LMPTP Drives Fibrosis in Systemic Sclerosis via TGF-beta Signaling Activation
Background/Purpose: The identification of effective and safe anti-fibrotic agents is a critical unmet need in systemic sclerosis (SSc). Although fibrosis in SSc is driven by…Abstract Number: 0963 • ACR Convergence 2025
Increased expression of M2 pro-fibrotic markers in circulating monocytes and cultured monocyte-derived macrophages from systemic sclerosis patients with progressive interstitial lung disease (ILD)
Background/Purpose: In the complex pathogenesis of systemic sclerosis (SSc), macrophages are mainly involved in mechanism of progressive tissue fibrosis of skin and internal organs, particularly…Abstract Number: 0961 • ACR Convergence 2025
Retinoic acid-related orphan receptor-α: A novel upstream regulator of Hippo signaling and potential therapeutic target in fibrosis
Background/Purpose: Retinoic acid-related orphan receptor-α (RORα) is a nuclear transcription factor implicated in immune regulation, circadian rhythm, and metabolism. However, its role in fibrotic diseases…Abstract Number: 0679 • ACR Convergence 2025
Inhibition of TGFb3 in Systemic Sclerosis Patients Does Not Result in TGFb Pathway Modulation in Skin Biopsies or Circulation
Background/Purpose: There are 3 isoforms of Transforming Growth Factor Beta (TGFb), a cytokine frequently upregulated in fibrosis. Chronic targeting of TGFb1 and TGFb2 for fibrotic…Abstract Number: 1873 • ACR Convergence 2025
TGF-β-Driven Mitochondrial Stress Activates cGAS-STING Signalling via Impaired Mitophagy in Systemic Sclerosis Endothelial Cells
Background/Purpose: Emerging evidence implicates mitochondrial dysfunction as a contributor to tissue fibrosis in systemic sclerosis (SSc) (1). Endothelial cells, which are a key player in…Abstract Number: 1831 • ACR Convergence 2025
Distinct Proteomic Signature Predicts Post-MMF Withdrawal Flares in Systemic Lupus Erythematosus Patients
Background/Purpose: : Systemic Lupus Erythematosus (SLE) follows a characteristic relapsing-remitting course with unpredictable flares interspersed with periods of relative quiescence. Mycophenolate mofetil (MMF) has emerged…Abstract Number: 1778 • ACR Convergence 2025
Towards an Earlier and Accurate Diagnosis of Connective Tissue Disease-related Interstitial Lung Disease: TGFB Isoform Genes as Upcoming Biomarkers
Background/Purpose: Interstitial lung disease (ILD) is one of the leading cause of mortality in patients with connective tissue diseases (CTDs) [1]. The onset of CTD-ILD…Abstract Number: 1654 • ACR Convergence 2025
A Dual Inhibitor of TAK1 and MAP4K2, NG25, Suppresses Cytokine-Driven Inflammation in Juvenile Idiopathic Arthritis Synovial Fibroblasts
Background/Purpose: Chronic synovitis is a hallmark of juvenile idiopathic arthritis (JIA), and synovial fibroblasts are major perpetrators of inflammation and tissue destruction. Thus, we tested…Abstract Number: 0977 • ACR Convergence 2025
The nuclear receptor DAX1 regulates WNT/β-catenin signaling to promote fibroblast activation and skin fibrosis in systemic sclerosis
Background/Purpose: Nuclear receptors are a family of transcription factors that is commonly targeted for therapeutic intervention. Dosage-sensitive sex reversal adrenal hypoplasia congenital critical region on…Abstract Number: 1663 • ACR Convergence 2024
Notch—mediated Fibrogenic Activation Is a Spatial Determinant of RA Treatment Response
Background/Purpose: In RA, poor treatment response has been linked to a fibroid synovial tissue phenotype, characterized by lack of immune cell infiltration and an expansion…Abstract Number: 1920 • ACR Convergence 2024
Admixture Mapping and Gene-Based Analysis Identifies Rare Variants in Genes in the IL-13 and TGFβ Signaling Pathways in African Americans with Systemic Sclerosis
Background/Purpose: There are significant racial disparities in systemic sclerosis (SSc), with an increased disease burden and worse outcomes among African American (AA) individuals. Reasons for…Abstract Number: 2595 • ACR Convergence 2024
TGF-β Activated Kinase 1 (TAK1) Inhibition Suppresses Synovial Inflammation and Tissue Destruction Mediated by Activated Juvenile Idiopathic Arthritis Synovial Fibroblasts
Background/Purpose: Synovial inflammation is a common manifestation of juvenile idiopathic arthritis (JIA), often accompanied by debilitating synovial hyperplasia. The current study aims to characterize the…Abstract Number: 0012 • ACR Convergence 2023
Immune-cell Derived Cytokines Synergistically Interact to Drive Synovial Fibroblast Invasive Function and Metabolic Capacity
Background/Purpose: Rheumatoid Arthritis (RA) and Psoriatic Arthritis (PsA) encompass two of the most common forms of Inflammatory Arthritis. While common pathogenic mechanisms are involved in…Abstract Number: 0942 • ACR Convergence 2023
G Protein-coupled Receptor Kinase 5 in Fibrotic Tissue Remodeling
Background/Purpose: G-protein coupled receptor kinase 5, GRK5, is a central regulator of G protein-coupled receptors (GPCRs), a vast family of cell surface receptors involved in…Abstract Number: 0945 • ACR Convergence 2023
The Nuclear Receptor TR4 Orchestrates Cytoskeletal Organization in a Gα12/ROCK-dependent Manner to Promote Myofibroblast Differentiation and Tissue Fibrosis in Systemic Sclerosis
