Autism gene stunts neurons, but growth can be restored, in mice

Brown University researchers have traced a genetic deficiency implicated in autism in humans to specific molecular and cellular consequences that cause clear deficits in mice in how well neurons can grow the intricate branches ...

New study confirms immune cells are guided by gradients

(Medical Xpress)—A group of researchers in Austria and Switzerland has for the first time proven that immune cells migrate along chemical concentration gradients. This process has long been assumed but never demonstrated ...
