Welcome to the Zhu lab. We study single molecular adhesion with force spectroscopy for various cells and disease models. We pioneered in the discovery of force-prolonged bond lifetime, or the "catch bond," using the biomembrane force probe paired with mutation studies and molecular dynamics simulations.
T cells are an important subset of the immune system that plays a pivotal role in regulating various diseases. T cells functions are influenced both by biochemical and biophysical properties at local microenvironment that influences receptor-ligand interactions. Our goal is to understand how these interactions mediated by mechanical properties translate into intracellular signaling, thereby affecting cellular function and fate.
Platelets are key players in both hemostasis and thrombosis. Mechanical stimuli are important in the circulation system. We strive to understand platelet activation, mechanotransduction, and hyperreactivity by characterizing surface receptor-ligand binding kinetics and intracellular signaling using tools such as the biomembrane force probe, biosensors, and mutation studies.
