我们实验室的研究分为两部分:
一、免疫和神经生物学领域的重要生物大分子(可溶/膜蛋白和核酸)的结构和功能的关系。细胞表面受体犹如天线一样感知胞外信号并对之做出反应。我们对参与重要细胞信号转导的膜上受体/配体复合物结构与其功能的关系进行研究。我们的研究将用来回答以下问题:配体是怎样被细胞表面的相应受体(如GPCRs)识别的?他们相互识别的专一性/选择性是如何实现的?结合配体后,受体的构象发生了怎样的改变?受体构象的变化是如何激活或抑制胞内信号途径的?*蛋白又是如何*受体的功能的?另外我们还研究参与免疫和神经信号转导的重要胞内蛋白(复合物)分子的结构和功能的关系。 二、天然免疫系统激活的新基因及其信号通路的研究;免疫细胞(如巨噬细胞)分化、活性调节的信号分子及其信号转导机制,炎症体激活。
除了上述结构生物学及信号通路方面的基础研究外,我们也对在免疫及神经退行性疾病中起关键作用的可溶/膜蛋白(复合物)的结构进行解析,并利用这些结构信息理性设计小分子药物治疗上述疾病。研究成果发表在 Cell Host & Microbe (IF=13.728),Nature Structural & Molecular Biology (IF=13.685)等杂志上。
