Abstract

Acne is a chronic inflammatory disease outbreak in the sebaceous glands within the hair follicle. The proliferation of Propionibacterium acnes (P. acnes) causes monocytes to stimulate secretion of inflammatory cytokines. A number of studies proposed the inhibitory effects of P. acnes-mediated inflammation by several natural extracts. However, studies on the effect of Eurya persicifolia Gagnep. (E. persicifolia) extracts on the inflammatory responses by P. acnes have not been explored yet. In this study, we investigated the anti-inflammatory effect of E. persicifolia extract in the inflammatory reactions induced by P. acnes. We found that E. persicifolia extract successfully diminished the expression levels of inflammatory mediators such as IL-$1{\beta}$, IL-6, TNF-${\alpha}$, and iNOS in P. acnes-activated mouse macrophage RAW 264.7 cells. We found that the immunosuppressive effect of E. persicifolia extract in the P. acnes-activated inflammatory signaling is mediated by the regulation of NF-${\kappa}B$ transcriptional activation, which is a key regulator of inflammatory cytokine expression. Our results suggest that E. persicifolia extract held potentials for the treatment of P. acnes by suppressing NF-${\kappa}B$ signaling pathways.

여드름은 일반적인 피부 염증성 질환으로 알려져 있다. 여드름은 모낭 내 피지선에서 나타나는 만성 염증 질환이다. Propionibacterium acnes (P. acnes)의 증식은 대식세포가 염증성 사이토카인을 분비하도록 자극한다. 최근 연구에서 여러 천연 추출물이 P. acnes에 의해 매개되는 염증반응을 감소시키는 것을 확인하였다. 그러나 P. acnes에 의한 염증반응에서 E. persicifolia Gagnep. (E. persicifolia) 추출물의 억제효과에 관한 연구는 수행되지 않았다. 따라서 본 연구에서는 P. acnes에 의해 유도된 염증 반응에서 E. persicifolia 추출물의 항 염증효과를 조사하였다. P. persicifolia 추출물은 마우스 대식세포주인 RAW 264.7에서 P. acnes에 의해 유도된 IL-$1{\beta}$, IL-6, TNF-${\alpha}$ 및 iNOS와 같은 염증 매개체의 발현 수준을 억제하였다. 또한 E. persicifolia 추출물이 염증성 사이토카인 발현의 주요 조절인자인 NF-${\kappa}B$ 전사 활성화를 억제한다는 것을 발견했다. 본 연구 결과는 P. acnes의 치료를 위한 잠재적인 치료물질로서 E. persicifolia 추출물을 제안한다.
