Fig. 3From: Dual effect of TAT functionalized DHAH lipid nanoparticles with neurotrophic factors in human BBB and microglia culturesNLC modified transport across BMCEs A TAT-CS-NLC-DiD successfully penetrate the BMEC monolayer as opposed to the CS-NLC-DiD. (Data are means ± SEM of three independent experiments, p < 0.01 **, One-sample t-test analysis) B Representative images of the BMEC monolayer after treatment with our NPs. Blue shows the nuclei stained with DAPI, green shows the tight junctions stained with ZO-1, whereas the NLCs are shown in magenta (incorporated DiD). TAT-CS-NLC-DiD could be detected in our cell monolayer, while CS-NLC-DiD were not detectable. The images show the maximum intensity projection of a Z stack. Scale bar 50 µmBack to article page
