Outline of Annual Research Achievements

申請者らの目的は、妊娠高血圧症候群胎盤におけるオートファジー抑制機構を明らかにし、その治療法の開発に繋げることである。これまでに、新規オートファジー誘導因子TFEBが胎盤の形成に重要であることを報告してきた。その中で、これまでは母体側に浸潤する絨毛外栄養膜細胞におけるオートファジー機能に注目してきた。一方、胎盤の本体にあたる合胞体栄養膜細胞における小胞体ストレスがオートファジー抑制に働くことを明らかにし(Nakashima A, Cheng SB, Kusabiraki T, Motomura K, Aoki A, Ushijima A, et al. Endoplasmic reticulum stress disrupts lysosomal homeostasis and induces blockade of autophagic flux in human trophoblasts. Sci Rep 2019; 7: 11466.)、それに関連して、Cheng S, Banerjee S, Nakashima A, Jash S, Sharma S. et al. Novel blood test for early biomarkers of preeclampsia and Alzheimer's disease. Sci Rep. 2021;11:15934.にて、オートファジー抑制をベースとしたPE診断法の提案を行った(オートファジー抑制による異常蛋白検出による)。さらに、本研究期間において、胎盤形成における合胞体栄養膜細胞の分化抑制にもオートファジー抑制が関わることを明らかにした(Furuta A, Shima T, Kawaguchi M Nakashima A, et al. The autophagy-lysosomal machinery enhances cytotropho-blast-syncytiotrophoblast fusion process. in press)。今後は、絨毛外栄養膜細胞および合胞体栄養膜細胞をターゲットとしたオートファジー抑制の復帰メカニズムを明らかにしていく。
