Neuroligin mutation triggers oxidative stress

by  /  20 October 2009

Deleting a neuronal protein associated with autism causes oxidative stress — characterized by an excess of free radicals — which has been linked to diseases such as diabetes and Alzheimer’s, according to new research in worms. The results were presented yesterday at a poster session at the Society for Neuroscience meeting in Chicago.
