Drug delivery is often inhibited by the blood-brain barrier that protects the brain. However, now a new study may have gained insight into how to 'trick' this part of the body in order to make it easier to treat many of the diseases of the central nervous system. The study was focused on so-called nanoparticle liposome drug carriers, which act like a Trojan Horse, making it simpler to allow drug delivery to the brain without the blood-brain barrier getting in the way. This development could have vital implications for diseases of the nervous system, including Parkinson's, Alzheimer's and Sclerosis. This is one of the first studies to establish that nanoparticle entry to the brain is possible and to show why, when and where it happens. Researchers used two-photon imaging to deconstruct the blood-brain barrier to understand how nanoparticles interact with it. This kind of innovation is only possible through building the kinds of exceptional teams that come from great technology and pharmaceutical research & development recruitment.
