Rheumatoid arthritis (RA) patients have variable but comparable NLRP3-inflammasome induction to controls

Skin inflammatory reactions to capsaicin in rheumatoid arthritis patients compared to healthy controls

Objective: Previous studies have examined the role of sensory nerves and neural mediators in symmetrical joint inflammation and autoimmunity in rheumatoid arthritis (RA). In this study, we sought to examine the association between capsaicin skin test and disease activity in RA patients. Materials and Methods: Eighty RA patients (case group) and 20 healthy volunteers were enrolled in this experi...

Enhanced activity of NLRP3 inflammasome in peripheral blood cells of patients with active rheumatoid arthritis

INTRODUCTION Interleukin-1β (IL-1β) is a major inflammatory cytokine, produced predominantly by innate immune cells through NLRP3-inflammasome activation. Both intrinsic and extrinsic danger signals may activate NLRP3. Genetic variations in NLRP3-inflammasome components have been reported to influence rheumatoid arthritis (RA) susceptibility and severity. We sought to assess the activity of NLR...

Patients with Active Rheumatoid Arthritis Have Lower Frequency of nTregs in Peripheral Blood

Background: Patients with rheumatoid arthritis (RA) suffer from wide ranges of autoimmune reactions in joints. The mechanism of which is generally unknown and maybe associated with Treg deregulation. Objective: To compare the frequency of nTregs in peripheral blood of patients with active rheumatoid disease with healthy individuals. Methods: Twenty five newly diagnosed patients with active RA d...

Anti-TNF Treatment Response in Rheumatoid Arthritis Patients Is Associated with Genetic Variation in the NLRP3-Inflammasome

OBJECTIVE Many patients with rheumatoid arthritis (RA) benefit from tumor necrosis factor-α blocking treatment (anti-TNF), but about one third do not respond. The objective of this study was to replicate and extend previously found associations between anti-TNF treatment response and genetic variation in the TNF-, NF-κB- and pattern recognition receptor signalling pathways. METHODS Forty-one ...
