Effect of KBs on Aβ transport across BBB. (A) Schematic representation of the human in vitro BBB model used for (A) apical-to-basolateral (red arrow) and (C) basolateral-to-apical (green arrow) Aβ transport. After 48 h of treatment with KBs, Aβ1–40Cy5 or [3H]inulin was added to the (B) apical compartment or (D) basolateral compartment, incubated for 30 min, and permeability was then assessed. The data represent the mean ± SEM obtained from at least three independent experiments relative to the control conditions, each of which was performed in triplicate (*** p < 0.001).
