Abstract
Alzheimer's disease and other neurodegenerative disorders share some common features at the cellular level, which are often associated with a change in cytoskeletal dynamics. Live cell imaging has been applied to study various aspects of cell physiology including cytoskeletal dynamics. Recently, fluorescence photoactivation (FPA) has been developed as a novel approach to analyze protein dynamics in living cells with high sensitivity. Here, we describe the application of FPA to determine interactions and mobility of the microtubule-associated protein tau in neurons as an example for a disease-related cytoskeletal protein and discuss further applications of FPA to study cytoskeletal dynamics in neurodegenerative diseases.
Keywords: Alzheimer's disease; microtubule-associated protein; neurodegeneration; photoactivatable GFP; photoactivation; tau protein
