In the ischemia-affected zone, merged staining patterns revealed only a few PNs around parvalbumin-containing neurons (Figure 4C′′′) or even the absence of such net-enwrapped neurons (Figures 5C′′′, 6C′′′) while on the contrary, the healthy tissue in all models contained numerous WFA-stained PNs around parvalbumin-containing neurons. This evidence concerns the gene PVALB and ischemia.
