(J-M) DOX also normalized CA1 levels of GFAP immunoreactivity (IR) in hTau-A152T(L1) mice, as shown by representative photomicrographs (J-L) and quantitation of GFAP immunoreactivity (M). Scale bars: 300 µm (A-I), 25 µm (J-L). n = 3-4 mice per genotype. *P < 0.05 by two-tailed Welch's t test without Holm adjustment. Values are means ± SEM. a.u., arbitrary units.
