Sclerosis, Parkinson's Disease, Alzheimer's and epilepsy are but a few of the central nervous system disorders. They are also very difficult to treat, since the brain is protected by the blood-brain barrier.
The blood-brain barrier works as a border wall between the blood and the brain, allowing just certain molecules to enter the brain. And whereas water and oxygen can get through, as can other substances such as alcohol and coffee. But it does block more than 99 percent of potentially neuroprotective compounds from reaching their targets in the brain.
Now, in a study conducted in living, including awake mice, a team of researchers from the University of Copenhagen provides direct insight on how to trick the blood-brain barrier's impermeable walls to allow drug delivery to the brain.
