Necrox-7 Inhibits Cell Aggressiveness By Suppressing of NF-Kappa B Activation and Reactive Oxygen Species Generation in Human Rheumatoid Arthritis Fibroblast-like Synoviocytes
Background/Purpose: Rheumatoid arthritis (RA) is characterized by hyperplastic synovial pannus tissue, which mediates destruction of cartilage and bone. Fibroblast-like synoviocytes (FLS) are a key component…Abstract Number: 1616 • 2015 ACR/ARHP Annual Meeting
Identification of Genes Regulating TRAIL-Induced Apoptosis in Rheumatoid Arthritis Fibroblasts-like Synoviocytes (RA FLS)
Background/Purpose: We previously described that sensitivity to TRAIL-induced apoptosis varied in rheumatoid arthritis (RA) fibroblasts-like-synoviocytes (FLS) from one patient to another, and was inversly correlated…Abstract Number: 2714 • 2015 ACR/ARHP Annual Meeting
Rheumatoid Arthritis Synovial Fibroblast Potentiates Mast Cell Degranulation and Migration Independent of Cell-to-Cell Contact
Background/Purpose: A number of studies have shown that synovial mast cells (MCs) are activated, and elicit a pro-inflammatory role in rheumatoid arthritis (RA). Synovial MCs…Abstract Number: 1627 • 2015 ACR/ARHP Annual Meeting
HIF-1alpha Knockdown Down-Regulates Glycolytic Metabolism and Induces Rheumatoid Synovial Fibroblast Cell Death
Background/Purpose: Intense synovial fibroblast (SF) hyperplasia contributes to the chronic inflammation and osteoarticular destruction that characterizes rheumatoid arthritis (RA). Hypoxia-inducible factor 1α (HIF-1α) plays a…Abstract Number: 2719 • 2015 ACR/ARHP Annual Meeting
Track Along: Monocytes Follow Fibroblast-like Synoviocyte Network for Movement and Rest within the Synovial Tissue
Background/Purpose: The synovial lining tissue consists of fibroblast-like synoviocytes (FLS) and monocyte-derived macrophage-like synoviocytes (MLS) within a self-built meshwork of dense extracellular matrix (ECM) components.…Abstract Number: 1915 • 2015 ACR/ARHP Annual Meeting
Pathogenetic Overlap Between Localised and Systemic Scleroderma: A Study of Nodular and Keloidal Morphea Occurring in Systemic Sclerosis
Background/Purpose: Localised scleroderma can occur in overlap with systemic sclerosis (SSc); nodular and keloidal morphea are rare subtypes but can be disfiguring and challenging to…Abstract Number: 3004 • 2015 ACR/ARHP Annual Meeting
Scleroderma Keratinocytes Promote Fibroblast Activation Independent of TGF-ß
Background/Purpose: Systemic sclerosis (SSc) is a devastating fibrosing disease that primarily involves the skin, but may have life-threatening effects on the heart, lungs, gastrointestinal tract,…Abstract Number: 1922 • 2015 ACR/ARHP Annual Meeting
Peripheral B Lymphocytes Secrete Both Interleukin 6 and Transforming Growth Factor-Beta and Potentiate Fibroblast Activation in Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is a rare connective tissue disease characterized by fibroblasts activation, increased extra-cellular matrix synthesis associated with autoimmunity. However, the potential role…Abstract Number: 3007 • 2015 ACR/ARHP Annual Meeting
Cold Receptor Expression and Function in Human Dermal Fibroblast: Possible Role in the Pathogenesis of Scleroderma Fibrosis
Background/Purpose: Enhanced cold sensitivity is an early and consistent phenomenon in scleroderma (SSc). We previously demonstrated increased expression of the transient receptor potential melastatine 8…Abstract Number: 1923 • 2015 ACR/ARHP Annual Meeting
The Role of Inflammatory Myeloid Cell Compartment in Myocardial Fibrogenesis and Remodelling in Systemic Sclerosis
Background/Purpose: During the last years, there was a shift in systemic sclerosis (SSc)-related causes of death, indicating cardiac involvement and inflammatory dilated cardiomyopathy (iDCM) as…Abstract Number: 3008 • 2015 ACR/ARHP Annual Meeting
Role of PTP4A1 Tyrosine Phosphatase in Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is a multi-system autoimmune connective tissue disorder that leads to fibrosis of the skin and internal organs, resulting in significant patient…Abstract Number: 2464 • 2014 ACR/ARHP Annual Meeting
Anti-Arthritic Effect of Tubastatin A, a Novel Histone Deacetylases-6 Inhibitor, Is Mediated By Stabilization of IkB Via Suppression of Ubiquitin-Proteasome Pathway
Background/Purpose: Histone deacetylase-6 (HDAC-6) functions as a non-epigenetic deacetylase for non-histone substrates and regulates microtubule-mediates processes such as cell migration, cell cycle arrest, and angiogenesis.…Abstract Number: 774 • 2014 ACR/ARHP Annual Meeting
Endothelin-1 Synergistically Increases TGF-β-Induced Hif1α Expression Under Normoxic Conditions during Endothelial-to-Mesenchymal Transition in Murine Endothelial Cells. a Novel Mechanism for the Fibrogenic Effects of Endothelin
Background/Purpose: Tissue hypoxia is a consequence of vascular damage and Hif-1α accumulation is a major mechanism of hypoxia response pathways. HIF-1α induces the transcriptional upregulation…Abstract Number: 1969 • 2014 ACR/ARHP Annual Meeting
Neurotrophin Receptor p75 (CD271) Defines a Distinct Synovial Fibroblast Subset in Rheumatoid and Osteoarthritic Synovial Tissues with Enhanced Proinflammatory Potential
Background/Purpose Synovial mesenchynmal or stromal cells constitute a heterogeneous cell population difficult to characterize ex vivo due to a paucity of cell markers and are…
