title: Signalling, inflammation and arthritis: Crossed signals: the role of interleukin-15 and -18 in autoimmunity.
abstract: Several cytokines are involved in the complex processes ultimately leading to autoimmune diseases. In a preceding review, we have already discussed the role of the IL-12 and -17 families of cytokines. This review is focused on IL-15 and -18. Both these molecules have pro-inflammatory activity and act on many cell types and because of their broad spectrum of activity they play an important role in autoimmunity and disease pathogenesis. Their biological activity is ultimately regulated by the signalling cascades set into motion within their target cells. In this second review, we will, once again, describe the signal transduction pathways activated by these two cytokines and focus on how this relates to the pathogenesis of autoimmune diseases. We will also describe some of the therapeutic approaches that are being investigated to curtail the pro-inflammatory activities of these two molecules.
