Mechanobiology: a new model of integrin activation by membrane tension

点击翻译按钮获取中文摘要

This project aims to address a fundamental question in mechanobiology on how integrin receptor coordinates with force to mediate cell spreading, migration, growth and survival. With an observation that membrane deformation enhances integrin binding, the project expects to establish a new model of integrin activation by membrane tension. It will develop an integrated approach combining single-molecule force probes, super resolution microscopy, microfluidics and molecular dynamics simulations. It is expected that the role of membrane tension in promoting cell adhesion will be defined at molecular scale, and the link between integrin activation and Piezo calcium channel mediated membrane tension sensing will be delineated.
