L-thyroxine (T4) inhibition of Abcg4-mediated efflux of [3H]Aβ1–40 and [3H]desmosterol at the mouse BBB level. Efflux ratio of [3H]desmosterol (Panel A) or [3H]Aβ1–40 (Panel B) obtained by dividing the brain uptake clearance (Clup, µL/g/s) measured in the presence of T4 (10 µM) over the Clup measured in the absence (Ctrl) of T4 (ERT4/ctrl) in WT and Abcg4-KO mice. Data are means ± S.D. of 5–8 mice. *p < 0.05 (two-way ANOVA analysis followed by a Bonferroni post-test).
