Cytokines Regulate the Fibrotic Response of Growth Factors in Joint Fibroblast-like Synoviocytes
Background/Purpose: Rheumatoid arthritis (RA) and osteoarthritis (OA) are characterized by inflammation, joint swelling, stiffness, and pain. A fibroid phenotype has been identified in RA, where…Abstract Number: 0863 • ACR Convergence 2023
Phenotype and Energy Metabolism Differ Between Osteoarthritic Chondrocytes from Male Compared to Female Patients
Background/Purpose: Changes in chondrocyte phenotype and energy metabolism occur in osteoarthritis (OA). The prevalence of OA is higher in females compared to males however whether…Abstract Number: 0892 • ACR Convergence 2023
Single-Cell RNA Sequencing Reveals Keratinocytes and Fibroblasts Drive Hippo and TGFb Dysregulation and Fibrosis in Epidermal Overexpression of VGLL3 in Cutaneous Lupus
Background/Purpose: Fibrosis is characterized by collagen deposition, fibro/myofibroblast (MYOFB) accumulation, and extracellular matrix remodeling. In some subtypes of cutaneous lupus erythematosus (CLE), particularly discoid lupus…Abstract Number: 0952 • ACR Convergence 2023
Unraveling the Role of MiR-181 in Skin Fibrosis Pathogenesis by Targeting NUDT21
Background/Purpose: Nudix Hydrolase 21 (NUDT21, also known as CFIm25) is a master regulator of alternative polyadenylation. Previous studies have revealed that NUDT21 is significantly decreased…Abstract Number: 0954 • ACR Convergence 2023
Non-canonical WNTA Promotes Cytoskeletal Rearrangement and Integrin Alpha V Clustering via JNK and ROCK to Control the Activation of Latent TGFβ
Background/Purpose: Systemic sclerosis (SSc) is a chronic autoimmune disorder with vasculopathy, inflammation, and fibrosis of the skin and organs. Fibrosis is caused by the abnormal…Abstract Number: 0029 • ACR Convergence 2022
Characterizing the Anti-fibrotic Effect of Tofacitinib in TGF-β Stimulated Fibroblast-like Synoviocytes from Patients with OA
Background/Purpose: Many osteoarthritis (OA) patients develop fibrosis of the synovial membrane leading to joint swelling, stiffness, and pain. Synovial fibroblasts activated in the synovial membrane…Abstract Number: 0620 • ACR Convergence 2022
Neovascularization Is Altered by Rheumatoid Arthritis Synovial Fibroblasts and Canstatin in Vitro and in Vivo
Background/Purpose: In the pathogenesis of rheumatoid arthritis (RA), neovascularization is increased in the activated and inflamed synovium. RA synovial fibroblasts (RASF) are key players in…Abstract Number: 1215 • ACR Convergence 2022
Identifying a Pain Signature in Classical Ehlers-Danlos Syndrome: Preliminary Results from Questionnaires and Experimental Pain Testing
Background/Purpose: Chronic pain is one of the most common complaints of individuals with Ehlers-Danlos syndrome (EDS) and the effects of the existing therapeutical modalities are…Abstract Number: 1610 • ACR Convergence 2022
Are Serological Protease-mediated Peptides of Tissue Remodeling and Inflammation the New Disease Activity Biomarkers in Psoriatic Arthritis Patients?
Background/Purpose: Inflammatory and degenerative processes in the joint tissues are hallmarks of patients with psoriatic arthritis (PsA). Here, proteases play a major role in remodeling…Abstract Number: 1986 • ACR Convergence 2022
Early-stage Rheumatoid Arthritis Patients with High Levels of Type III Collagen Are Less Likely to Respond to Anti-IL6R Treatment
Background/Purpose: Rheumatoid arthritis (RA) is a chronic, autoimmune disease, which normally is characterized by inflammation and thickening of the synovial membrane leading to swollen and…Abstract Number: 2044 • ACR Convergence 2022
Abnormalities of Extracellular Matrix Modeling Gene Expression in Salivary Gland Epithelial Cells of Patients with Sjögren’s Syndrome
Background/Purpose: Salivary gland epithelial cells (SGECs) are not only the target of autoimmunity in primary Sjögren's syndrome (pSS). SGECs may interact with lymphocytes and therefore…Abstract Number: 2129 • ACR Convergence 2022
Serum Extracellular Matrix Biomarkers Identify Response to Guselkumab in Psoriatic Arthritis; Post-hoc Analysis from a Phase 3, Randomized, Double-blind, Placebo-controlled Study Through 2 Years
Background/Purpose: Psoriatic arthritis (PsA) is a progressive, joint-degenerative inflammatory disease with cartilage destruction, bone erosion and growth, and synovitis. Extracellular matrix (ECM) remodeling is also…
