李丹博士聚焦蛋白相分离和相变，开发基于冷冻电镜的电子衍射、螺旋纤维成像、in-cell核磁等前沿技术，研究蛋白分相正常生理功能的原子分子基础，及蛋白淀粉样相变导致神经退行性疾病的原子分子基础。

蛋白相分离和相变、神经退行性疾病

方向1: 综合运用多种生物物理、生物化学和细胞生物学手段，研究生理和病理条件下的蛋白质相分离和无膜细胞器的组装与调控。

方向2: 研究神经退行性疾病，如阿尔兹海默症(AD)、帕金森症(PD)、渐冻人症(ALS)等，蛋白异常相变聚集的发生和致病机理。发展运用冷冻电镜电子衍射、螺旋纤维三维重构技术，解析蛋白淀粉样聚集纤维原子结构，阐释聚集体致病的分子机理, 开发相关疾病的治疗药物和临床诊断标记物。
