Cytokines as potential therapeutic targets for inflammatory skin diseases

A network of pro-inflammatory cytokines is a central feature in the pathophysiology of cutaneous inflammatory diseases. Thus, the delineation of precise roles for particular cytokines and the development of cytokine-directed therapeutics have become areas of intense investigation. While anti-TNF therapeutics have proven to be effective for the treatment of psoriasis, clinical investigations have now begun with other cytokine-directed therapies, such as those targeting IFN-g, IL-12p40, and IL-18. In addition to therapeutics that target cytokines directly, strategies that target cytokine signaling pathways are in development too. In this short review, we summarize key findings from a recent workshop on cytokines as potential therapeutic targets for inflammatory skin diseases.
