Caption Immunostaining with microglia markers: Iba-1 (A-L) and mac-2 (M-X) in indicated brain regions of Gba1tm2Karl/Gba1tm2Karl Tg(KRT14-cre)8Brn/? (K14-lnl/lnl) mice (A-F and M-R) and Gba1tm1Karl/Gba1tm1Karl Tg(Nes-cre)1Kln/? (nestin-flox/flox) (G-L and S-X) mice. Iba-1 stains both resting and activated microglia, whereas mac-2 is more selective for activated/proliferating microglia. No mac-2 staining was observed in control mice. Higher magnification of the thalamic region shows the presence of lipid-engorged microglia (arrows) in the Gba1tm2Karl/Gba1tm2Karl Tg(KRT14-cre)8Brn/? mice (E,F,Q and R) but not in Gba1tm1Karl/Gba1tm1Karl Tg(Nes-cre)1Kln/? mice (K,L,W and X). Note the higher activation of microglia in Gba1tm1Karl/Gba1tm1Karl Tg(Nes-cre)1Kln/? mice. All mice were analyzed at end-stage paralysis, corresponding to an age of 2 to 3 weeks. Scale bars: A, 600um; B-E, 80um; F, 20um. Scale within columns is uniform.
