   深圳湾实验室张洋研究员于2022年8月4日应邀来深圳先进技术研究院进行学术交流,并作题为:“TMEM16F phospholipid scramblase mediates cell-cell fusion”的学术报告。Cell fusion is fundamental to the reproduction, development, and homeostasis of multicellular organisms. In addition to various cell type-specific fusogenic proteins, cell surface externalization of phosphatidylserine (PS), a universal eat-me signal in apoptotic cells, has been observed in different cell fusion events. Nevertheless, the molecular underpinnings of PS externalization and cellular mechanisms of PS-facilitated cell-cell fusion are unclear. Our lab report that TMEM16F, a Ca2+-activated phospholipid scramblase (CaPLSase), plays an essential role in placental trophoblast fusion by translocating PS to cell surface independent of apoptosis. We also identify one of the physiological activation mechanisms of TMEM16F in human trophoblast fusion. Our findings provide insight into understanding cell fusion mechanism of other cell types and demonstrate one approach to understand TMEM16F’s biological functions in wide-ranging physiological and pathological processes, including blood coagulation, bone mineralization, HIV infection, trophoblast fusion, and SARS-CoV2-mediated syncytialization.
