Gene expression of cytokines in atopic eczema before and after ultraviolet A1 phototherapy

Abstract

We have shown that the resolution of extrinsic AE lesions following phototherapy is accompanied by significant reduction of mRNA expression of IL-5, IL-13 and IL-31, supporting current concepts that these cytokines play a crucial role in the pathogenesis of extrinsic AE and possibly represent targets for phototherapy.
