Neutrophils, often hailed as guardians against infections, are maligned when it comes to rheumatoid arthritis (RA) due to their role in both the initial stage and disease progression. A new multicenter work, “A Neutrophil Activation Biomarker Panel in Prognosis and Monitoring of Patients with Rheumatoid Arthritis,” seeks to expand the literature on this topic.1 The…
IgG from Patients with Autoimmune Disease Activates Neutrophils
A recent study examined the effects of immunoglobulin G (IgG) on isolated neutrophils of patients with autoimmune disease. Researchers found different autoimmune diseases have distinct patterns of IgG-mediated integrin activation and neutrophil function, which may explain disease-specific differences in vascular damage and dysfunction…
MicroRNA Mediates Gene Regulation That Underlies JIA Pathology
Through the use of large-scale transcriptome analysis, researchers have gained insight into the role of innate immunity in juvenile idiopathic arthritis (JIA) pathology. Specifically, transcriptomes of neutrophils in chronic inflammatory states demonstrate extensive network rewiring caused by microRNA, suggesting a role for alternative splicing in JIA pathogenesis…
Rheumatology Researchers Explore Role of Neutrophils in Autoimmunity
SAN FRANCISCO—To unravel the mysteries of how autoimmunity begins in the body and, one day, to interrupt that process, rheumatology researchers are exploring the role of neutrophils, especially when they form and release neutrophil extracellular traps (NETs). At a panel discussion on Nov. 6, 2015, held at the American College of Rheumatology’s Basic Research Conference,…
Complement Polymorphism Plays Role in RA Pathology
Study proposes increased active C5a recruits neutrophils to arthritic joints to maintain inflammation
Controlled Neutrophil Production Could Improve Immunometabolism
A new study of cellular biology in mice unexpectedly turned up a potential pathway to help patients with rheumatoid arthritis (RA).
Aggregated Neutrophils Limit Inflammation
A new study suggests understanding this antiinflammatory pathway may lead to new immunomodulatory therapy for resolving inflammation
