Pro-inflammatory CX3CR1+ CD59+ TL1A+ IL-23+ monocytes are expanded in patients with Ankylosing Spondylitis and modulate ILC3 immune functions
Gut derived ILC3 have been demonstrated to participate in AS pathogenesis. CX3CR1+ mononuclear phagocytes (MNP) have been demonstrated to modulate ILC3 function in the gut. The aim of this study was to study the role of pro-inflammatory CX3CR1+ CD59+ MNP in modulating ILC3 function in AS patients.
Macrophage Migration Inhibitory Factor Induces Inflammation and Predicts Spinal Progression in Ankylosing Spondylitis
Objectives: To understand the role of macrophage migration inhibitory factor (MIF) in the pathogenesis of Ankylosing Spondylitis (AS). Methods: AS patients satisfying the modified New York criteria were recruited for the study. Healthy volunteers, rheumatoid arthritis and osteoarthritis patients were included as controls. Based on the annual rate of increase in mSASSS scores, AS patients were classified as progressors or non-progressors. MIF levels were quantitated by ELISA in the serum and synovial fluid. Predictors of AS progression were studied by logistic regression analysis. Immunohistochemistry of ileal tissue was performed to identify MIF producing cells. Flow cytometry was used to r…
Macrophage Migration Inhibitory Factor Induces Inflammation and Predicts Spinal Progression in Ankylosing Spondylitis
Objective: To investigate the role of macrophage migration inhibitory factor (MIF) in the pathogenesis of ankylosing spondylitis (AS). Methods: Patients who met the modified New York criteria for AS were recruited for the study. Healthy volunteers, rheumatoid arthritis patients, and osteoarthritis patients were included as controls. Based on the annual rate of increase in modified Stoke AS Spine Score (mSASSS), AS patients were classified as progressors or nonprogressors. MIF levels in serum and synovial fluid were quantitated by enzyme-linked immunosorbent assay. Predictors of AS progression were evaluated using logistic regression analysis. Immunohistochemical analysis of ileal tissue was…
Proinflammatory CX3CR1+CD59+Tumor Necrosis Factor–Like Molecule 1A+Interleukin‐23+ Monocytes Are Expanded in Patients With Ankylosing Spondylitis and Modulate Innate Lymphoid Cell 3 Immune Functions
Objective: Gut-derived innate lymphoid cell 3 (ILC3) has been shown to participate in the pathogenesis of ankylosing spondylitis (AS). CX3CR1+ mononuclear phagocytes (MNPs) have been demonstrated to modulate ILC3 function in the gut. This study was undertaken to investigate the role of proinflammatory CX3CR1+CD59+ MNPs in modulating ILC3 function in AS patients. Methods: MNP subsets in the blood of AS patients and controls were analyzed by flow cytometry. The presence of CX3CR1+CD59+ cells in tissue was confirmed by confocal microscopy. Expression of the proinflammatory chemokines CX3CL1 and CCL2 and decoy receptor 6 (DcR-6) was analyzed. Peripheral CX3CR1+CD59+ cells were cocultured with I…
