Partial CX3CR1 deficiency affects Aβ levels but does not affect total microglial numbers or the numbers of plaque-associated microglia. Quantification of (A) Aβ (1-42) and (B) Aβ (1-40) by ELISA in brain homogenates of 10-month old mice (Numbers represent mean ng of Aβ/mg brain ± SEM). (C) Quantification of total number of microglia isolated per hemisphere. (D) Quantification of the number of CD11b+ cells associated per plaque ≥75 μm in diameter. (E) Representative micrographs of plaques (green) and microglia (brown) in PS1-APP and PS1-APP-CX3CR1+/− mice. For all measurements in this figure, n = 6 for PS1-APP, n = 7 for PS1-APP-CX3CR1+/−. For (E) 80 plaques were counted per genotype. * represent statistically significant.
