Multi-Omic Profiling Of CD8+ T Cells In Axial Spondyloarthritis (axSpA) And Reactive Arthritis (ReA) Implicates Common Pathways
Background/Purpose: The strong clinical and genetic associations between axial spondyloarthritis (axSpA) and inflammatory bowel disease (IBD) underscore the pathogenic role of the gut-joint axis. We…Abstract Number: 0811 • ACR Convergence 2025
SSc Skin Cell Atlas: a Scalable Web Portal for scRNA-Seq Analysis
Background/Purpose: Despite the recent popularity and utility of modern high-resolution sequencing technologies, leveraging publicly available single-cell studies remains hampered by the need for substantial computational…Abstract Number: 1725 • ACR Convergence 2025
Functional NOTCH4 Variants Drive Vasculopathy and Fibrosis in Systemic Sclerosis.
Background/Purpose: Systemic sclerosis (SSc) is characterized by vasculopathy, progressive fibrosis of skin and internal organs, and autoimmunity. Notably, African American (AA) patients with SSc exhibit…Abstract Number: 0774 • ACR Convergence 2025
Longitudinal peripheral blood multi-omic profiling in at-risk individuals uncovers immune signatures and predictive models for future rheumatoid arthritis conversion
Background/Purpose: Seropositive rheumatoid arthritis (RA) has an at-risk stage identifiable by elevations of antibodies to cyclic citrullinated peptide (CCP). Identifying the immunologic factors that distinguish…Abstract Number: 1699 • ACR Convergence 2025
Protein-coding Somatic Genetic Variation in Lymphocytes in Systemic Lupus Erythematosus
Background/Purpose: The genetic and environmental factors underlying pathogenesis of systemic lupus erythematosus (SLE) are incompletely resolved. While inherited genetic variation has been extensively queried in…Abstract Number: 0104 • ACR Convergence 2025
Dissecting the Genetic and Functional Association of CARD9 with Axial Spondyloarthritis
Background/Purpose: Axial spondyloarthritis (axSpA) is a chronic immune-mediated inflammatory disease with strong genetic predisposition, driven by HLA-B27 and over 100 additional loci identified by genome-wide…Abstract Number: 2700 • ACR Convergence 2025
Neutrophil Transcriptomics and Maturation Pathways in VEXAS Syndrome
Background/Purpose: VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a severe adult-onset inflammatory disease caused by somatic mutations of the ubiquitin-like modifier activating enzyme…Abstract Number: 1700 • ACR Convergence 2025
Altered Gene Expression In Male SLE Is Mapped To a Male-Specific Y Chromosome Locus Associated with Microdeletions
Background/Purpose: SLE occurs more frequently in females than males, with relative prevalence 9-10:1. While the impact of hormones on immune function may contribute to the…Abstract Number: 0071 • ACR Convergence 2025
Unravelling Transcriptomic Landscapes in Rheumatoid Arthritis and Systemic Lupus Erythematosus: Shared and Unique Molecular Signatures related to relevant clinical features.
Background/Purpose: This study aimed to identify shared and distinct gene and protein expression profiles associated with clinical features in rheumatoid arthritis (RA), systemic lupus erythematosus…Abstract Number: 2683 • ACR Convergence 2025
Association of Genetic Risk for Pain Intensity with Longitudinal Disease Activity in Rheumatoid Arthritis
Background/Purpose: Guidelines recommend the use of composite scores to evaluate disease activity in RA and inform a treat-to-target approach. It is recognised that patient-reported components…Abstract Number: 1696 • ACR Convergence 2025
A multi-omics resource of B cell activation reveals genetic mechanisms for autoimmune diseases
Background/Purpose: Most genetic variants that confer risk of complex autoimmune diseases affect gene regulation in specific cell types. Their target genes and focus cell types…Abstract Number: 0046 • ACR Convergence 2025
Association of Genetic Variation in XIST and FTX with Susceptibility to Female-Biased Systemic Autoimmune Disease
Background/Purpose: The mechanisms underlying female sex bias in autoimmune diseases remain unclear. Recent work has suggested that impaired maintenance of X-chromosome inactivation (XCI) in female…Abstract Number: 2602 • ACR Convergence 2025
Cellular and molecular fine mapping in single-cell data pinpoints new immunopathology of systemic lupus erythematosus
Background/Purpose: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with unknown etiology. While we previously identified key gene signatures of SLE using bulk RNA-seq…Abstract Number: 1653 • ACR Convergence 2025
Gut-joint lymphocyte trafficking functions to regulate systemic immunity
Background/Purpose: The gut-joint and mucosal origins hypotheses postulate that immune alterations in mucosal sites may precede and impact the development of rheumatoid arthritis and spondyloarthritis.…Abstract Number: 0045 • ACR Convergence 2025
Genetic regulators of corticosteroid response in hepatic and adipose tissue and risk of adverse metabolic outcomes in patients with rheumatoid arthritis initiating glucocorticoids.
Background/Purpose: Previous studies identified single nucleotide polymorphisms (SNPs) that affect hepatocyte and adipocyte response to glucocorticoids (GCs). We aimed to determine if these candidate SNPs…
