• 首次证实了在序列和结构上高度复杂的Piezo蛋白是在哺乳动物中鉴定发现的首类机械门控阳离子通道的孔道蛋白,从而确立了机械门控Piezo通道这一全新离子通道家族类型[Nature(Article)2012; Nature(Article)2015; Neuron 2016],开辟了神经科学、生理学、药理学、细胞生物学以及离子通道等研究领域新的研究方向。
• 深入揭示了Piezo通道将机械力刺激高效转化为电化学信号的独特结构基础和精巧工作机制,并鉴定发现了其小分子药物、相互作用蛋白以及剪切变体调控机制[Nature (Article)2018; Nature(Article)2019; Neuron 2020; Nature Communications 2017; Nature Communications 2018]。课题组创新性的开展了先结构后功能的离子通道研究范式,与合作者在国际上首次解析并报导了鼠源Piezo1、Piezo2以及由其课题组所鉴定发现的Piezo1剪切变体Piezo1.1的冷冻电镜三维结构,揭示了其包含共计114次跨膜螺旋区的三聚体螺旋桨状结构,进而结合电生理等功能研究手段揭示了其离子通透与门控机制,并系统性提出了Piezo通道进行机械门控的功能区模块化作用机制假说、杠杆作用机制假说、双门控作用机制假说、以及门塞和闩锁作用机制假说,有力推动了对Piezo通道这类全新复杂离子通道家族的理解。
• 利用多种遗传修饰小鼠模型和相关病人样品,探究了Piezo通道在触痛觉感知、骨的生成与重塑、心脏功能与稳态维持方面的关键生理病理功能,为相关疾病的治疗提供了新的靶点机制(eLife 2019; Cell reports 2019; Nature Communications 2021)。
• 于2012年报导证实Piezo通道的研究成果(Nature 2012),以及于2018年发表报导Piezo1的高分辨率结构与门控机制的研究成果[Nature (Article)2018]被收录进神经生物学教科书(Principles of Neural Science 6
• 发现了STIM1蛋白作为一类新型的温度受体参与暖温区间的温度感知,揭示了哺乳动物精准感知温热变化的分子细胞学机制,提出了哺乳动物利用外周最适温度[optimal preference temperature (OPT) ]作为参比温度(reference temperature)来进行精细温热感知的新假说(Cell Research 2019; Nature chemical Biology 2011)。
