR Blockade of T Cells and Porcine Endothelial Cells
Surgery, Duke University, Durham, NC
*Purpose: Porcine vascular endothelial cells (PECs) play a central role in xeno-recognition and costimulation. The objectives of this study were to characterize the immuno-phenotype of…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…2020 American Transplant Congress
Is it Time for Immune Screening for Belatacept-Treated Stable Kidney Transplant Patients for Adjust the Immunosuppression?
1ITAC, Buenos Aires, Argentina, 2CEFYBO, UBA, Buenos Aires, Argentina
*Purpose: Belatacept is a co-stimulation blocker for primary maintenance immunosuppression in kidney transplant recipients. The goal of this work was to study the immunological status…2020 American Transplant Congress
Effector Differentiation of Endogenous Antigen-Specific CD8+ T Cells is Selectively Limited by CTLA-4 Ig
Emory Transplant Center, Emory University School of Medicine, Atlanta, GA
*Purpose: Costimulation blockade with belatacept (CTLA-4 Ig) offers improved renal function and reduced toxicity following transplantation compared to calcineurin inhibitors. Nonetheless, episodes of acute T…2020 American Transplant Congress
Peripheral Blood RNA Sequencing Unravels a Differential Role of Coding and Non-Coding Genes by Types of Kidney Allograft Rejection
*Purpose: Peripheral blood molecular patterns characterizing the different effector immune pathways driving kidney allograft rejection remain to be fully completely elucidated, to more fully type…2020 American Transplant Congress
Lateral Flow Assay to Detect Soluble CD25 after Kidney Transplantation
Faculty of Natural Sciences, Institute of Technical Chemistry, Hannover, Germany
*Purpose: Kidney transplantations are one of the most common transplantations in the world; 80.696 kidneys were transplanted in 2017. Despite tremendous improvements in quality and…2020 American Transplant Congress
Autophagy-Lysosome Inhibitor Chloroquine Prevents CTLA-4 Degradation of T Cells and Attenuates Acute Rejection in Murine Skin and Heart Transplantation
*Purpose: The immune checkpoint cytotoxic T lymphocyte antigen-4 (CTLA-4), which was induced upon T cell activation but degraded quickly, has been targeted in the clinical…2020 American Transplant Congress
Hemodialysis (HD) Treatment Associates with Increased Risk of Delayed Graft Function (DGF) after Renal Transplantation (RT) and Augmented Cd4 and Cd8 T Cell Proliferation Compared to Peritoneal Dialysis (PD)
*Purpose: Delayed graft function (DGF) is a common event after RT that increases the risk of acute rejection and early graft loss. The impact of…2020 American Transplant Congress
Notch Signaling Inhibition via Blockade of Delta-Like Ligand 4 Prevents Co-Stimulation Blockade Resistant Allograft Rejection
Surgery and Transplantation, Emory University, Atlanta, GA
*Purpose: Co-stimulation blockade (CoB) has emerged as a promising immunosuppression strategy with the advent of Belatacept, a novel CTLA4-Ig fusion protein that blocks CD28-mediated T…
