Involvement of Mast Cells in the Pathogenesis of Sjögren’s Syndrome By Induction of Tissue Fibrosis Via Fibroblast Collagen Synthesis
Background/Purpose: There is an emerging view that mast cells may play a pivotal role in several inflammatory and autoimmune diseases. However, the role of mast…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: 2035 • 2018 ACR/ARHP Annual Meeting
Effect of Baricitinib on Joint-Related Biomarkers in Patients with Moderate-to-Severe Rheumatoid Arthritis
Background/Purpose: Baricitinib (bari) is an oral selective inhibitor of Janus kinase (JAK) 1 and JAK2. In the phase 3 study RA-BUILD (NCT01721057), once-daily bari yielded…Abstract Number: 2688 • 2017 ACR/ARHP Annual Meeting
Collagen Metabolite Biomarker Levels Are Associated with the Amount of Fibrosis in Internal Organs in Systemic Sclerosis Patients
Background/Purpose: Biomarkers that can monitor the fibrotic burden will aid in trial enrichment and personalized health care in SSc. SSc is associated with internal organ…Abstract Number: 465 • 2017 ACR/ARHP Annual Meeting
Basement Membrane Remodeling in Rheumatoid Arthritis Associates with Disease Activity, Response to IL-6 Inhibitor Treatment and Radiographic Progression: Analysis of Two Phase III Clinical Trials
Background/Purpose: Rheumatoid arthritis (RA) is associated with neovascularization of the synovial membrane and increased risk of cardiovascular co-morbidity. The extra cellular matrix below the endothelial…Abstract Number: 489 • 2017 ACR/ARHP Annual Meeting
Endotypic Clustering of Rheumatoid Arthritis Patients through the Use of Tissue Specific Serum Biomarkers Identifies Structural Progressors
Background/Purpose: Treatment of RA patients is guided by measures of disease activity such as DAS28, best practice recommendation, and less often by a treat-to-target approach.…Abstract Number: 762 • 2017 ACR/ARHP Annual Meeting
M10, a Caspase Cleavage Product of the Hepatocyte Growth Factor Receptor, Downregulates Bone Morphogenetic Protein-9-Induced Smad1/5/8 Phosphorylation and Collagen Production in Human Lung Fibroblasts
Background/Purpose: We recently identified M10, a caspase cleavage product of the hepatocyte growth factor receptor, as an anti-fibrotic peptide that interacts with Smad2 and inhibits…Abstract Number: 1226 • 2017 ACR/ARHP Annual Meeting
Association of Dorsal Flat Vertebra/Platyspondylia As a Form of Vertebral Dysplasia within Type II Collage Disorders
Background/Purpose: Defects in the type II collagen gene are described. These predispose humans to various phenotypic combinations in families with skeletal dysplasia, and/or disease by…Abstract Number: 1725 • 2017 ACR/ARHP Annual Meeting
Insulin-like Growth Factor Binding Protein-4 Exerts Anti-Fibrotic Effects and Its Levels Are Reduced in SSc-Associated Lung Fibrosis
Background/Purpose: The Insulin-like growth factor (IGF) system plays an important role in cellular growth, proliferation, differentiation, apoptosis and transformation; IGF binding proteins (IGFBP) exert cell…Abstract Number: 1930 • 2017 ACR/ARHP Annual Meeting
Interleukin 1β Decreases Capacity for Repair Human Cartilage Lesions By Mesenchymal Stromal Cells on Collagen/Proteoglycan Scaffolds
Background/Purpose: There is controversy about the effect of catabolic cytokines in regenerative medicine. The purpose of this study was to evaluate the effect of interleukin…
