In vivo two-photon imaging of microglia (red) interacting with dendrites (green) and blood vessels (blue) in the somatosensory cortex in a thy1-YFP:cx3cr1^GFP/+mouse. Fluorescent dextran was injected intravenously to label the vasculature. 3D projection image is shown. For more information see the symposium article by Akassoglou et al. (pages 10808–10816).
