Efficacy and Safety of Telitacicept in Patients with Sjögren’s Disease: Results from a Multicenter, Randomized, Double-blind, Placebo-controlled, Phase 3 Clinical Study
Background/Purpose: Sjögren's disease (SjD) is a chronic autoimmune disease whose pathogenesis is associated with aberrant activation of B-lymphocytes. Telitacicept, a novel fusion protein, dually targets and…Abstract Number: 0039 • ACR Convergence 2025
Hemophagocytic Lymphohistiocytosis Gene Variants in Severe COVID-19 Cytokine Storm Syndrome
Background/Purpose: Severe COVID-19 infection resulting in hospitalization shares features with frequently fatal cytokine storm syndromes (CSS), such as hemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome…Abstract Number: 0906 • ACR Convergence 2025
Preclinical Characterization of IBI3034, an TACI and BCMA Chimeric Fc Fusion Protein, that Potently Modulates B Lymphocytes and Serum Immunoglobulin for the Treatment of B cell Related Autoimmune Disease
Background/Purpose: Dysregulated B-cell activation plays a pivotal role in the pathogenesis of various autoimmune diseases. B-cell activating factor (BAFF) and a proliferation-inducing ligand (APRIL) are…Abstract Number: 0934 • ACR Convergence 2025
The Use Of Preclinical Models To Understand Drivers Of Lupus Pathogenesis
Background/Purpose: Systemic Lupus Erythematosus (SLE) is a chronic, multisystem autoimmune disease with a prevalence of 1.4-15.13/100,000 adults globally. SLE is highly heterogenous and can involve…Abstract Number: 1119 • ACR Convergence 2025
Microbial activation of cytotoxic CD8⁺ T cells promotes skin immune-related adverse events in patients treated with immune checkpoint inhibitors
Background/Purpose: Immune checkpoint inhibitors (ICIs) have transformed cancer therapy, but their use is often limited by immune-related adverse events (irAEs), particularly in barrier tissues such…Abstract Number: 1723 • ACR Convergence 2025
Impaired Maintenance of X-Chromosome Inactivation in B Cells, But Not T Cells, Exacerbates Interferon-Driven Systemic Autoimmunity
Background/Purpose: Many systemic autoimmune diseases associated with chronic type 1 interferon (IFN) signaling, including SLE, SjD, and SSc, preferentially afflict females. The biological basis of…Abstract Number: 1759 • ACR Convergence 2025
Role of a pathogenic bacterial factor produced by a human gut pathobiont in inducing platelet activation and thrombo-inflammation.
Background/Purpose: SLE is an autoimmune disease that causes progressive multi-organ damage, leading to renal injury, or lupus nephritis (LN), in half of patients. Despite treatment,…Abstract Number: 1819 • ACR Convergence 2025
Spatial Transcriptomic Profiling Reveals Interferon Activation and CD8⁺ T Cell Dominance in Systemic Juvenile Idiopathic Arthritis-Macrophage Activation Syndrome Liver Inflammation
Background/Purpose: Systemic juvenile idiopathic arthritis (SJIA) with macrophage activation syndrome (MAS) involves severe systemic inflammation and hepatocellular injury. Our prior histopathology studies showed increased CD8⁺…Abstract Number: 1829 • ACR Convergence 2025
Multiomic Investigation of Juvenile Idiopathic Arthritis Synovium Reveals Immune Cell Heterogeneity
Background/Purpose: Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory rheumatic disease of childhood, affecting 1:1,000 children worldwide. The hallmark of JIA is immune-mediated…Abstract Number: 2664 • ACR Convergence 2025
Neutrophil-to-Lymphocyte Ratio (NLR) as a Clinically Accessible Marker for Interferon Signatures in Autoimmune Diseases
Background/Purpose: Interferons (IFNs) play critical roles in systemic autoimmune diseases, particularly systemic lupus erythematosus (SLE), where heightened type I IFN signaling is a hallmark. Elevated…Abstract Number: 2494 • ACR Convergence 2025
Abatacept Reduces CD319+ (SLAM-F7) Cytotoxic T Cells and Cytokine Production in Systemic Sclerosis
Background/Purpose: While the ASSET clinical trial (placebo-controlled blinded trial of abatacept) in patients with diffuse cutaneous systemic sclerosis (dcSSc) did not meet its primary endpoint…Abstract Number: 0389 • ACR Convergence 2024
Histopathological Features of Liver Tissue Biopsies in SJIA Patients with and Without Clinical Macrophage Activation Syndrome
Background/Purpose: Systemic Juvenile Idiopathic Arthritis (SJIA) can present with or without Macrophage Activation Syndrome (MAS), a severe, potentially life-threatening complication. Liver tissue injury is commonly…Abstract Number: 1765 • ACR Convergence 2024
CD8+ T Cells and Monocytes from Children with Macrophage Activation Syndrome Demonstrate Specific Transcriptional Changes Consistent with T Cell Activation and Expansion of Monocytes Shaped by Interferon and TLR Signaling
Background/Purpose: Macrophage activation syndrome (MAS), a form of secondary hemophagocytic lymphohistiocytosis (sHLH), is a potentially fatal complication of rheumatic diseases. MAS is characterized by a…Abstract Number: 1839 • ACR Convergence 2024
PPP2R3C Overexpression Suppresses TCR -mediated CD4+ T Cell Abnormal Activation in Systemic Lupus Erythematosus via JNK and AKT-mTOR Pathways
Background/Purpose: Systemic Lupus Erythematosus (SLE) is distinguished by immune system dysfunction, leading to heightened activation of T and B cells. This increased activity leads to…
