Research was undertaken to establish transplacental delivery of active genes to fetal brain by a non-viral vector, antibody-specific targeted therapeutic procedure. PEGylated immunoliposomes (PILs) containing firefly luciferase DNA under the influence of the SV40 promoter injected intravenously into near-term pregnant mice produced luminometric evidence of CNS tissue luciferase activity at 48-h post-injection in all newborn pups. In utero delivery of this pGL3 DNA was shown after a single i.

Immunogold electron microscopy has identified a variety of blood-brain barrier (BBB) proteins with transporter and regulatory functions. For example, isoforms of the glucose transporter, protein kinase C (PKC), and caveolin-1 are BBB specific. Isoform 1 of the facilitative glucose transporter family (GLUT1) is expressed solely in endothelial (and pericyte) domains, and approximately 75% of the protein is membrane-localized in humans.
