A review of JAK-STAT signalling in the pathogenesis of spondyloarthritis and the role of JAK inhibition

JAK inhibitors are likely to become an important part of the overall treatment paradigm for spondyloarthritis (SpA).Although not fully understood, the pathogenesis of SpA is complex and thought to involve both environmental and genetic factors that together elicit a chronic inflammatory response involving the innate and adaptive immune systems. Several different cytokines, TNF, IL-17A, IL-12/23 and IL-23, which are directly/indirectly affected by JAK molecules, are involved in the pathogenesis o...

JAK/STAT pathway and nociceptive cytokine signalling in rheumatoid arthritis and psoriatic arthritis

Clin Exp Rheumatol. 2021;39(3):668-675.

Crispino N,

Ciccia F.

The JAK/STAT pathway is receiving increasing attention in modulation of nociceptive responses, given its clear role in cytokine signalling. The authors of this review speculate that JAKinibs may have an effect on the modulation of nociception and reduction of pain.Crispino N, et al. review the impact of pain in patients with rheumatic disease and the physiological basis of modulating nociceptive pain. They examine the role of cytokines in the modulation of pain and analyse current clinical JAKin...

JAK selectivity and the implications for clinical inhibition of pharmacodynamic cytokine signalling by filgotinib, upadacitinib, tofacitinib and baricitinib

Ann Rheum Dis. 2021 Mar 19:annrheumdis-2020-219012. Epub ahead of print. DOI: 10.1136/annrheumdis-2020-219012

Meng A,

The first study to combine in vitro inhibition of cytokine responses in whole blood with clinical pharmacokinetics of individual JAKinibs to model daily cytokine-mediated pharmacodynamic profiles in healthy individuals and patients with RA, has demonstrated that JAKinib potencies depended on cytokine stimulus, pSTAT readout and cell type.Traves and colleagues have observed that JAKinibs have unique, differential effects on specific cytokine signalling pathways, dependent on cytokine stimulus, ST...

This analysis provides evidence that immune cell signalling pathways are important in RA. There were consistent differences between RA patients and healthy controls in IFNα, IL-6, IL-10 and GM-CSF+ IL-2 induced JAK/STAT signalling in multiple immune cell subsets.We know that RA is characterised by dysregulation of immune responses, but the exact cause is unknown. Recently, single-cell transcriptomics and mass cytometry confirmed the critical role of activated immune cells and fibroblasts, increa...

Many cytokines associated with RA pathogenesis and pain are affected directly or indirectly by the JAK/STAT pathway, therapeutic targeting may offer promise. Having better understanding of these mechanisms can help clinicians make treatment decisions that optimise the control of inflammation and pain. However, pain in patients with RA is complex and involves multiple driving mechanisms that may differentially occur over time in different people. Although one known constant is that nociceptive ac...
