Alzheimer protein seems to slow down neurotransmitter production

Researchers report how abnormal protein deposits in the brains of Alzheimer's patients disrupt the signaling between nerve cells. They varied the amount of APP protein and related proteins associated with Alzheimer's disease in cell cultures, and then analyzed how this manipulation affected other proteins in the cell. The result: The amount of APP present was related to the amount of an enzyme that is essential for the production of neurotransmitters and therefore for communication amongst nerve cells.
