Abstract:

The skin contains a myriad of immune cells and acts as the first line of defense system against the external environment both as a physical and immune barrier. The cutaneous immune system begins to work even before birth and continuously evolves throughout the lifetime to achieve optimal function by adapting to environmental cues. This study explored the potential mechanism of multi-herb extract CAP against exogenous cutaneous stimulation and discussed the key modulators that drove productive immune responses in skin epidermis and dermal layer immune cells, including keratinocytes, monocytes, and mast cells. Also, a three-dimensional (3D) reconstructed human epidermis model (EpiKutis) was used to perform relevant assays. CAP reduced the expressions of thymic stromal lymphopoietin (TSLP), interleukin-8 (IL-8), prostaglandin E2 (PGE-2), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) that were increased by exogenous stimuli in keratinocytes, 3D EpiKutis, THP-1- derived cells or mast cells. Furthermore, CAP dose-dependently promoted filaggrin level which was decreased by poly (I:C) and LPS induction. These results suggest that CAP might have regulatory functions on keratinocytes, monocytes, and mast cells, which play important roles on the sense, initial and primary stages of the skin inflammatory reactions, respectively.

Key words: multi-herb extract CAP, thymic stromal lymphopoietin, skin inflammatory reactions, keratinocytes, monocytes, mast cells
