Ghrelin has also bee looked at for controlling weight gain and Type II diabetes....
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.
To reach their findings, recently published in the journalMolecular Psychiatry, the researchers began by analyzing ghrelin in mice models. Ghrelin is referred to as the "hunger hormone," as it is known for its ability to arouse appetite.
