Live-Cell Fluorescence Imaging for Virus-Host Interactions.

ABSTRACT

Recent technological advances in microscopy have facilitated novel approaches to investigate host-pathogen interactions. In particular, improvements in both microscope hardware and engineered biosensors have helped to overcome barriers to live-cell imaging with fluorescence microscopy. Live fluorescent microscopy allows for the detection of discrete signaling events and protein localization, improving our ability to assess the effects of pharmacologic agents, microbes, or infection with high temporal resolution. Here we describe a protocol for long-term live-cell fluorescence imaging of virus infected cell lines.
