Erratum

The original article [1] contains an error in the y-axes of Fig. 10a & b – the accidental omission of a μ symbol preceding the denoted units for both graphs means that incorrect units are displayed.
Figure 1
Fig. 10

Adult-only lead exposure results in elevated blood lead levels and lead deposition in the brain. 8-week-old ApoE3- KI and ApoE4-KI male and female mice were exposed to 0.2% lead acetate for 12 weeks and then sacrificed. Blood and one brain hemisphere were collected at sacrifice and (a) blood lead and (b) brain lead levels were measured using ICPMS. Brightfield images of one brain hemisphere from a female (c) control and (d) lead-treated ApoE4-KI mouse after the 12 week lead exposure. Semi-quantitative measurement of lead in the brain of a (e) control and (f) lead-treated ApoE4-KI mouse using LA-ICP-MS. Two-way ANOVA with Fisher’s LSD post-test: n.s., not significant; ** p < 0.01; *** p < 0.001. Scale bars, 100 μm

As such, the authors would like to note that the correct units are μg/dL for Fig. 10a and μg/g for Fig. 10b.

The correct version of this figure is displayed below for reference too.
