An international team of researchers has reported a striking Alzheimer's breakthrough in mice using specially engineered nanoparticles that do much more than deliver medicine. These microscopic particles act as drugs themselves, helping the brain restore its own natural cleaning system and dramatically reducing toxic protein buildup linked to Alzheimer's disease.
The work was led by scientists from the Institute for Bioengineering of Catalonia (IBEC) and West China Hospital Sichuan University (WCHSU), together with collaborators in the United Kingdom. Their findings were published in Signal Transduction and Targeted Therapy.
Instead of focusing directly on damaged neurons, the scientists targeted the blood-brain barrier (BBB), a protective network of cells and blood vessels that controls what enters and leaves the brain. In Alzheimer's disease, this system gradually breaks down, allowing harmful proteins to accumulate and damaging brain function over time.
The researchers designed bioactive nanoparticles called "supramolecular drugs" to help restore this barrier and restart the brain's ability to remove waste.
