간이란? | 간은 간실질세포, 쿠퍼 (Kupffer) 세포 및 간 성상 세포 (hepatic stellate cell)를 포함하는 다양한 세포로 구성되며1), 산화적 스트레스 (oxidative stress)를 억제하여 해독에 관여하는 중요한 기관이다2,3). 산화적 스트레스는 손상 및 세포사멸을 포함한 세포 기능 장애에서 흔히 발생하는 기전으로 손상 및 염증의 유도를 통한 조직손상은 활성산소종 (reactive oxygen species, ROS) 생산과 세포의 항산화 활동 사이의 불균형과 관련되어 있다4,5). | |
과도한 활성산소종 생산이 이루어졌을 때 어떻게 되는가? | 산화적 스트레스는 손상 및 세포사멸을 포함한 세포 기능 장애에서 흔히 발생하는 기전으로 손상 및 염증의 유도를 통한 조직손상은 활성산소종 (reactive oxygen species, ROS) 생산과 세포의 항산화 활동 사이의 불균형과 관련되어 있다4,5). 과도한 ROS 생산은 막유동성 및 단백질 구조 변형을 통해 인지질막을 변형시키며 이를 통해 세포사멸을 유도한다6). 따라서 산화적 스트레스의 과도한 증가는 급만성 간 질환을 포함한 다양한 질환을 야기하는 주요 원인으로 보고되어 왔다7,8). | |
