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 56^th International Workshop of the Ernst Schering Research Foundation that focused on "Cytokines as Potential Therapeutic Targets for Inflammatory Skin Diseases".
