Engineering Delivery Systems to the Brain

Engineering a ‘Trojan horse’ to sneak drugs into the brain by Terry Devitt:

Using engineered yeast as microscopic factories to produce human antibodies customized to recognize the surface features of cells that compose the blood-brain barrier, Shusta has developed a set of unique antibodies that may one day be used to ferry drugs to specified regions of the brain.

With roughly 400 miles of blood vessels, the human brain is equipped with its own expansive delivery network for therapy – provided scientists are able to figure out a way to get past the blood-brain barrier. With different cell surface features in different parts of the circulatory system and also in different regions of the brain, it might be possible to customize antibodies to carry drugs to only those parts of the brain that would benefit from treatment.
