學習工作經歷
1997-2019年,美國國家癌症研究所,分別擔任Tenure-track研究員,終身資深研究員和幹細胞調控與動物衰老實驗室主任。
2020年起任復旦大學特聘教授。
研究方向
幹細胞,脂代謝與免疫應答在發育、腫瘤和神經退行性疾病中的相互作用:
幹細胞是正常生物發育和衰老的中心細胞,是再生醫學的關鍵資源。腫瘤乾細(CSCs)存在於大多數腫瘤中,是導致腫瘤轉移,疾病復發以及患者最終死亡的禍根。我們對幹細胞的維持,質量調控和與外部環境間的信號傳遞所知甚少。在不久前發表於Nature上的論文中,我們發現幹細胞(包括癌症幹細胞)具有代謝獨特性,就像冬眠動物,主要依賴於脂質儲備的能量。阻斷COPI/Arf1介導的脂質代謝能選擇性地影響幹細胞,導致脂滴積聚,代謝應激,功能缺陷(蛋白質聚集體)並最終壞死。近期發表於Nature Communications的論文中,我們在荷瘤小鼠中確定了詳細的分子機制,阻斷Arf1通路可以起到一石二鳥的效果:不僅能殺死CSCs,還會釋放危險信號而改變腫瘤微環境並引發腫瘤特異性免疫反應,將死亡的CSCs轉化為治療性疫苗以吸引並激活免疫細胞來破壞大塊腫瘤從而達到治療的持久功效。在小鼠大腦中,阻斷Arf1通路能激活小膠質細胞和免疫系統而導致神經退行性疾病。我們的研究系統為探索脂代謝,幹細胞和免疫應答在發育和人類疾病中的相互作用提供了新的機會。我們正在一方面探索該系統的具體分子機制,另一方面又以該系統為基礎來尋找治療癌症和神經退行性疾病的新藥物靶點。
