Direct evidence that polysorbate-80-coated poly(butylcyanoacrylate) nanoparticles deliver drugs to the CNS via specific mechanisms requiring prior binding of drug to the nanoparticles.

TLDR
There is little in vivo or in vitro evidence to suggest that a generalized toxic effect on the BBB is the primary mechanism for drug delivery to the brain, and the fact that dalargin has to be preadsorbed onto nanoparticles before it is effective in inducing antinociception suggests specific mechanisms of Delivery to the CNS.
Abstract
Purpose. It has recently been suggested that the poly(butylcyanoacrylate) (PBCA) nanoparticle drug delivery system has a generalized toxic effect on the blood-brain barrier (BBB) (8) and that this effect forms the basis of an apparent enhanced drug delivery to the brain. The purpose of this study is to explore more fully the mechanism by which PBCA nanoparticles can deliver drugs to the brain.

An easier, reproducible, and mass-production method to study the blood-brain barrier in vitro.

TL;DR: This work has developed a process ofoculture that closely mimics the “in vivo” situation by culturing brain capillary endothelial cells on one side of a filter and astrocytes on the other, and which is impermeable to inulin and sucrose but allows the transport of leucine.

Passage of peptides through the blood-brain barrier with colloidal polymer particles (nanoparticles)

TL;DR: Fluorescent and electron microscopic studies indicated that the passage of the particle-bound drug occurred by phagocytic uptake of the polysorbate 80-coated nanoparticles by the brain blood vessel endothelial cells.

Significant transport of doxorubicin into the brain with polysorbate 80-coated nanoparticles

TL;DR: It is demonstrated that the brain concentration of systemically administered doxorubicin can be enhanced over 60-fold by binding to biodegradable poly(butyl cyanoacrylate) nanoparticles, overcoated with the nonionic surfactant polysorbate 80.

Delivery of loperamide across the blood-brain barrier with polysorbate 80-coated polybutylcyanoacrylate nanoparticles.

TL;DR: Polysorbate 80-coated PBCA nanoparticles loaded with loperamide enabled the transport of loperamia to the brain and induced a much less pronounced and very short analgesia.
