    Optimal Development and Effector Function of Antibody-Suppressor CXCR5+CD8+ T Cells Requires Host IFN-γ and CD4+ T Cells

    J. Zimmerer, S. Chaudhari, M. Hart, J. Han, K. Koneru, G. Bumgardner

    OSUWMC, Columbus, OH

    *Purpose: We reported the discovery of a novel subset of CXCR5+IFNγ+CD8+ T cells that suppresses antibody production (CD8+ TAb-supp cells). Alloprimed CD8+ TAb-supp cells significantly…

    The Role of T Lymphocyte Subsets in Kidney Transplantation

    L. Vagiotas1, A. Xochelli2, E. Sampani3, V. Nikolaidou2, D. Asouchidou2, E. Kasimatis3, N. Antoniadis1, M. Daoudaki4, M. Stangou3, A. Papagianni3, G. Tsoulfas1, A. Fylaktou2

    1Division of Organ Transplantation, Department of Surgery, Aristotle University Medical School, Hippokration Hospital, Thessaloniki, Greece, 2National Peripheral Histocompatibility Center, Immunology Department, Hippokration Hospital, Thessaloniki, Greece, 3Department of Nephrology, Aristotle University Medical School, Hippokration Hospital, Thessaloniki, Greece, 4Laboratory of Biological Chemistry, Faculty of Medicine Aristotle University of Thessaloniki, Thessaloniki, Greece

    *Purpose: Impairment of cellular immune function in kidney transplant candidates is not concomitantly restored with the recovery of renal function, as alloimmune response and implementation…

    TNX-1500, an Fc-Modified Anti-cd154 Antibody, Prolongs Nonhuman Primate Cardiac Allograft Survival

    S. Miura1, Z. Abady1, F. Pollok1, M. Ma1, K. Kinoshita1, S. Fogarty2, P. Maguire2, B. Daugherty2, S. Lederman2, R. Pierson III1

    1Center for Transplantation Sciences, Department of Surgery, Massachusetts General Hospital, Boston, MA, 2Tonix Pharmaceuticals, Chatham, NJ

    *Purpose: Blockade of the CD40/CD154 T cell costimulation pathway is a promising approach to replace current clinical immunosuppression. TNX-1500 (TNX) is a novel humanized anti-CD154…

    CD8+ T Cells Differentiate into a CD43-expressing Effector Population After Transplantation

    G. Cohen, M. A. Kallarakal, S. M. Krummey

    Department of Pathology, Johns Hopkins University, Baltimore, MD

    *Purpose: Despite a significantly reduced toxicity profile and improved long-term graft function versus calcineurin inhibitors, widespread adaptation of belatacept (CTLA-4 Ig) has been limited due…

    Targeted Delivery of Costimulation Inhibitor to Lymph Nodes Promotes Transplant Tolerance via Fibroblastic Reticular Cells

    J. Zhao1, S. Jung1, X. Li1, H. Zhang1, S. Movahedi1, V. Kasinath1, M. Uehara1, J. Azzi1, P. Sage1, S. Tullius1, J. S. Bromberg2, R. Abdi1

    1Brigham and Women's Hospital, Boston, MA, 2University of Maryland School of Medicine, Baltimore, MD

    *Purpose: The lymph node (LN) is the primary site of alloimmunity activation and regulation during transplantation. Fibroblastic reticular cells (FRCs), the prominent cells of the…

    MTOR Inhibition Acts Directly on Endothelial Cells to Induce Contact-Independent Immune-Modulation of Allo-Specific T Cell Activation

    H. Xu, L. Wang, V. A. Bendersky, Q. Gao, Q. Li, A. D. Kirk, H. Xu

    Duke University School of Medicine, Durham, NC

    *Purpose: Endothelial cells (ECs) form a barrier between vascularized organ allografts and host immunity and are known to provoke alloimmune responses. The mTOR inhibitor rapamycin…
