Cytokine and anticytokine therapy in dermatology

Abstract

Cytokines play a pivotal role in the initiation, propagation and regulation of immunologic responses. They are of utmost importance in the pathogenesis of several diseases, including skin diseases. Using cytokines or cytokine antagonists as immunomodulators exhibiting either immunosuppressive or immunostimulatory effects is a rapidly emerging field and is already adding or is about to add significantly to the therapeutic arsenal for malignant and inflammatory dermatoses. Whereas some cytokine therapies, such as IFN-alpha or IL-2, are well-established in melanoma therapy, there are others in early stages of clinical development. The fascinating aspect is the ongoing transition of the work in basic immunobiology of skin diseases into clinical application. Vice versa, observations in clinical trials are also instrumental in further promoting our knowledge of the pathophysiology of skin diseases. In this review, the current status of cytokine and anticytokine therapy for skin diseases is discussed.
