정상적인 지방세포의 기능이상을 일으키는 주요인자는 무엇인가? | 정상적인 지방세포의 기능이상을 일으키는 주요인자는 아디포카인이라고 명명되는 TNF-α, MCP-1, 그리고 IL-6와 같은 염증성 사이토카인으로, 비만 상태에서 장기적으로 낮은 수준의 만성적인 염증반응을 일으키고, 고인슐린혈증, 제2형 당뇨병과 심혈관 질환 등의 동반질환들의 발생에 기여하는 인슐린 저항성을 유도한다고 알려져 있다2,3). | |
3T3-L1의 세포막에 존재하는 것은? | 3T3-L1은 대표적인 지방세포주로서 지방세포 분화연구에 많이 사용되어 왔다. 또한 세포막에 인슐린 수용체와 glucose transporter 4(GLUT4)가 존재하기 때문에 인슐린과 당대사와 관련된 반응에 민감하게 반응한다. 인체대사와 관련하여 insulin signaling, adipokine분비, GLUT4 translocation, lipogenesis와 lipolysis에 대한 연구에 광범위하게 사용되는 세포모델이다12-14). | |
비만이 초래하는 문제점은? | 비만은 지방세포의 수의 증가뿐만 아니라 지방세포 내 지방구의 축적으로 인한 지방세포 크기의 증가가 일어나고 지방세포의 정상적인 기능이상을 초래한다. 지방세포는 여분의 에너지를 저장하는 역할 이외에 leptin, adiponectin 등을 비롯한 지방세포 유래 호르몬과 아디포카인을 생산하여 내분비기관으로서의 역할을 통해 에너지항상성과 면역기능 등에 관여하는 것으로 알려져 있다1) . |
