Genetic evidence links the IL-23-IL-17 pathway to inflammation in these rheumatic diseases, and mechanistic data from mice support a functional role for IL-23-IL-17 pathway activation in the development of enthesitis and in entheseal bone formation.
<b>Background:</b> Ankylosing spondylitis (AS) is a common debilitating rheumatic disease in which the innate immune components especially the Interleukin (IL)-23/IL-17 axis related genes play important role in its pathogenesis.
The ability of VIP to counteract the enhancing effect of proinflammatory molecules on IL-17R and the IL-12 family of cytokines corroborates and amplifies the beneficial effect of this endogenous neuroimmunopeptide in rheumatic diseases.
