Differential Induction of Anti-Muscarinic Type-3-Receptor Antibodies by Immunization with 4-Hydroxy-2-nonenal-Modified Ro60 in BALB/c Mice
Background/Purpose: Sjögren's Disease is an autoimmune condition in which patients exhibit decreased salivary/lacrimal gland function and express autoantibodies that target the 60k molecular weight Ro…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…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: 0803 • ACR Convergence 2023
IL10 Inhibits Toll-like Receptor-9-induced T Cell Receptor-mediated T Cell Activation in Macrophage Activation Syndrome
Background/Purpose: Macrophage activation syndrome (MAS) is a potentially fatal complication of systemic juvenile idiopathic arthritis (sJIA). Gene expression pathway analyses have identified altered Toll-like receptor…Abstract Number: 0870 • ACR Convergence 2023
Targeting Peroxisome Proliferator-Activated Receptor α Is a Disease-Modifying Therapy for Osteoarthritis
Background/Purpose: Disease-modifying therapeutic agents to prevent progression of Osteoarthritis (OA) are an urgent clinical need. Targeting senescence and autophagy in chondrocytes with small molecules is…Abstract Number: 0880 • ACR Convergence 2023
CD14 Inhibition as a Potential Therapeutic in Post Traumatic OA
Background/Purpose: Osteoarthritis (OA) is the most common joint disorder, and growing evidence has identified inflammation to be a major driver of disease progression. During disease,…Abstract Number: 1591 • ACR Convergence 2023
Complement Factor D/Adipsin Knockout Mice Demonstrate Disparate Pain and Structural Damage Phenotypes in Obesity-induced Post Traumatic Osteoarthritis
Background/Purpose: Osteoarthritis (OA) is the leading cause of musculoskeletal pain, which is a primary driver of care-seeking behavior. There is lack of mechanistic information detailing…Abstract Number: 1730 • ACR Convergence 2023
Gut Microbiota Dysbiosis Impact Autonomic Function in Rheumatoid Arthritis Patients
Background/Purpose: Rheumatoid arthritis (RA) is associated with a high risk of cardiovascular (CV) risks, including accelerated atherosclerosis, left ventricular hypertrophy and decreased heart rate variability…Abstract Number: 1776 • ACR Convergence 2023
Macrophage Migration Inhibitory Factor May Help Maintain Tight Junctions in the Gut by Enhancing Occludin Expression
Background/Purpose: Axial Spondyloarthritis (AxSpA) is a chronic inflammatory disease with multifactorial origins, primarily affecting the musculoskeletal system. Gut inflammation is seen in the majority of…
