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…2016 American Transplant Congress
Type-I Interferon Induced Cross-Competition of IL-10 Signaling and Its Role in the Abrogation of Transplant Tolerance.
Plastic Surgery, Johns Hopkins University, School of Medicine, Baltimore, MD.
PurposeA growing body of evidence shows that induction of long term transplant survival by “costimulation blockade” (CoB) regimens is impaired by inflammatory responses. In particular,…2015 American Transplant Congress
Effective Control of Anti-Xenogeneic IL-17 Response for Tolerance Induction in Xenogeneic Islet Cell Transplantation
We have previously shown that peri-transplant infusion of donor cells treated with 1-ethyl-3-(3'-dimethylaminopropyl)-carbodiimide (ECDI) in combination with peri-transplant anti-CD20 and rapamycin induce permanent porcine islet…2015 American Transplant Congress
PI3Kα and STAT1 Interplay Regulates Human Mesenchymal Stem Cell Immune Polarization
The immunomodulatory capacity of mesenchymal stem cells (MSC) is critical for their use in therapeutic applications. MSC response to specific inflammatory cues allows them to…2015 American Transplant Congress
Targeted Rapamycin Nanotherapy Dampens Memory T Cell Function
Memory T cells (Tm) are difficult to control post-transplantation and account for early rejection episodes. Additionally, therapies exerting local immunosuppression by targeting an allograft, while…2015 American Transplant Congress
Assessing Pre-Vaccination Cytokine Levels to Predict Immunogenicity to Seasonal Trivalent Influenza Vaccine in Solid Organ Transplant Recipients
Multi-Organ Transplant Program, University Health Network, Toronto, Canada.
Background: The immunogenicity of seasonal trivalent influenza vaccine (TIV) in solid organ transplant (SOT) recipients remains suboptimal. We hypothesized that analysis of pre-vaccination T- and…2015 American Transplant Congress
Evaluation of Natural Killer Cell Activation by NK Cell-Specific Interferon-Gamma-Releasing Assay
Introduction: Although NK cell activity (NKA) has a variety of measuring markers including chromiun release assay and flowcytometry-based cytolysis, limitations such as radioactivity and lack…2015 American Transplant Congress
IFNγ Is Required for nTreg Afferent Lymphatic Migration
Surgery, University of Maryland, Baltimore, MD.
Background: Natural Treg (nTreg) must migrate from graft to draining lymph node (LN) to prolong islet allograft survival, and we previously showed that the transcription…
