Brain-targeted polymeric nanoparticles: in vivo evidence of different routes of administration in rodents

Nanomedicine (Lond). 2013 Sep;8(9):1373-83. doi: 10.2217/nnm.12.172. Epub 2013 Apr 8.

Abstract

AIMS, MATERIALS & METHODS: The capacity of polymeric nanoparticles (NPs) to reach the target regardless of the administration route is a neglected field of investigation in pharmaceutical nanotechnology. Therefore, after having demonstrated in previous studies that glycopeptide-engineered NPs (g7-NPs) were able to reach the brain after intravenous administrations in rodents, this article aims to evaluate whether they can reach the CNS when administered by different routes.

Results & conclusions: The confocal microphotographs on murine brain sections showed the capability of g7-NPs to reach the target also after intraperitoneal, intranasal and oral administrations. This could open new vistas for the future application of g7-NPs in the therapeutic treatment of CNS diseases.
