CXCL6 Synthesized by Proximal Tubule Cells May Promote Fibrosis in Lupus Nephritis
Background/Purpose: Detection of urinary CXCL6, a member of the IL-8 chemokine family, has been linked to CKD and is a proposed marker of chronic damage…Abstract Number: 2292 • ACR Convergence 2024
Fibroblasts with High Expression of CD74 Promote Lymphocytes Infiltration in Salivary Gland in Sjӧgren’s Disease
Background/Purpose: Sjӧgren's disease (SjD) is characterized by persistent focal infiltration of B- and T lymphocytes in the exocrine gland, mainly salivary gland. Though it is…Abstract Number: 2474 • ACR Convergence 2024
High-throughput Screening Identifies Specific Molecular Markers for ILD in Patients with Rheumatic Diseases
Background/Purpose: Molecular expression patterns of lung tissue across rheumatic musculoskeletal diseases (RMDs) have not been extensively studied. Lung sampling is invasive and not always practical…Abstract Number: 2502 • ACR Convergence 2024
Characterization of the Tissue Fibroblast Repertoire in IgG4-Related Ophthalmic Disease
Background/Purpose: IgG4-related disease (IgG4-RD) is a systemic fibroinflammatory condition characterized by tissue infiltration with IgG4+ plasma cells. Fibrosis in the target organs is one of…Abstract Number: 2539 • ACR Convergence 2024
Telocytes Integrated into Mast Cells and Joint-Draining Lymphatic Vessels Potentially Regulate Lymphatic Clearance
Background/Purpose: Rheumatoid arthritis (RA) patients and TNF-transgenic mice have lymphatic dysfunction (1). Recently, we showed mast cells involvement, as genetic ablation and drug inhibition decreased…Abstract Number: 2550 • ACR Convergence 2024
Infiltrating and Resident Macrophages in Lupus Nephritis: Scar Associated Macrophage Phagocytic Dysfunction and Fibroblast Activation
Background/Purpose: Lupus nephritis (LN) is driven by a heterogeneous population of renal macrophages. We have previously reported that the renal macrophage subpopulations are similar in…Abstract Number: 0054 • ACR Convergence 2024
Supernatants from Macrophages Stimulated with Citrullinated and MAA-Modified Fibrinogen Contain PDGF-BB and TGF-b and Upregulate Fibrotic Markers in Human Lung Fibroblasts
Background/Purpose: Lung tissues from patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) have greater levels of malondialdehyde-acetaldehyde adducts (MAA) that co-localize with citrullinated (CIT) and…Abstract Number: 0061 • ACR Convergence 2024
Comparative Transcriptional Profiling of IPF and RA-ILD Lung Tissue Demonstrates Both Overlapping and Distinct Cell-specific Signaling Pathways
Background/Purpose: Transcriptional profiling represents a powerful tool for deciphering disease-relevant pathways and deriving functional biomarkers. Given the shared demographic, genetic, and clinico-epidemiologic features between rheumatoid…Abstract Number: 0062 • ACR Convergence 2024
Pro-Fibrotic Effects of Malondialdehyde-Acetaldehyde-Adducted and/or Citrullinated Proteins on Macrophages and Human Lung Fibroblasts
Background/Purpose: Clinically evident rheumatoid arthritis-associated interstitial lung disease (RA-ILD) affects approximately 10-15% of patients with rheumatoid arthritis (RA) and accounts for the most overrepresented cause…Abstract Number: 0771 • ACR Convergence 2024
Arid5b Controls Pathologic Inflammatory versus Invasive Fibroblast Behavior
Background/Purpose: Synovial fibroblasts assume both inflammatory and tissue invasive roles in rheumatoid arthritis (RA). Recent studies have shown that these inflammatory and invasive functions are…Abstract Number: 0969 • ACR Convergence 2024
Role and Mechanism of the Wnt3a-FZD5 Pathway in Regulating the Transformed Intermediate State of Alveolar Epithelial Cells Involved in Pulmonary Fibrosis in Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is a diffuse connective tissue disease associated with multi-system and multi-organ tissue damage. The transformation of different precursor cells to myofibroblasts…Abstract Number: 0972 • ACR Convergence 2024
Downregulated Fli1 in Scleroderma Myeloid Cells Contributes to Cardiac Fibrosis via a Galectin-3/mTOR Dependent Pathway
Background/Purpose: Cardiac fibrosis is a common complication in Systemic sclerosis (SSc), but the pathogenesis is largely unknown. We have previously shown that monocytes isolated from…Abstract Number: 1686 • ACR Convergence 2024
Urine Proteomics in Class II Lupus Nephritis Reveals Immune Activation and Pro-Fibrotic Signatures
Background/Purpose: Lupus nephritis (LN) is a pathologically diverse autoimmune disease that can lead to end-stage kidney disease and mortality. Although Class II LN is considered…Abstract Number: 1770 • ACR Convergence 2024
Assessing S100A4 and Myofibroblast Phenotypes in the Pathogenesis of Cardiac and Cutaneous Neonatal Lupus
Background/Purpose: Neonatal lupus (NL), driven by fetal exposure to maternal anti-SSA/Ro autoantibodies, typically results in permanent cardiac manifestations in utero and/or a transient rash postnatally.…Abstract Number: 0029 • ACR Convergence 2023
Post-translationally Modified Fibrinogen Activated Macrophages Drive the Expression of Fibrotic Genes in Human Lung Fibroblasts
Background/Purpose: Cellular interactions between alveolar macrophages (MΦ) and human lung fibroblasts (HLFs) contribute to excessive pro-inflammatory and pro-fibrotic responses in rheumatoid arthritis interstitial lung disease…
