Novel Approach to Prevention of Alzheimer’s Disease Explored in Laboratory (Express / PloS One)

Summary

Researchers at the University of California, San Diego, have explored a different approach to mainstream research into the prevention of Alzheimer’s Disease. It is believed that Alzheimer’s Disease develops when amyloid precursor protein (APP) gets cut-up by enzymes and forms beta-amyloid (ß-amyloid). This ß-amyloid build-up results in, or is associated with, Alzheimer’s Disease.

The San Diego research team developed ten proteins with the ability to bind to APP. Four of these proteins stopped the APP being cut up; and one in particular, called P8, had the strongest effect. Infusing P8 into the brains of mice genetically engineered to develop a form of Alzheimer’s resulted in a significantly reduced level of ß-amyloid production. Tests along the same lines, using human brain cells in laboratory culture dishes, yielded similar results.

This promising line of new research is, of course, at an early stage
