Abstract
Microglia are morphologically dynamic cells, neatly arranged in an interconnected three-dimensional lattice throughout the brain, constantly surveying the parenchyma, and swiftly responding to a variety of external stimuli. Capturing the dynamics of their morphology, reaction to trauma, pathogens, or endogenous stimuli, and studying changes in their network in their physiological environment requires the use of two-photon microscopy, as well as a precise repositioning strategy. Herein, we describe a robust repeatable localization method, coupled with optimized in vivo two-photon microscopy for long-term imaging of single microglia cells in the mouse brain.
