Impact of chlorogenic acid on modulation of significant genes in dermal fibroblasts and epidermal keratinocytes

초록

Chlorogenic acid is one of the most abundant polyphenols found in human diet. It is well-documented that chlorogenic acid has a significant impact on human cells, especially in the regulation of inflammation and metabolic processes. However, its role in regulating skin functions, especially with respect to the dermal collagen network or epidermal skin barrier, has not yet been elucidated. Here, we report that chlorogenic acid treatment can induce production of procollagen type I in human dermal fibroblast, Hs68 cell lines. Moreover, this treatment can stimulate upregulation of skin barrier genes, including the ones encoding filaggrin (FLG), involucrin (IVL), and envoplakin (EVPL), in epidermal keratinocytes. Chlorogenic acid also triggered a multifaceted response in the cytokine profile of keratinocytes. Therefore, we suggest that chlorogenic acid can be used to restore the impaired dermal matrix network as well as the epidermal skin barrier. (c) 2021 Elsevier Inc. All rights reserved.
