The Indole Derivative NecroX Blocks Th17 Cell Differentiation and Fibroblast-like Synoviocytes-mediated Th1/Th17 Responses in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of synovium, which causes progressive joint destruction and reduction in quality of life.…Abstract Number: 781 • 2019 ACR/ARP Annual Meeting
Is down Syndrome Associated Arthritis (DA) a Distinct Disease from Juvenile Idiopathic Arthritis (JIA)?
Background/Purpose: Down syndrome associated Arthritis (DA) is 20 times more common than JIA. It is an erosive, polyarticular RF negative arthritis with predominance in the…Abstract Number: 1985 • 2019 ACR/ARP Annual Meeting
Divergent Mononuclear Cell Participation and Cytokine Release Profiles Define Hip and Knee Osteoarthritis
Background/Purpose: Osteoarthritis (OA) is a progressive joint disease driven by a blend of inflammatory and biomechanical processes. Studies using human samples to understand inflammatory mechanisms…Abstract Number: 2060 • 2018 ACR/ARHP Annual Meeting
Comparative Histologic and Molecular Analysis of Synovial Tissue in Early Treatment-Naïve Psoriatic and Rheumatoid Arthritis
Background/Purpose: Rheumatoid Arthritis (RA) and Psoriatic Arthritis (PsA) are chronic joint conditions characterised by persistent inflammation of the synovial tissue (ST). Previous reports suggested less…Abstract Number: 10 • 2018 ACR/ARHP Annual Meeting
Fibroblast like Synoviocytes (FLS) Are Capable of Inducing Phenotypical Changes Including Class Switch Recombination (CSR) in Naive B Cells, but Additional Factors Are Required to Trigger Immunoglobulin Secretion
Background/Purpose: Rheumatoid Arthritis (RA) is a disease characterized by chronic inflammation of the synovial tissue in joints. It is driven by highly activated B cells.…Abstract Number: 46 • 2018 ACR/ARHP Annual Meeting
Organic Dust Inhalants Shift Immune Responses and Extracellular Matrix Balance between Synovium and Lung in the Collagen-Induced Arthritis Mouse Model
Background/Purpose: Emerging evidence suggests that the lungs may be an initiating site of autoimmunity leading to RA with organic inhalant exposures such as those…Abstract Number: 928 • 2018 ACR/ARHP Annual Meeting
Single Cell RNA-Sequencing of Rheumatoid Synovial Fibroblasts Reveals a Disease-Associated Spatial Gradient Modulated By Inductive Notch Signaling
Background/Purpose: In rheumatoid arthritis (RA), tissue resident fibroblasts orchestrate chronic inflammation and regulate pathologic bone and cartilage remodeling that causes irreversible joint damage. Recently, we…Abstract Number: 1045 • 2018 ACR/ARHP Annual Meeting
The Coll2-1 Peptide of Collagen Type II: A New Actor of Synovitis in Osteoarthritis
Background/Purpose: We evaluated the inflammatory effect of Coll2-1 peptide in osteoarthritic synoviocytes and rats by comparing peptide-induced inflammatory reaction with the one induced by bovine…Abstract Number: 1053 • 2018 ACR/ARHP Annual Meeting
Synovial Inflammation Identifies Patients Clusters in Osteoarthritis
Background/Purpose: Synovial membrane inflammation is common in osteoarthritis (OA). Inflammation may be present at all disease stages, increases the risk of cartilage injury, and is…Abstract Number: 1078 • 2018 ACR/ARHP Annual Meeting
Standardization of Synovial Biopsies Procedures across Centers: A Consensus Initiative Using a Delphi Survey
