If My Cells Can Live Forever, Does That Mean I Can, Too?

An article in Technology Review looks into recently published research that found a cell survival switch in mitochondria that could one day be a drug target to prevent cell death in people with diseases like Alzheimer's. Led by scientists at Harvard Medical School, the work found that by turning up expression of NAMPT, a mitochondrial enzyme, increased longevity of cells. "The findings could provide a new set of targets for drugs to treat the diseases related to aging, including Alzheimer's and diabetes," the article says.
