QEL-005: CD19 CAR-Regulatory T cell therapy, a novel approach for the treatment of complex immune mediated inflammatory diseases including Rheumatoid Arthritis and Systemic Sclerosis
Background/Purpose: Rheumatoid Arthritis (RA) and Systemic Sclerosis (SSc) are immune mediated inflammatory diseases (IMID) where a complex interplay of tissue and immune cell activation drives…Abstract Number: 0088 • ACR Convergence 2025
Imbalance of Inflammation-Regulating Microorganisms and Predicted Metabolomic Pathways Associates With Disease Evolution in Individuals At-Risk for Rheumatoid Arthritis
Background/Purpose: The mucosal origins hypothesis of RA proposes that immune responses to microorganisms at mucosal sites (e.g. intestine) lead to systemic inflammation and autoimmunity. Little…Abstract Number: 0094 • ACR Convergence 2025
Distinct immune-molecular signatures modulated ex vivo by JAK and TNF predict Rheumatoid Arthritis therapy outcomes in patients naïve to biologic and targeted synthetic DMARDs
Background/Purpose: Despite advances in rheumatoid arthritis (RA) treatment, 20–40% of patients do not respond to biologic or targeted synthetic DMARDs (b/tsDMARDs). Understanding each drug’s molecular…Abstract Number: 0089 • ACR Convergence 2025
Expansion of PD-1hi Tfh and Tph cells in the peripheral blood of seropositive clinically suspect arthralgia patients: association with progression to rheumatoid arthritis
Background/Purpose: Subjects with clinically suspect arthralgia (CSA) are at risk for developing rheumatoid arthritis (RA) and therapeutic interventions may prevent or delay progression. Still, a…Abstract Number: 0008 • ACR Convergence 2025
Characterization of S-1117, a novel pan-IgG protease engineered for reduced immunogenicity using the IMPACT platform
Background/Purpose: Pathogenic autoantibodies are key effectors of inflammation, promoting tissue damage in autoantibody-mediated diseases such as inflammatory myopathies, lupus nephritis, Sjogren’s syndrome, antiphospholipid syndrome, and…Abstract Number: 0084 • ACR Convergence 2025
Regulation of the same chemokine gene transcription by different histone lysine methyltransferases, MLL1 and MLL3, in rheumatoid arthritis synovial fibroblasts
Background/Purpose: Rheumatoid arthritis synovial fibroblasts (RASFs) produce various matrix metalloproteinases (MMPs), cytokines, and chemokines. Histone lysine methylation has been shown to play an important role…Abstract Number: 0092 • ACR Convergence 2025
SynovAI: A Revolutionary AI Framework for Enhanced Detection and Differentiation of Rheumatoid Arthritis, Osteoarthritis, and Spondyloarthritis via Advanced Ultrasound Imaging
Background/Purpose: Rheumatology musculoskeletal ultrasound (MSKUS) is a powerful technique to identify and differentiate arthritidies joint pathology, yet MSKUS is highly dependent on user experience. Techniques…Abstract Number: 0059 • ACR Convergence 2025
Formyl Peptide Receptor 1 (FPR1) Influences Arthritis Severity in a Sex- and Compartment-Specific Manner
Background/Purpose: Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease that disproportionately affects females over males (3:1). Although sex-based immune differences have been documented, particularly…Abstract Number: 0056 • ACR Convergence 2025
Repository Corticotropin Injection Reduces Inflammation and Bone Turnover Markers in the Murine CIA Model
Background/Purpose: Melanocortin receptor agonists, such as adrenocorticotropic hormone (ACTH), are anti-inflammatory with pleotropic functions. We aimed to evaluate the effects of a repository corticotropin injection…Abstract Number: 0082 • ACR Convergence 2025
IBI3011, a Humanized anti-IL1RAP Monoclonal Antibody, Inhibits IL1, IL33, IL36-driven Inflammation Pathway, and Attenuates Inflammation in Preclinical Inflammatory Disease Model
Background/Purpose: Interleukin 1 receptor accessory protein (IL1RAP) serves as a co-receptor that forms receptor complexes with IL1R1, ST2, and IL36R and mediates signaling pathways triggered…Abstract Number: 0037 • ACR Convergence 2025
A Proteomic Signature Containing TNF Receptor Superfamily Member 10A (TNFRSF10A) and Growth/Differentiation Factor 15 (GDF-15) Improves Prediction of All-Cause Mortality Among Individuals with Gout, Beyond Atherosclerotic Cardiovascular and Other Clinical Risk Factors
Background/Purpose: Gout affects >12 million US adults and is associated with premature all-cause and cardiovascular (CV) mortality which has failed to improve over recent decades,…
