title: The role of immune tolerance in preventing and treating arthritis.
abstract: It has become increasingly clear that the innate and adaptive arms of the immune response cooperate in generating autoimmune damage in the pathogenesis of rheumatoid arthritis and juvenile idiopathic arthritis. Treatment targets the immunologic pathophysiology of the disease and is based on regaining immune tolerance. Recently introduced biological agents neutralize or simply block cytokines and their proinflammatory pathways, with favorable clinical outcome. However, major downsides are their lack of specificity and the need of continuous administration to be effective. Possibly, more can be gained from a specific approach. Indeed, recent findings suggest that targeting antigen-specific T cells can reinstate regulatory mechanisms and thus induce immune tolerization. This improved understanding has paved the way to novel immunotherapeutic approaches, some of which will be discussed here.
