The researchers, including Dr. Jeffrey Zigman, associate professor of internal medicine and psychiatry at UT Southwestern, say they have uncovered an important mechanism by which ghrelin - a natural antidepressanthormone - works inside the brain.

In addition, the team has uncovered a neuroprotective drug that they say has the potential to be a powerful treatment fordepression.
