Human Placenta Extract (HPH) Suppresses Inflammatory Responses in TNF-α/IFN-γ-Stimulated HaCaT Cells and a DNCB Atopic Dermatitis (AD)-Like Mouse Model.

ABSTRACT: Atopic dermatitis (AD), a chronic inflammatory disease, severely interferes with patient life. Human placenta extract (HPH; also known as human placenta hydrolysate) is a rich source of various bioactive substances and has widely been used to dampen inflammation, improve fatigue, exert anti-aging effects, and promote wound healing. However, information regarding HPH's incorporation in AD therapies is limited. Therefore, this study aimed to evaluate HPH's effective potential in treating AD using tumor necrosis factor (TNF)-α/interferon (IFN)-γ-stimulated human keratinocytes (HaCaT), immunized splenocytes, and a 2,4-dinitrochlorobenzene (DNCB)-induced AD mouse model. In TNF-α /IFN-γ-stimulated HaCaT cells, HPH markedly reduced the production of reactive oxygen species (ROS) and restored the
