Activation of Th17 and Chronic Renal Allograft Rejection in Nonhuman Primates
Transplant Center, Massachusetts General Hospital, Boston, MA.
Background: We have previously reported successful induction of renal allograft tolerance in nonhuman primates (NHP) via a mixed chimerism approach. Although donor specific Th1 and…2015 American Transplant Congress
Cognate Events in Antibody- Vs. T Cell-Mediated Rejection: A Molecular Perspective
AIM: The cognate event in antibody-mediated rejection (ABMR) is NK cell FcR engagement; T cell mediated rejection (TCMR) uses TCR engagement. Understanding the molecular changes…2015 American Transplant Congress
2B4 Expression on Human CD4+ Memory T Cells Is Associated With Functional Impairment
Emory Transplant Center, Emory University, Atlata, GA.
The SLAM family receptor 2B4 is expressed primarily on NK cells and memory CD8+ T cells. In prior studies, we found that 2B4 was upregulated…2015 American Transplant Congress
IL-17 Production Influenced by Induction Therapy With ATG
Introduction Immune-mediated rejection remains the most important cause of graft failure. Recently, a newly identified CD4+ T cell subset, Th17, distinct from Th1 or Th2,…2015 American Transplant Congress
Overexpression of 2B4 Inhibits the Expansion and Function of Donor-Reactive CD8+ T Cells in Selective Lymphoid Compartments
Department of Surgery, Emory University, Atlanta, GA.
2B4 is an immunoglobulin superfamily member expressed constitutively on NK cells, and inducibly on some CD8+ T cells. We recently showed in a murine skin…2015 American Transplant Congress
Anti-CD122 + Costimulation Blockade Prolongs Allograft Survival
1Emory Transplant Center, Emory University, Atlanta, GA; 2JN Bioscience, Mountanview, CA.
Introduction: Effective T cell activation and effector function requires (1) cognate antigen recognition (2) appropriate costimulation and (3) successful cytokine signaling. Recently approved strategies to…2015 American Transplant Congress
DNA Methytransferase 1 Inhibition Potently Suppresses T Cell Cycle Progression Through Demethylation of the Key Cell Cycle Inhibitors p15, p16, p21 and p27
Background: Epigenetic mechanisms like acetylation and methylation have been gradually appreciated to play a critical role in the generation and function of various immune cells.…2015 American Transplant Congress
Dual PI3K-mTOR Inhibition on Human T Cell Activation, Proliferation, and Differentiation: The First Step in the Development of New Immunosuppressants
Background: Regulatory T lymphocytes (Tregs) contribute to transplant tolerance. We have demonstrated that the inhibition of PI3K-mTOR pathway has a major role in the differentiation…2015 American Transplant Congress
IL-33 Enhances Host Tolerance to Candida albicans Kidney Infections Through Induction of IL-13 Production by CD4+ T Cells
Susceptibility to systemic Candida albicans infection is determined not only by immune resistance but also by the ability to control Candida-induced immunopathologies. We previously showed…2015 American Transplant Congress
Negative Effects of Being Obese or Overweight on T Regulatory (Treg) Cell Suppressive Function in Patients Listed for Lung Transplantation (Tx)
Aim: Obese and overweight patients may be prone to adverse outcomes following lung Tx. We sought to determine the relationship between body mass index (BMI)…
