From: RIG-I contributes to the innate immune response after cerebral ischemia
MCAO increases RIG-I immunoreactivity in astrocytes. Confocal images corresponding to the hippocampus of sham animals (top) and animals that were sacrificed 4 h after MCAO (bottom). Image is taken from the side of the brain ipsilateral to MCAO. Sections were stained for RIG-I (red) and GFAP (green). Arrows point to RIG-I positive astrocytes. Scale bar = 20 μm
