Figure 6.

Uptake of propidium iodide-labeled pLXSN-CGRP by hCMEC/D3 cells incubated with naked propidium iodide-labeled pLXSN-CGRP, propidium iodide-labeled GS NP-pLXSN-CGRP, and propidium iodide-labeled Tat-GS NP-pLXSN-CGRP for 11 hours, as determined by flow cytometry.

Notes: Values are expressed as the mean ± standard deviation (n = 4). *P < 0.01 versus naked propidium iodide-labeled pLXSN-CGRP.

Abbreviations: ND, naked DNA (pLXSN-CGRP); GS, gelatin-siloxane nanoparticles; Tat-GS, Tat peptide-decorated gelatin-siloxane nanoparticles.
