MIT finds cure for fear

MIT biochemists have identified a molecular mechanism behind fear, and successfully cured it in mice, according to an article in the journal Nature Neuroscience.

Researchers from MIT's Picower Institute for Learning and Memory hope that their work could lead to the first drug to treat the millions of adults who suffer each year from persistent, debilitating fears - including hundreds of soldiers returning from conflict in Iraq and Afghanistan.

Inhibiting a kinase, an enzyme that change proteins, called Cdk5 facilitates the extinction of fear learned in a particular context, Li-Huei Tsai, Picower Professor of Neuroscience in the Department of Brain and Cognitive Sciences, and colleagues showed. Press Esc
