Alzheimer's may start in liver
"The protein that forms plaques in the brains of people with Alzheimer's disease may have its origins in the liver, a new study in mice suggests.
The researchers said that targeting the liver's production of this protein, called beta amyloid, may be a new way to treat Alzheimer's.
In fact, the researchers tested their theory by treating mice with a drug that could not cross the blood-brain barrier and enter the brain. They found the drug significantly reduced levels of beta amyloid in both the blood and the brain. This suggests a considerable amount of beta amyloid found in the brain is produced elsewhere, they said.
The researchers were surprised by their findings."
