Outline of Research at the Start

本研究では、小胞体ストレスによりCRTが小胞体から減少した場合を想定し、①タンパク質の細胞内輸送に焦点を絞り、シンシチウム化も含めた末梢絨毛形成におけるCRTの役割の解明を目指す。また、②細胞表面に局在するCRTおよび③細胞外に分泌されたCRTがシンシチウム化に与える影響を明らかにすると共に、④臨床検体を用いた解析を行いCRTの病態への関与を検証する。

Outline of Final Research Achievements

Preeclampsia (PE), a pregnancy-specific syndrome, is the major cause of maternal mortality worldwide. Endoplasmic reticulum (ER) stress has been implicated in the pathogenesis of preeclampsia due to being a risk factor of poor placentation. The ER-resident chaperone calreticulin (CRT) is reportedly essential in placentation. Here, we investigated the effects of ER stress on CRT subcellular localization in placental cells. We found that CRT was upregulated in PE sera compared to those in sera of normal pregnancies. In our cell-based assays with the cytotrophoblast model BeWo cells, ER stress induced extracellular release of CRT and extracellular CRT inhibited syncytialization of BeWo cells by impairing the membrane localization of E-cadherin which is critical for syncytialization. Taken together, it was suggested that ER stress-induced extracellular release of CRT may contribute to placental dysfunction by interfering with the differentiation of cytotrophoblasts to syncytiotrophoblasts.

Academic Significance and Societal Importance of the Research Achievements

PEは母児の予後に大きな影響を与える重篤な妊娠合併症であり、確実に治療するには妊娠を終了するしかない。本研究は胎盤形成不全を主病因とする妊娠合併症の新たな治療標的を示唆するものであり、PEの治療戦略の開発に寄与すると考えられる。また、本来小胞体で機能するCRTが細胞外に放出されること、細胞外に放出されたCRTが糖修飾を受けるE-カドヘリンの膜局在化に影響したことから、CRTの小胞体外における新しい機能の解明にも成功した。本研究成果によりタンパク質品質管理の異常と胎盤形成不全という異なる分野の相互理解が深まることが期待される。
