Triple transgenic CFP/eYFP/eGFP fluorescent reporter mouse to study neuroinflammatory events in vivo by two-photon microscopy.
A: Following injection of 655-Qdots probes, a standard 2-color imaging highlights blood vessels (red) and Thy1-expressing axons (cyan) in the spinal cord of an adult mouse 17 days after EAE induction.
B: In an additional EYFP channel acquired concomitantly, the high density of CD11c-EYFP+ microglial cells (yellow) reveals the pathological activation of CNS resident immune cells during EAE progression
C: At this stage of the disease, circulating LysM-EGFP+ peripheral immune cells (green) are also recruited in the parenchyma, as visible in a 4th color channel.
C-D: Simultaneity of channels acquisition combined with spatial and temporal resolution allows for intravital identification of cellular contact between resident (yellow) and peripheral (green) immune cells (white arrow). These contacts are transients, lasting a few seconds (delay between C and D: 65 sec). Image acquired at 940nm light excitation. Scale bar: 20 μm.
