Outline of Research at the Start

本研究は、血管石灰化部位に存在する骨細胞様細胞に着目し、血管石灰化形成・進展における骨細胞様細胞の役割の解明を行なう。骨細胞様細胞の機能調節因子の候補であるアンジオテンシンII及び炎症性サイトカインが血管石灰化形成・進展に及ぼす影響を血管石灰化モデルマウスを用いて解析する。加えて、骨細胞様細胞の機能調節による血管石灰化の進展抑制、更には石灰化の退縮を目指す治療法の探索を行なう。

Outline of Final Research Achievements

Aortic culture experiments were performed to evaluate the effects of inflammatory cytokines on vascular calcification. Aortas were excised from mice and cultured in calcification-inducing medium; IL-1β, IL-6, and IL-17A were added, and their effects on calcification were evaluated by micro-CT and tissue staining. The results showed that IL-17A promoted calcification of the aorta in a concentration-dependent manner; IL-1β and IL-6 also showed some promotion tendency, but the difference was not statistically significant.
The results of this study may explain the mechanism of increased risk of vascular complications in patients with psoriasis and psoriatic arthritis. In addition, this model is a relatively simple model for inducing vascular calcification, and we believe it can be applied to the evaluation of candidate drugs for treatment.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、IL-17Aが血管石灰化の促進に働くことを示している。乾癬および乾癬性関節炎は、その病態にIL-17Aが強く関与することが知られている。本研究成果は、乾癬及び乾癬性関節炎患者において血管合併症リスクが増えることの機序の説明になると考える。また、本モデルは比較的簡便に血管石灰化を誘導できるモデルであり、本モデルを用いて治療候補薬剤の評価などにも用いることが出来ると考える。
