  • 力学生物学(Mechanobiology)是一门融合生物学、物理学、医学、工程学与材料科学的新兴前沿交叉学科。近年来的研究表明,细胞黏附、迁移与分化,组织生长、修复与维持,胚胎发育,肿瘤生长与转移,免疫激活等一系列关键生理病理过程,均受到力学信号的调控。力学生物学旨在阐明力学信号在分子、亚细胞、细胞、组织、器官等不同层次对生命体行为进行调控的机制,并基于这些机制理解推动相关生物医学应用。


    力学生物学的物质基础是一系列力敏感生物大分子及其通过动态相互作用形成的超分子复合物。这些力敏感分子与复合物通常动态富集于细胞的关键连接部位,如细胞间连接(包括胞间连接与紧密连接等)、细胞与胞外基质间的连接(如黏附连接等)、细胞骨架内部及骨架之间的连接,以及细胞骨架与细胞核等细胞器之间的连接。这些力敏感大分子及其复合物在特定时空的构象变化与相互作用的力学—化学耦合动态,构成了生命体在亚细胞、细胞、组织与器官等层次的力学功能涌现的分子基础


    本课题组聚焦生命医学问题,以“生物大分子构象与相互作用的力学—化学耦合动态调控机制”为核心研究方向,积极探索其在生物医学中的潜在应用。研究注重物理与生物、医学的交叉融合,综合运用动态单分子与单细胞力学操控及成像技术,并结合分子动力学模拟高分子物理建模等手段,从而在实验与理论上协同理解生物大分子构象与相互作用的力学—化学耦合动态调控,进而逐步揭示在生理与病理过程中发挥关键作用的蛋白质、核酸等生物大分子功能实现的物理机制。
