GFAP and frontotemporal dementia: We also analysed the glial response in the hippocampus of FTD mice using first the astroglial marker GFAP (Fig. 8A–D), which resulted to be elevated in the CA1 subfield, but only at PND90 (genotype: F(1,29) = 4.201, p < 0.05; interaction: F(1,29) = 5.915, p < 0.05; Fig. 8B).
