Oregon State University researchers have discovered a way to get anti-inflammatory medicine across the blood-brain barrier, opening the door to potential new therapies for a range of conditions, including Alzheimer’s disease, multiple sclerosis, Parkinson’s disease and cancer cachexia. (The blood-brain barrier is a protective shield separating the brain from the bloodstream; it is made up of tightly packed cells lining the blood vessels in the brain and controls what substances can move from the blood to the brain.) The delivery method involves specially engineered nanoparticles. Tested in a mouse model, the nanoparticles reached their intended destination, the hypothalamus, and delivered a drug that inhibits a key protein associated with inflammation.
