초록

염증은 인체에서 가장 흔히 나타나는 증상으로 조직이 손상되면 염증 반응이 발생하고 염증 부위에서 혈관 확장과 혈류가 증가하여 부종이 생긴다. Lipopolysaccharide (LPS)는 Toll-like receptor 4에 의해 인식되고 염증 반응을 일으킨다. 열로 사멸시킨 Enterococcus faecalis 사균체(EF-2001)는 면역 조절 및 예방 활동을 하는 것으로 사전 보고되었고, 항 종양 효과가 있다고 보고되었지만 염증에 미치는 영향에 대해서는 지금까지 연구되지 않았다. 본 연구에서는 LPS에 의한 대식세포 염증 반응에 대한 EF-2001의 효과에 대해 연구하였다. 연구결과에서 EF-2001은 LPS에 의해 유도된 산화 질소의 생성을 감소시켰다. 우리는 EF-2001의 세포 독성이 있는지 확인했으며, 산화 질소의 감소는 세포독성에 의한 것이 아님을 확인하였다. 또한 이러한 EF-2001의 항염증 효과에 대한 분자기전을 연구하였다. LPS에 의한 유도된 iNOS와 COX-2의 발현은 EF-2001에 의해 감소되었다. 더해진 분자기작 분석에서 EF-2001은 LPS로 유도된 ERK, JNK 및 p38 인산화를 농도 의존적으로 억제하였다. 더해진 실험에서 EF-2001은 Akt 인산화를 억제하고 $NF-{\kappa}B$ 억제제인 $I{\kappa}B$ 단백질 발현을 증가시켰다. 또한, EF-2001은 p65의 핵으로의 이동을 억제함을 알수 있었다. 따라서, 이러한 결과는 EF-2001이 항염증 효과를 가지며 염증 질환 치료에 유용 할 수 활용될 수 있음을 시사한다.

Inflammation is the most common condition in the human body. Tissue damage triggers inflammation, together with vasodilation and increased blood flow at the inflamed site, resulting in edema. Inflammatory responses are also triggered by lipopolysaccharide (LPS), a Toll-like receptor Enterococcus faecalis, a gram-positive organism, has been reported to possess immunomodulatory and preventive activities; however, its use may present risks of sepsis and other systemic infections. Heat-killed Enterococcus faecalis (EF-2001) has been reported to induce antitumor activity, but its effects on inflammation are not known. In the present study, we investigated the effect of EF-2001 on LPS-induced macrophage inflammatory responses. EF-2001 treatment reduced nitric oxide (NO) production, indicating suppression of inflammatory reactions. EF-2001 showed no cytotoxicity in macrophages. Further investigation of the anti-inflammatory mechanism of EF-2001 indicated that EF-2001 reduced the LPS-induced expression of inducible nitric oxide synthase and cyclooxygenase-2. EF-2001 also reduced f the LPS induction of several inflammatory molecules involved in the nuclear factor-${\kappa}B$ ($NF-{\kappa}B$) and mitogen-activated protein kinase pathways, including ERK, JNK, and p38 phosphorylation, in a concentration-dependent manner. Additionally, EF-2001 inhibited Akt phosphorylation and increased the expression of the inhibitory ${\kappa}B$ ($I{\kappa}B$) protein, an inhibitor of $NF-{\kappa}B$. EF-2001 also inhibited the nuclear translocation of p65. These results suggest that EF-2001 has anti-inflammatory properties and may be useful for treating inflammatory diseases.
