Is There a Role for Inflammasome Activation in PsA Pathogenesis and Its Comorbidities?
Background/Purpose . New data has emerged about the role of the inflammasome in psoriasis and psoriatic arthritis (PsA). The assembly of the inflammasome components in…Abstract Number: 1472 • 2014 ACR/ARHP Annual Meeting
Synovial Fluid from Rheumatoid Arthritis Patients Modulates the Immunophenotype and Viability of Monocytes
Background/Purpose Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by infiltration of the synovium by inflammatory cells that destroys the cartilage and the…Abstract Number: 1196 • 2014 ACR/ARHP Annual Meeting
Inflammation Develops in a Toll-like Receptor 9-Independent Manner in Experimental Arthritis and Rheumatoid Arthritis
Background/Purpose Rheumatoid arthritis (RA) is an inflammatory disease of unknown etiology. Toll-like receptor (TLR) 9 recognizes pathogen-derived DNA and even self DNA under certain circumstances.…Abstract Number: 1199 • 2014 ACR/ARHP Annual Meeting
Alarmins S100A8/S100A9 Aggravate Osteophyte Formation in Experimental Osteoarthritis and Predict Osteophyte Progression in EARLY Human Osteoarthritis in the Dutch Check Cohort
Background/Purpose The main pathological feature of osteoarthritis (OA) is degradation of the articular cartilage. Other important hallmarks include subclinical inflammation of the synovium and ectopic…Abstract Number: 1044 • 2014 ACR/ARHP Annual Meeting
Novel Compound Cytokine Release Inhibitory Drug 3 (CRID3) Inhibits the NLRP3 Inflammasome in Rheumatoid Arthritis
Background/Purpose: The NLRP3 inflammasome is a multi-protein complex activated in response to environmental pathogens. This results in caspase-1-dependant cleavage of pro-IL-1β and IL-18 to their…Abstract Number: 2500 • 2013 ACR/ARHP Annual Meeting
Mast Cells Are a Major Source Of IL-17 In Synovium and Extra-Articular Tissues In Spondyloarthritis Related Diseases
Background/Purpose: IL-17 plays a key role in the pathogenesis of spondyloarthritis (SpA) as demonstrated by a recent proof-of-concept trial with the anti-IL17A mAb secukinumab. The…Abstract Number: 1778 • 2013 ACR/ARHP Annual Meeting
Physical Interactions Between Histidyl-tRNA Synthetase and Endogenous/Exogenous Alarmins Enhance Immunogenicity In a Model Of Antigen-Induced Myositis
Objective: To assess the biological interplay between histidyl-tRNA synthetase (HRS) and different endogenous/exogenous ligands capable of generating signals through MyD88-dependent receptor systems in idiopathic inflammatory…Abstract Number: 1156 • 2013 ACR/ARHP Annual Meeting
Suppression Of Immune Responses and Joint Inflammation By Myeloid-Derived Suppressor Cells In a T Cell-Dependent Mouse Model Of Rheumatoid Arthritis
Background/Purpose: Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of innate immune cells with immunosuppressive properties. We previously identified MDSCs in the synovial fluid (SF)…Abstract Number: 1168 • 2013 ACR/ARHP Annual Meeting
Innate Immune Cell Production Of Interleukin-12 Drives CpG-Induced Macrophage Activation Syndrome
Background/Purpose: Hemophagocytic syndromes are caused by an uncontrolled systemic inflammatory response resulting in cytopenias, multisystem organ failure, and rapid death, often despite aggressive therapy. Macrophage…Abstract Number: 1149 • 2013 ACR/ARHP Annual Meeting
Phenotypic and Molecular Profile Of Innate Lymphoid Cells In Chronic Synovial Inflammation
Background/Purpose: Innate lymphoid cells (ILCs) represent a novel family of effector and regulatory cells in innate immunity and tissue remodelling. The family comprises several phenotypically…
