In lab experiments, University of Manchester researchers found that brain cells infected with HSV-1 had increased levels of beta amyloid protein, which creates the plaques found in the brains of Alzheimer's patients.
The findings appeared in New Scientist magazine.
In other experiments, the researchers found that the brains of mice infected with HSV-1 showed increased levels of beta amyloid, and that HSV-1 was attached to the plaques found in the brains of dead Alzheimer's patients.
Previous research found that HSV-1 is present in the brains of up to 70 percent of Alzheimer's patients, BBC News reported.
This line of research may help in the development of a vaccine to prevent Alzheimer's, but any such breakthrough is a long way off, experts say. – (HealthDay)
