Research Abstract

生活習慣病の要因である肥満や高脂血症は、脂質代謝異常に起因する。脂質代謝の基盤として注目されている細胞内脂肪滴は、種々細胞に普遍的に存在し脂質の蓄積と利用を担う構造体である。絶食により一過的に脂肪蓄積が亢進するマウス肝で、脂肪滴局在タンパク質のADRPが顕著に誘導され、そのADRPは通常の脂肪滴や膜画分とは異なる中間比重画分に分布することを見出した。培養肝細胞HuH-7に脂肪酸を添加すると、ADRPが誘導され脂肪滴が生成するが中間比重脂肪滴は生じない。一方、グルカゴン刺激すると中間比重脂肪滴が出現した。この反応はジブチリルcAMPで再現され、Aキナーゼ阻害剤によって抑制されたことから、肝細胞内脂肪滴形成を伴う脂肪蓄積に、グルカゴン刺激によるcAMP依存性の調節機構が存在することが示された。
