Cytokines and cytokine receptors remain an area of great interest for the development of targeted therapies for cutaneous inflammatory diseases. Anti- TNF therapeutics have proven to be effective in the treatment of psoriasis, and clinical investigations have now begun for 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. This book summarizes the findings of the 56th International Workshop of the Ernst Schering Research Foundation that focused on "Cytokines as Potential Therapeutic Targets for Inflammatory Skin Diseases".
