Evaluation of uptake by and transport across BMEC monolayers of liposomes at different times. Quantification of Lipo and gH625-Lipo loaded at 5 µM PACAP-Rho in different compartments of the in vitro BBB model after incubation in the luminal compartment in contact with BMEC monolayers for 30, 60 and 120 min at 37 °C. (A) Amounts of PACAP-Rho in the luminal compartment; (B) PACAP-Rho in the BMEC lysate; (C) PACAP-Rho in the abluminal compartment. Values represent means ± SD of 5 independent experiments (*P < 0.05; **P < 0.005; ***P < 0.0005).
