生殖内分泌研究

生殖現象は生命を維持するうえで基軸となる分野であり、内分泌臓器の精緻な相互作用によって制御されています。生殖機能の調節において、性ホルモンや生理活性物質の情報伝達に関わるメカニズムは未だ解明されるべき点が山積しております。

私どもは、生殖内分泌・不妊症分野におきまして、｢子宮内膜症の病態解析｣や｢卵巣顆粒膜細胞や絨毛細胞における増殖因子や炎症性サイトカインの役割｣に関する研究を行っています。

昨今の医師の研究分野離れが危惧されておりますが、地道な研究活動を確実に業績として実らせ、継続的に新知見を世界に向けて発信することは、医学の発展に貢献するものと考えております。

ヒト子宮内膜症病変およびマウス内膜症モデルによる基礎研究

  1. 子宮内膜症の病態形成における炎症性サイトカインの役割
    子宮内膜症患者の腹水に含まれるマクロファージや、子宮内膜症病変から産生される腫瘍壊死因子(TNFα)をはじめとする炎症性サイトカインの産生バランスが内膜症の病態形成に重要であることを報告しました。また、リポポリサッカライドがCOX-2およびプロスタグランジン発現を介した子宮内膜症細胞の接着・増殖を促し、子宮内膜症の腹腔内炎症を促進することを示しました。
  2. 子宮内膜症細胞が有するアポトーシス抵抗性の解明
    子宮内膜症細胞は類腫瘍的性格をもち、アポトーシス抵抗性を有することが知られています。サバイビンをはじめとする抗アポトーシス因子(IAP)が、子宮内膜症の病態形成に重要な役割を有することを明らかにしました。
  3. 新規薬剤による子宮内膜症治療の探索
    副作用の少ない漢方薬や薬用ハーブが、子宮内膜症モデルマウスにおける腫瘍縮小効果をもつことを明らかにしました。現在も、分子標的薬剤、シグナル伝達阻害剤および植物フラボノイドや、選択的エストロゲン受容体調節薬など、子宮内膜症に対する新規薬物治療の可能性を模索しています。
  4. 生殖器官における性ホルモン受容体の機能解析
    米国NIEHS/NIH等の協力により、子宮内膜症におけるエストロゲン受容体の機能解析や、卵胞発育・排卵過程における役割に関して研究しています。

周産期研究

当院は鳥取県の総合周産期母子医療センターであることから、重症な周産期症例を扱っており、一つ一つの症例を詳細に検討することで生じる疑問を研究の基盤としています。日本周産期新生児学会や日本超音波医学会の専門医、臨床遺伝専門医を取得することを目指して臨床研究に取り組んでいます。

  1. 子宮内膜症および子宮腺筋症による産科合併症の発症リスクに関する疫学的研究
  2. 妊娠初期にみつかる甲状腺機能異常による産科合併症リスクに関する前向き研究
  3. 胎児心エコー検査の診断精度と周産期予後に関する研究
