Genetically modified cells reverse the effects of Alzheimer's disease in rats.

Biomedical researchers at the Harvard Medical School have made an interesting discovery while working with rats that had, for all intents and purposes, developed Alzheimer's disease - genetically modified rat cells that produce a protein that breaks up amyloid-beta plaques in the brain can reverse the progression of the disease. At least in part (thus disclaimed because this isn't really my field of expertise), Alzheimer's disease is caused by masses of a protein called amyloid-beta that interfere with the normal operation of neurons in the brain, causing the functionality of neural networks to degrade. There is, however, a protein called neprilysin …
