Scientists have discovered that a gene linked to Alzheimer’s disease may play a beneficial role in cell survival by enabling neurons to clear away toxic proteins. A study funded by the National Institute on Aging (NIA), part of the National Institutes of Health, shows the presenilin 1 (PS1) gene is essential to the function of lysosomes, the cell component that digests and recycles unwanted proteins. However, mutations in the PS1 gene — a known risk factor for a rare, early onset form of Alzheimer’s disease — disrupt this crucial process.

The study, led by scientists at National Cancer Institute (NCI), part of the National Institutes of Health, and their colleagues, appeared online April 1, 2010 and in print April 16, 2010, in the journal Cell....
