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…Abstract Number: 0727 • ACR Convergence 2023
A Novel Active Pemphigus Vulgaris Mouse Model Induced by Immunization with TLR Ligand Adjuvanted Recombinant Desmoglein 3 Protein Vaccine
Background/Purpose: Pemphigus vulgaris (PV) is an autoimmune bullous skin disease mediated by desmoglein-3 (Dsg3) specific auto-antibody present in skin and mucosae. The binding of pathogenic…Abstract Number: 079 • 2023 Pediatric Rheumatology Symposium
Dynamics of Neutrophil Activation in Repeated TLR-9-Induced Mouse Model of Macrophage Activation Syndrome
Background/Purpose: Macrophage activation syndrome (MAS) is a life-threatening complication of rheumatic diseases including systemic juvenile idiopathic arthritis (SJIA). SJIA shows prominent neutrophil activation with expansion…Abstract Number: L10 • ACR Convergence 2022
Efgartigimod Prevents Necrosis and Allows for Muscle Fiber Regeneration in a Humanized Mouse Model of Immune-mediated Necrotizing Myopathy (IMNM)
Background/Purpose: Immune-mediated necrotizing myopathy (IMNM) is a severe form of myositis characterized by muscle weakness and elevated creatine kinase levels in serum. The most frequent…Abstract Number: 0568 • ACR Convergence 2022
The Absence of Blk Leads to Increased Inflammation in a Murine Model of Kawasaki Disease
Background/Purpose: Kawasaki Disease (KD) is the leading cause of acquired heart disease in children in developed countries characterized by inflammation of the coronary arteries leading…Abstract Number: 0580 • ACR Convergence 2022
18F-FDG PET-MR Characterization of Aortitis in the IL1rn-/- Mouse Model of Giant-Cell Arteritis

Mapping Spondyloarthritis Susceptibility Loci in B10.RIII Mice
Background/Purpose: Overexpression of IL-23 using IL-23 minicircle DNA in B10.RIII mice results in the development of a spondyloarthritis-like disease. B10.RIII (B10.RIII-H2r H2-T18b/(71NS)SnJ) is a major…Abstract Number: 1178 • ACR Convergence 2022
Key Features of Human Fibrosing Interstitial Lung Disease Are Captured in a Preclinical Mouse Model upon Repetitive, but Not Single Intratracheal Bleomycin Dosing
