Alzheimer's disease reversed in mice, offering hope for humans

Sharing is Caring!

“Remarkable” — that’s how researchers are describing the results of a new study done on mice displaying traits associated with Alzheimer’s disease.
The deletion of just a single enzyme saw the near total reversal of the deposition of amyloid plaques found in brains of those with Alzheimer’s, improving cognitive functions in the mouse subjects, according to the study from researchers at the Cleveland Clinic, published Feb. 14 in the Journal of Experimental Medicine.
These promising research findings center around deleting a gene that produces an enzyme called BACE1, which helps make the beta-amyloid peptides that accumulate abnormally in the brains of people with Alzheimer’s disease. Studies have shown that stopping or reducing that enzyme’s activity dramatically reduces production of beta-amyloid peptides, which are toxic to the brain and lead to the symptoms — including memory loss — associated with Alzheimer’s.
