Abstract

Atopic dermatitis (AD) is a chronic inflammatory skin disease that is not fully understood. Defects in skin barrier function and dysregulation of the Th2 immune response are thought to be pivotal in AD pathogenesis. In this study, we used keratinocytes and AD-like skin equivalent models using Th2 cytokines IL-4 and IL-13. The keratinocytes and AD-like skin model were used to investigate the effect of dipotassium glycyrrhizinate (KG), which is widely used as an anti-inflammatory agent for AD treatment. KG decreased AD-related gene expression in keratinocytes stimulated with Th2 cytokines. KG alleviated AD-like phenotypes and gene expression patterns and inhibited release of AD-related cytokines in the AD-like skin equivalent models. These findings indicate KG has potential effectiveness in AD treatment and AD-like skin equivalent models may be useful for understanding AD pathogenesis.
