Trial Drug Could Clear Toxic Alzheimer's Proteins and Restore Memory
Summary
Scientists at Monash University found that a copper-based drug called Cu(ATSM) reduces toxic proteins linked to Alzheimer’s disease and improves memory in lab studies. The drug appears to help the brain clear waste by restoring the function of a protective barrier and its waste-removal pumps.Key Facts
- Cu(ATSM) lowered levels of amyloid-beta, a harmful protein linked to Alzheimer’s, by 42% in lab tests.
- The drug improved long-term spatial memory by nearly 44% in the same studies.
- It works by increasing the number and activity of P-glycoprotein pumps that remove waste from the brain.
- These pumps are part of the blood-brain barrier, which becomes less effective in Alzheimer’s patients.
- Cu(ATSM) has already been tested for safety in other brain diseases like Parkinson’s and ALS.
- The treatment improved the function of brain blood vessels, helping clear toxic proteins.
- Researchers believe fixing this waste-clearance system could slow or reverse Alzheimer’s damage.
- Scientists are still studying exactly how the brain removes these proteins once the barrier is repaired.
