면역체계에서 대식세포는 어떠한 역할을 하는가? | 면역 반응의 일종인 염증반응은 미생물이나 화합물 등에 의해 유해한 자극이 가해진 후의 인체의 방어기전으로, 자극의 제거 및 손상된 조직의 수복과정까지의 모든 과정을 가리킨다[3]. 면역체계에서 대식세포(macrophage)는 염증반응과 면역기능을 조절하며, 항상성을 유지하는데 있어 중요한 역할을 한다. Lipopolysaccharide (LPS)의 자극에 의해 활성이 증가하며, 이 LPS는 외부의 항원과 공유결합으로 결합된 지질과 다당류의 복합체로서 주로 그람음성균(Gram-negative bacteria)의 외막 성분으로 존재하는 내독소(endotoxin)이다[4, 5]. | |
염증반응이란 무엇인가? | 면역 반응의 일종인 염증반응은 미생물이나 화합물 등에 의해 유해한 자극이 가해진 후의 인체의 방어기전으로, 자극의 제거 및 손상된 조직의 수복과정까지의 모든 과정을 가리킨다[3]. 면역체계에서 대식세포(macrophage)는 염증반응과 면역기능을 조절하며, 항상성을 유지하는데 있어 중요한 역할을 한다. | |
대식세포는 어떤 내독소의 자극에 의해 활성이 증가될 수 있는가? | 면역체계에서 대식세포(macrophage)는 염증반응과 면역기능을 조절하며, 항상성을 유지하는데 있어 중요한 역할을 한다. Lipopolysaccharide (LPS)의 자극에 의해 활성이 증가하며, 이 LPS는 외부의 항원과 공유결합으로 결합된 지질과 다당류의 복합체로서 주로 그람음성균(Gram-negative bacteria)의 외막 성분으로 존재하는 내독소(endotoxin)이다[4, 5]. 손상된 조직에 있는 세포나 단백질들은 사이토카인의 분비를 촉진시키면서 다른 세포들과 작용하여 면역반응이 시작되고 염증상태가 유도된다. |
