(A) Experimental outline (see Methods for additional details).
(B) IBA1+ microglia from B6.APP/PS1 TG control and PLX5622 mice (left). Quantification of IBA1+/DAPI+ microglia across CA1 lamina (right). Datapoints represent individual mice; error bars are ± SD; asterisks denote comparisons (p<0.05) identified between control and PLX5622 groups (right) after corrections for multiple comparisons. SLM, stratum lacunosum moleculare; SR, stratum radiatum; SO, stratum oriens.
(C) X34+ Aβ plaques in B6.APP/PS1 TG control and PLX5622 mice (left). Quantification of X34+ Aβ plaque area across CA1 lamina (right), plotted as described above.
(D) Quantification of IBA1+ area from SLM defined as plaque-associated (PAM) or non-plaque associated microglia (NPAM). Points represent mean values calculated for individual mice and analyzed with two-tailed nonparametric t-tests.
Statistical analyses performed on B6 and PWK separately. For (B)-(C) *adjusted p<0.05 Bonferroni post-hoc tests. For (D) *p<0.05 nonparametric two-tailed t-test (Table S2).
