Copper-delivery drug boosts brain cleanup and memory in Alzheimer's mouse model

Monash University researchers used Cu(ATSM), a copper-delivery compound, to repair the brain’s blood–brain barrier by increasing the P-glycoprotein clearance pumps, which reduced toxic amyloid-beta by about 42% and improved long-term spatial memory by roughly 44% in an APP/PS1 mouse model over 56 days, suggesting copper-based biometal therapy could be a promising route for early symptomatic Alzheimer's disease with potential for quicker human testing due to prior safety evaluations; future work aims to map the precise clearance mechanisms and pathways.
