FIR light treatment ameliorated Aβ deposition in the cortex and hippocampus. A Representative images of Aβ (6E10) staining in the cerebral cortex and hippocampus from WT, APP/PS1 and FIR light-treated APP/PS1 mice. B Percentage of Aβ plaque area in the cerebral cortex (n = 4). C Aβ plaque density in the cerebral cortex (n = 4). D Percentage of Aβ plaque area in the hippocampus (n = 4). E Aβ plaque density in the hippocampus (n = 4). F The levels of Aβ1-40 and Aβ1-42 in the PBS fractions from the cerebral cortex (n = 5). G The levels of Aβ1-40 and Aβ1-42 in the guanidine hydrochloride fractions from the cerebral cortex (n = 5). Data were means ± SEM, *p < 0.05, **p < 0.01. ND: not detected
