Imbalance Between Histone Acetyl Transferase and Histone Deacteylase Activities and Modulation of HDAC Activity and Tnfa Production by HDAC Inhibitors in Patients with Ankylosing Spondylitis or Rheumatoid Arthritis
Background/Purpose: TNFa is a major cytokine involved in conditions such as ankylosing spondylitis (AS) and rheumatoid arthritis (RA). Epigenetic regulation corresponds to different processes including…Abstract Number: 874 • 2012 ACR/ARHP Annual Meeting
TNFα Induces Sustained Signaling and a Prolonged and Unremitting Inflammatory Response in Synovial Fibroblasts
Background/Purpose: The non resolving character of synovial inflammation in rheumatoid arthritis (RA) is a conundrum. To identify the contribution of fibroblast-like synoviocytes (FLS) to the…Abstract Number: 875 • 2012 ACR/ARHP Annual Meeting
Discovery of Pharmacologic MIF Antagonists by Structure-Based Molecular Design
Background/Purpose: Cytokine inhibition is becoming a mainstay for the therapy of autoimmunity but current antibody-based approaches remain limited by high cost, parenteral administration, and anti-idiotype…Abstract Number: 876 • 2012 ACR/ARHP Annual Meeting
Xanthine Oxidase-Derived ROS Direct Context-Dependent Action of NFAT5 Toward Inflammatory Response in Macrophages
Background/Purpose: NFAT5, a well known osmo-protective factor, can be activated by isotonic stimuli, such as Toll-like receptor (TLR) triggering. Here, we identified a novel signal…Abstract Number: 877 • 2012 ACR/ARHP Annual Meeting
Aberrant Expression of BAFF Receptor (BR3) in Peripheral Monocytes of Patients with Primary Sjögren’s Syndrome Impacts Abnormal Activation of BAFF Signaling Through IKK-Alphaand IKK-Beta
Background/Purpose: B cell activating factor belonging to the TNF superfamily (BAFF) regulates proliferation, differentiation and survival of B cells and plays a pivotal role in…Abstract Number: 878 • 2012 ACR/ARHP Annual Meeting
Differential Regulation of Cytokines by Extracellular-Signal Regulated Kinase and c-Jun N-Terminal Kinase in Map Kinase Kinase-3 and -6 Deficiency
Background/Purpose: p38 inhibitors have limited efficacy in rheumatoid arthritis (RA), possibly because p38 blockade suppresses IL-10 production and increases JNK and ERK phosphorylation in…Abstract Number: 879 • 2012 ACR/ARHP Annual Meeting
Fucosyltransferase 1 (fut1) Is Overexpressed in Rheumatoid Arthritis Synovial Tissue and Modifies Cytokine Production
Background/Purpose: Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by inflammation and joint destruction. Angiogenesis and cytokine production are involved in the pathogenesis of…Abstract Number: 880 • 2012 ACR/ARHP Annual Meeting
Interferon Regulatory Factor 8 Regulates BAFF Production in Murine Macrophages and Is a Nexus for Cross Talk Between IFN-γ and TGF-β
Background/Purpose: Lupus is a systemic autoimmune disease that can lead to severe end-organ damage characterized by unabated inflammation and aberrant tissue repair. Macrophage dysregulation plays…Abstract Number: 881 • 2012 ACR/ARHP Annual Meeting
Microrna-155 Regulates Chemokines and Chemokine Receptors in Rheumatoid Arthritis Monocyte
Background/Purpose: Rheumatoid arthritis (RA) is characterized by synovial tissue inflammation leading to joint destruction. Monocytes/macrophages are major effector cells in RA synovitis, principally by releasing…Abstract Number: 882 • 2012 ACR/ARHP Annual Meeting
Anti-Inflammatory Effects of Phosphodiesterase 4 Inhibition Are Mediated by Mitogen-Activated Protein Kinase Phosphatase-1
Background/Purpose: MAP kinase phosphatase-1 (MKP-1) is a nuclear tyrosine/threonine phosphatase that limits p38 MAP kinase activity. MKP-1 KO mice display excessive inflammatory response, and exhibit…Abstract Number: 883 • 2012 ACR/ARHP Annual Meeting
Role of Phospholipase D1 (PLD1) in the Expression of Proinflammatory Genes in Rheumatoid Arthritis Synovial Fibroblasts (RASF)
Background/Purpose: Interleukin-17 (IL-17) and Tumor Necrosis Factor alpha (TNFa), when co-applied to RASF, induce synergistic expression of proinflammatory genes such as IL-6 and IL-8. Work…Abstract Number: 884 • 2012 ACR/ARHP Annual Meeting
Receptor Activator of Nuclear Factor ÊB Ligand-Mediated Osteoclastogenesis Is Augmented by Interleukin-1â Via up-Regulation of Endoplasmic Reticulum Stress Signals
Background/Purpose: Interleukin-1β (IL-1β) and thapsigargin (TG)-augmented endoplasmic reticulum (ER) stress modulate the receptor activator of nuclear factor kappa-B ligand (RANKL)-mediated osteoclastogenesis. However, the mechanism by…Abstract Number: 885 • 2012 ACR/ARHP Annual Meeting
Interferon α and Self-Organized Criticality Theory
Background/Purpose: One of the biggest obstacle we face in elucidating the pathogenesis of autoimmunity today is the mechanism how autoreactive lymphocyte clones could survive or…Abstract Number: 886 • 2012 ACR/ARHP Annual Meeting
