Description
体重約2 kgのNZW系雄性ウサギを用い、血管炎症モデル(Aguilera CM, 2002)を作成した。すなわち、病変惹起食を8週間給餌して血管炎症モデルとし、ジアシルグリセロール(DAG)投与群(n=10)およびトリアシルグリセロール(TAG)投与群(n=10)に群分けした。試験脂肪(ジアシルグリセロールあるいは同脂肪酸組成のトリアシルグリセロール)は、シリンジを用いて、5週間連日5gを経口投与した。投与期間終了後、血管組織よりRNAを抽出し、炎症関連分子として、vascular cell adhesion molecule (VCAM)-1、macrophage antigen (Mac)-1各遺伝子の発現量を測定した。発現量の測定は、定量的RT-PCR法により行った。また、各遺伝子の発現量は36B4発現量を用いて補正し、未処置(健常)群の値を100%として算出した。
各群の炎症関連分子のmRNA発現強度を図1および図2に示す。ジアシルグリセロール投与群ではトリアシルグリセロール投与群に比較して、Mac-1およびVCAM-1発現量が低値を示した。Mac-1はマクロファージの表面抗原であることから、マクロファージ浸潤に伴う炎症が、ジアシルグリセロール投与群において軽度であったと考えられる。VCAM-1は、活性化された血管内皮においてその発現が増加することから、本分子の発現上昇は血管系炎症の第1段階と考えられている。したがってジアシルグリセロールは、病変局所における炎症を軽減する効果を有すると考えられる。
