Ankylosing spondylitis: an autoimmune or autoinflammatory disease?

2021

Ankylosing spondylitis (AS) is a chronic inflammatory disease with hallmarks of both autoimmune and autoinflammatory pathology. In this Review, the authors examine the evidence for both disease processes and aim to reconcile the two.Ankylosing spondylitis (AS) is a chronic inflammatory disorder of unknown aetiology. Unlike other systemic autoimmune diseases, in AS, the innate immune system has a dominant role characterized by aberrant activity of innate and innate-like immune cells, including gamma delta T cells, group 3 innate lymphoid cells, neutrophils, mucosal-associated invariant T cells and mast cells, at sites predisposed to the disease. The intestine is involved in disease manifesta…

Inflammasome activation in Ankylosing Spondylitis is associated to gut dysbiosis

2021

Objective: We undertook this study to evaluate the activation and functional relevance of inflammasome pathways in ankylosing spondylitis (AS) patients and rodent models and their relationship to dysbiosis. Methods: An inflammasome pathway was evaluated in the gut and peripheral blood from 40 AS patients using quantitative reverse transcriptase–polymerase chain reaction (qRT-PCR), immunohistochemistry (IHC), flow cytometry, and confocal microscopy, and was compared to that of 20 healthy controls and 10 patients with Crohn’s disease. Bacteria was visualized using silver stain in human samples, and antibiotics were administered to HLA–B27–transgenic rats. The NLRP3 inhibitor MCC950 was admini…

Pro-inflammatory CX3CR1+ CD59+ TL1A+ IL-23+ monocytes are expanded in patients with Ankylosing Spondylitis and modulate ILC3 immune functions

2018

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.

2018

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…
