PBM improves neuronal damage and inhibits astrocyte activation in AD mice. A Immunofluorescence double staining of mouse brains using anti-Aβ antibody (red) and anti-GFAP antibody (green) (scale bars 500 μm, 100 μm, and 20 μm, respectively). B Mean fluorescence intensity of Aβ and GFAP. C Nissl and HE staining plots of the hippocampal CA3 region in mice (scale bars 100 μm and 20 μm, respectively). Experimental data are presented as the mean ± standard deviation. Compared with the CON group, **p < 0.01, ***p < 0.001; Compared with the AD group, #p < 0.05, ##p < 0.01
