Neutrophil extracellular traps (NETs) contribute to the pathogenesis of multiple autoimmune diseases. And research has shown that patients with antiphospholipid syndrome (APS) have higher levels of circulating anti-NET antibodies than healthy controls, indicating a potential biomarker.
PAD2 & PAD4 Modulate Immune Response in TLR-7-Dependent Lupus
A study in mice suggests that targeting peptidyl arginine deiminases in lupus patients may have a therapeutic role in T cell-mediated diseases, affecting innate and adaptive immunity, as well as modulating dysregulated toll-like receptor 7-dependent immune responses…
Neutrophil Extracellular Traps & Their Role in Autoimmunity
Certain medications have been associated for decades with the development of drug-induced autoimmunity. New research published in March 2018 in Arthritis & Rheumatology suggests that NETs (neutrophil extracellular traps) are potentially implicated in the mechanisms that lead to drug-induced autoimmunity.1 Peter Grayson, MD, MSc, head of the Vasculitis Translational Research Program at the National Institute…
Periodontitis May Provide Insight into RA
Researchers explored the role of carbamylated protein (CarP) and neutrophil extracellular traps (NETs) in periodontitis and rheumatoid arthritis (RA). The results showed significantly higher levels of CarP and NETs in patients with both RA and periodontitis than in healthy controls. The data suggest that RA and periodontitis may share an underlying pathogenic mechanism…
Oxidized Mitochondrial DNA May Contribute to Inflammation in SLE
New research examines how the generation of reactive oxygen species and neutrophil extracellular traps may break down the protective mechanisms of mitochondrial DNA, resulting in NETosis in people with autoimmune disease. They found oxidized mitochondrial DNA may contribute to inflammation in such diseases as systemic lupus erythematosus by upregulating type I interferon signatures…
Aggregated Neutrophils Limit Inflammation
A new study suggests understanding this antiinflammatory pathway may lead to new immunomodulatory therapy for resolving inflammation
