A potential Alzheimer's Disease treatment is showing much promise. 

UC Irvine professor Matthew Blurton-Jones said specially-bred mice showed great improvement when treated with genetically-modified stem cells.

"We specifically were focused on the pathology ... and what we saw was a very dramatic reduction in that pathology when the animals received these cells," he said. 

Blurton-Jones says the modified cells produced an enzyme that broke down plaques in the brain.  

The study results are in the journal "Stem Cell Research and Therapy."
