Neutrophils in Patients with Systemic Lupus Erythematosus Show Pronounced Inflammatory Signals
Background/Purpose: IFN response, plasmablasts and neutrophils are three hallmarks of systemic lupus erythematosus (SLE). Studies showed that the netting neutrophils stimulated plasmacytoid dendritic cells to…Abstract Number: 2517 • ACR Convergence 2023
The Relationship Between the NETosis Findings and Disease Activity in Behcet Disease
Background/Purpose: Behcet disease (BD) is a multisystemic inflammatory disease of unknown etiology. BD has been classified among the neutrophilic dermatosis, and neutrophil extracellular traps (NETs)…Abstract Number: 1339 • ACR Convergence 2023
Neutrophil Activation and Formation of Neutrophil Extracellular Traps Are Associated with Response to Abatacept in Patients with Moderate to Severe Rheumatoid Arthritis
Background/Purpose: Neutrophil activation and formation of neutrophil extracellular traps (NETs) have been implicated in the pathogenesis of rheumatoid arthritis (RA). Calprotectin, a neutrophil activation marker,…Abstract Number: 1363 • ACR Convergence 2023
Plasma Neutrophil Extracellular Trap Remnant Levels Are Lower in Premenopausal Healthy Women Using Oral Contraceptive Pills
Background/Purpose: Women develop RA 3 times more often than men, and several risk factors for RA are female specific. Prior studies demonstrate an association between…Abstract Number: 0044 • ACR Convergence 2023
Aberrant Mevalonate Metabolite Farnesyl Pyrophosphate-Induced Neutrophil Hyperactivation in Behçet’s Disease Pathogenesis
Background/Purpose: Behçet’s disease (BD) is a chronic vasculitis characterized by polymorphonuclear neutrophils (PMNs) hyperactivation with unknown etiology. The over-productions of neutrophil extracellular traps (NETs) and…Abstract Number: 1585 • ACR Convergence 2023
Defining Neutrophil-Mediated Renal Damage Triggered by Ultraviolet (UV) Skin Exposure
Background/Purpose: Lupus (SLE) is one of the leading causes of death in young women in the United States. Roughly ~80% of SLE patients experience sensitivity…Abstract Number: 0045 • ACR Convergence 2023
Discovery and Characterization of a Selective, Orally Bioavailable PAD4 Inhibitor to Target NETs Driven Autoimmune and Inflammatory Diseases
Background/Purpose: Protein arginine deiminases (PAD) 4 is an enzyme that catalyzes the conversion of protein-embedded arginine to citrulline. It is essential for neutrophil extracellular traps…Abstract Number: 1603 • ACR Convergence 2023
Infection-Associated Antiphospholipid Antibodies and Their Potential Role in Sepsis Outcomes
Background/Purpose: Antiphospholipid syndrome (APS) is an acquired autoimmune thrombophilia characterized by circulating antiphospholipid antibodies (aPL). While the association between aPL and infection has long been…Abstract Number: 0050 • ACR Convergence 2023
Anti-Citrullinated Histone Antibody CIT-013, a Dual Action Therapeutic for Neutrophil Extracellular Trap Associated Autoimmune Disease
Background/Purpose: Neutrophil extracellular traps (NETs) contribute to the pathophysiology of multiple inflammatory and autoimmune diseases (Chirivi et al., 2021; DOI: 10.1038/s41423-020-0381-3). Targeting the NETosis pathway…Abstract Number: 1705 • ACR Convergence 2023
Reduced DNASE1L3 Activity and Increased Anti-NET Protective Antibodies Contributes to Accumulation of Neutrophil Extracellular Traps in Pediatric SLE Patients
Background/Purpose: Pediatric systemic lupus erythematosus (pSLE) is a multisystemic chronic autoimmune disease with high renal involvement. In SLE, neutrophil extracellular traps (NETs) are considered a…Abstract Number: 0060 • ACR Convergence 2023
Serpin B1 Modulation of Immune Complex-Mediated Neutrophil Activation and NET-formation Requires Its Chymotrypsin-like Inhibitory Activity
Background/Purpose: Autoantibody-antigen complex-driven formation of neutrophil extracellular traps (NETs) is a major contributing factor to the pathophysiology and clinical manifestations of many different autoimmune diseases…Abstract Number: 1735 • ACR Convergence 2023
An Unorthodox HLA-DRhiCD15+ ‘Hybrid’ Population in Rheumatoid Arthritis Characterized Using Spectral Cytometry
Background/Purpose: A variant of HLA-DR confers the strongest genetic risk for rheumatoid arthritis (RA) suggesting that DRhi cells are important in RA. We previously found…Abstract Number: 0101 • ACR Convergence 2023
Non-Criteria Antiphospholipid Antibodies and Calprotectin as Potential Biomarkers in Pediatric Antiphospholipid Syndrome
Background/Purpose: While classification criteria for pediatric APS are not yet available, recent research suggests pediatric APS patients are unique, and many present with extra-criteria manifestations…Abstract Number: 1765 • ACR Convergence 2023
Persistent Cigarette Smoking Is Associated with Rheumatoid Arthritis Onset and Neutrophil Activation in a Prospective Study of At-risk First-Degree Relatives
Background/Purpose: Cigarette smoking (CS) is a major environmental risk factor for the development of Rheumatoid Arthritis (RA), and is associated with the development of RA…Abstract Number: 0110 • ACR Convergence 2023
Neutrophil Extracellular Traps as Mediators of Antiphospholipid Antibody-Induced Trophoblast Dysfunction and Fetal Loss
Background/Purpose: Antiphospholipid antibodies (aPL) induce obstetric complications associated with placental insufficiency by promoting trophoblast dysfunction and inflammation at the maternal-fetal interface. Neutrophils have been found…
