Confocal microscopy with cell specific markers finds neuronal and microglial expression of NADPH oxidase subunit gp91 phox . Brain sections from ethanol-poly I:C-treated mice were double-labeled for gp91phox in green with neuronal marker MAP-2, microglial marker Iba1, or astroglial marker GFAP in red. Co-labeling was investigated using a Leica SP2 LCS confocal microscope with associated software. The representative images shown are from dentate gyrus of mice treated with ethanol-poly I:C. The left panel of pictures shows gp91phox + IR. The middle panel shows cell specific markers, for example, neuronal MAP-2 (upper panel), microglial Iba1 (middle) and astrocyte GFAP (lower panel) pictures. Merged images are to the right. Merged yellow indicates red and green are combined and likely co-localized within the marked cell. Merged pictures on the right with enlarged cells suggest that gp91phox + IR is expressed in MAP-2 neurons (yellow) and Iba1 microglia (yellow), but not in astrocytes. Scale bar, 30 μm; inset 5 μm.
