Abstract:
:Spondyloarthritis is the second most common form of chronic inflammatory arthritis and a unique hallmark of the disease is pathologic new bone formation. Several cytokine pathways have been genetically associated with ankylosing spondylitis (AS), the prototypic subtype of SpA, and additional evidence from human and animal studies support a role of these pathways in the disease. TNF has a key role in SpA as blockade significantly reduces inflammation and destruction, however the treatment does not halt new bone formation. New insights into the TNF pathway were recently obtained from an animal model specifically overexpressing the transmembrane form of TNF. This model leads to axial and peripheral new bone formation which is not seen in soluble TNF overexpression models, indicating different pathogenic roles of soluble and transmembrane TNF in arthritis development. Besides TNF, the IL-23/IL-17 axis is emerging as an important inflammatory pathway in SpA, as a SNP in the IL-23R locus has been associated with developing AS, mice overexpressing IL-23 develop SpA-like features and IL-17 blockade has been shown to be efficacious for AS patients in a phase II trial. In this review, we focus on the cytokine pathways that have recently been genetically associated with SpA, i.e. TNF, IL-1, IL-6 and IL-23/IL-17. We review the current genetic, experimental and human in vivo data available and discuss how these different pathways are involved in the pathophysiology of SpA. Additionally, we discuss how these pathways relate to the pathogenic new bone formation in SpA.
