FIGURE 2.
Ribosomes are associated with all four FXG types. Confocal micrographs of co-immunostaining for FXR2P to identify FXGs (green) and Y10b antibody to identify 5S and 5.8S rRNA (red) in different brain regions. Ribosome-associated FXGs (arrows) include: (a) Type I FXGs in frontal cortex; (b) Type II FXGs in hippocampal mossy fibers; (c) Type III FXGs in the reticular formation within the medulla; and (d) Type IV FXGs in the deep cerebellar molecular layer.
