비만세포의 역할은? | NFκB는 염증반응에 관여하는 여러 사이토카인의 발현을 조절하는 중요한 전사인자로 알려져 있다7). 비만세포는 피부, 호흡기계 및 소화기계를 포함하는 인체의 광범위한 부위에 분포하며, 다양한 외부자극에 의해 염증유발과 면역조절을 할 수 있는 많은 매개물질을 생산할 수 있으므로 선천 면역과 적응 면역에서 중요한 역할을 한다. 특히 비만세포는 항원으로 유발되는 IgE 매개 알러지 반응에 대한 주요한 작용 세포로 인식되어 왔다8). | |
FE가 비만세포 탈과립과 cytokine의 생산가 유전자의 발현 억제한다고 판단한 연구 결과는? | 이를 종합해 볼 때 FE는 비만세포 탈과립과 cytokine의 생산가 유전자의 발현 억제하는데 이는 세포내 ROS의 생성을 억제하고, MAPK 신호전달경로와 NFκB의 핵내 전이를 저해함으로써 비만세포의 활성을 억제하는 것으로 생각된다. | |
FE가 비만세포의 염증매개물질 분비에 어떤 작용을 하나요? | TNF-α는 주로 비만세포, 대식세포, 호염기구, 호중구, 호산구와 상피세포 등 알러지성 폐의 염증에 반응하여 활성화된 여러 세포에 의해 생산되며, 비만세포와 호염기구에서 항원항체반응의 결과로 합성, 분비되는 강력한 염증매개물질이다21). 본 연구에서 FE는 IL-4과 TNF-α의 생산을 유효하게 억제하였고, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-13, TNF-α와 GM-CSF 같은 다양한 비만세포 유래 사이토카인의 유전자 발현을 억제하였다. |
