Brain Cell 'Executioner' Identified

Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and even such neurodegenerative diseases as Alzheimer's. Now, researchers at Johns Hopkins say they have pinpointed the protein at the end of that chain of events, one that delivers the fatal strike by carving up a cell's DNA. The find, they say, potentially opens up a new avenue for the development of drugs to prevent, stop or weaken the process.
