腹部大動脈瘤は下肢の動脈瘤も含め、動脈の分岐点で乱流の生じやすい部位に好発し、腹部大動脈瘤は多くは大動脈分岐上、総腸骨動脈瘤や総大腿動脈瘤も同様に分岐直上にできる。一方、直線状になっている外腸骨動脈や浅大腿動脈の瘤化はほとんどない。本研究の目的は、大動脈瘤抑制のための血流改変モデルを作製解析することで腹部大動脈瘤形成および進展のメカニズムを明らかにし、その上で新たな血管病の治療戦略を呈示することにある。

The activity of endogenous MCP-1 was significantly lower in the calsitriol group than in the Saline group. However, there was no significant difference in expression level of IL-1βand MMP-9 causing degeneration of the extracellular matrix between the Saline and calsitriol groups. In that series, we decided to evaluate another anti-inflammatory subject that can suppress atherosclerotic disease. Montelukast is a selective CVS-LT-1receptor antagonist that could surpress atherosclerotic diseases. We evaluated the in vitro properties of montelukast and its in vivo activities in an angiotensinⅡ-infused apolipoprotein E-deficient AAA mouse model. Relative to control,montelukast significantly suppressed gene expression of MMP-2, MMP-9, and IL-1β.In vivo,montelukast significantly decreased aortic expansion and induced infiltration of M2 macrophages.
