Role of NRP1 in CD4+ T Cell Allo-Activation.
Department of Surgery, Boston Children's Hospital, Boston, MA.
Introduction: Neuropilin-1 (NRP1) is a transmembrane glycoprotein that functions as a co-receptor for class III/IV semaphorins, VEGF, and several other growth factors. NRP1 has been…2016 American Transplant Congress
Contributions of Naive vs. Endogenous and Induced Alloreactive Memory T Cells in Mixed Lymphocyte Reactions.
Surgery, MGH/Harvard Medical School, Boston, MA.
T lymphocytes isolated from naïve, unmanipulated mice, proliferate and secrete cytokines when cultured in vitro with allogeneic irradiated leukocytes. This in vitro response known as…2016 American Transplant Congress
ESAT-6 Inhibits Donor-Specific Memory CD8+ T Cell Generation and Alloimmune Responses.
Inducing long-term transplant survival or tolerance without continuous global immunosuppression is a highly desired goal in organ transplantation because conventional immunosuppressive drugs usually cause severe…2016 American Transplant Congress
Low Pretransplant BMI/Weight and Changes in Posttransplant T Cell Exhaustion Levels Are Associated with Viremia/Viral Infection in Pediatric Kidney Transplantation in the First Post-Transplant Year – A Report from the IMPACT Study Consortium.
Viral consequences of immunosuppression (IS) in pediatric(ped)kidney(kid)transplantation(Tx)patients(pts) are not fully known. We prospectively examined the immunologic and infectious (inf) history of 106 ped Tx pts…2016 American Transplant Congress
Combined CD122 and Costimulation Blockade Prolongs Allograft Survival by Controlling Expansion and Effector Function of Memory CD8 T Cells.
1Emory Transplant Center, Emory University, Atlanta, GA; 2JN Biosciences, Mountain View, CA.
CD8 memory T cells rely on signaling through CD122, the shared IL-2 and IL-15 receptor β-chain. The addition of anti-CD122 to costimulation blockade prolongs graft…2016 American Transplant Congress
Successful Treatment of Established Acute Allograft Rejection with Delayed CTLA-4Ig.
Purpose: Our goal was to determine the efficacy and immune mechanisms of costimulation blockade by CTLA-4Ig when treatment begins after an immune response is already…2016 American Transplant Congress
Resveratrol Effectively Suppress Th17 Associated Allo-Immune Responses by the Modulation of AMPK/mTOR Pathway.
The aim of this study is to investigate the effect of resveratrol on Th17 allo-immune responses under tacrolimus (Tac)-based immune suppression. First, we investigated the…2016 American Transplant Congress
Aging Is Critically Impacting the Efficacy of Immunosuppressants.
Immunosenescence is broadly affecting alloimmunity with major implications on immunosuppression. Older recipients have thus far been mostly excluded from clinical trials. Here, we dissected the…2016 American Transplant Congress
Mass Cytometry Reveals NK Cell and T Cell Subsets in Pediatric Liver Transplant Patients with Acute Rejection.
1Pediatrics, Stanford/LPCH, Palo Alto, CA; 2Surgery, Stanford, Palo Alto, CA.
Proper evaluation of the immune status of liver transplant recipients is crucial for appropriate post-transplant management. Current monitoring of graft function relies mainly on non-specific…2016 American Transplant Congress
An Interventional Study Evaluating Cell Mediated Immunity to Guide Therapy for CMV Viremia.
Multi-Organ Transplant, University Health Network, Toronto, ON, Canada.
BackgroundPatients treated for CMV viremia commonly relapse after discontinuation of therapy. CMV-specific CD8+ T-cell mediated immunity (CMI) is useful to predict the risk of CMV…
