"This is the first study to show that [the compound] Cu(ATSM) can increase the abundance of P-gp clearance pumps in an Alzheimer's model, by 24.1 percent, effectively linking the repair of the blood-brain barrier to a reduction in toxic proteins and improved cognitive function," Dr. Pyun said.

"By improving the pumps, the brain can finally clear out the trapped waste. Over 56 days, the treatment reduced toxic amyloid-beta by 42 percent and improved spatial learning by nearly 44 percent."

"Cu(ATSM) is a copper compound with anti-inflammatory and neuroprotective properties that has already progressed to clinical testing for conditions like Parkinson's and ALS," Professor Nicolazzo said.
