Is Alzheimer's transmissible? Mouse study hints it's possible
A brain protein linked to Alzheimer's disease might potentially be transmitted to people during neurological procedures, a new preliminary study suggests.
Genetically engineered lab mice developed amyloid-beta deposits in their brains after they were injected with amyloid-laced samples of human growth hormone taken from decades-old human cadavers, researchers found.
"We have now provided experimental evidence to support our hypothesis that amyloid-beta pathology can be transmitted to people from contaminated materials," said senior researcher Dr John Collinge. He is head of University College London's department of neurodegenerative disease.
