Tape Stripping Expression Signatures Identify Biologically Unique Juvenile Dermatomyositis Patient Subgroup Characterized by Increased Mitochondrial Dysfunction
Background/Purpose: Skin inflammation in juvenile dermatomyositis (JDM) can signal disease onset or flare and prevent complete disease remission. The study of cutaneous expression signatures holds…Abstract Number: 1771 • ACR Convergence 2023
Role of Periostin in the Pathophysiology and Accurate Diagnosis of Interstitial Lung Disease Associated with Autoimmune Diseases
Background/Purpose: Periostin is an extracellular matrix protein that contributes to the development and repair of lung tissue [1]. Previous works have described periostin as a…Abstract Number: 1757 • ACR Convergence 2023
Quantitative Assessment of Synovial Vascularity Using Power Doppler Index in Rheumatoid Arthritis and Psoriatic Arthritis Patients with High Disease Activity
Background/Purpose: Usefulness of quantitative assessment of synovial vascularity in ultrasound (US) imaging in patients with active RA and PsA (peripheral arthritis). Additionally the assessment of…Abstract Number: 1749 • ACR Convergence 2023
Fatty Acid Synthase Is a Critical Repressor of Ferroptosis in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is a systemic autoimmune disease with synovial inflammation as the main pathological feature, and can eventually lead to irreversible joint or…Abstract Number: 1703 • ACR Convergence 2023
Increased Mortality and Cardiovascular Events in Male Patients with Systemic Sclerosis: Left Ventricular Global Longitudinal Strain as Possible Screening Tool
Background/Purpose: Systemic sclerosis (SSc) is less frequent in males, but the risk of severe outcomes is higher in males than in females(1). Seven to 30%…Abstract Number: 1759 • ACR Convergence 2023
Runx1 Is a Key Transcription Factor That Drives Synovial Fibroblast Pathogenicity in Rheumatoid Arthritis
Background/Purpose: Fibroblasts are key effector cells in rheumatoid arthritis (RA) underpinning joint inflammation and damage. Synovial tissue fibroblasts are heterogenous and acquire pathogenic cell states…Abstract Number: 1713 • ACR Convergence 2023
Prevention of Arthritis Development by Mechanical Unloading Through Inhibition of CCL2 and YAP-mediated Inflammation in the Rat Adjuvant-induced Arthritis Model
Background/Purpose: Rheumatoid arthritis (RA) is the most common chronic inflammatory rheumatic disease, characterized by synovitis associated with progressive bone loss and joint degradation. The adjuvant-induced…Abstract Number: 1741 • ACR Convergence 2023
The Occurrence and Phenotype of Autoreactive T Cells in the At-Risk Phase of Rheumatoid Arthritis
Background/Purpose: CD4+ T cells recognizing citrullinated epitopes are present in peripheral blood of anti-citrulline protein antibody (ACPA) positive rheumatoid arthritis (RA) patients at time of…Abstract Number: 1776 • ACR Convergence 2023
Macrophage Migration Inhibitory Factor May Help Maintain Tight Junctions in the Gut by Enhancing Occludin Expression
Background/Purpose: Axial Spondyloarthritis (AxSpA) is a chronic inflammatory disease with multifactorial origins, primarily affecting the musculoskeletal system. Gut inflammation is seen in the majority of…Abstract Number: 1769 • ACR Convergence 2023
TNF-Stimulated Production of IL-15 by Fibroblast-Like Synoviocytes Mediates Human Resident Memory T Cells Development in Synovial Organoid Model
Background/Purpose: Rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) are chronic autoimmune diseases that tend to flare repeatedly in the same joints, displaying joint-specific memory.…Abstract Number: 1747 • ACR Convergence 2023
A Newly Described Cytokine interleukin-40 Is Increased in the Serum of Individuals At-risk of Rheumatoid Arthritis and Induces an Inflammatory Response in Mononuclear Cells
Background/Purpose: Interleukin-40 (IL-40) is a newly described cytokine related to malignancies and immunity function. We have previously shown that IL-40 is up-regulated in early stages…Abstract Number: 1855 • ACR Convergence 2023
Using a Whole-population Approach to Help Design More Effective and Efficient Healthcare Services for People with Fibromyalgia
Background/Purpose: A large body of evidence has informed, internationally, management recommendations for people with fibromyalgia. However there are very few studies which have examined how…
