Red wine compound may help treat depression and anxiety

Washington DC: A compound called resveratrol found in red wine displays anti-stress effects by blocking the expression of an enzyme related to controlling stress in the brain, a recent study has claimed.
The study published in the journal 'Neuropharmacology' sheds light on how resveratrol impacts neurological processes.
"Resveratrol may be an effective alternative to drugs for treating patients suffering from depression and anxiety disorders," said Ying Xu, co-lead author of the study.
Resveratrol, which has been linked to a number of health benefits, is a compound found in the skin and seeds of grapes and berries.
While research has identified resveratrol to have antidepressant effects, the compound's relationship to phosphodiesterase 4 (PDE4), an enzyme influenced by the stress hormone corticosterone, was unknown.Corticosterone regulates the body's response to stress. Too much stress, however, can lead to excessive amounts of the hormone circulating in the brain and, ultimately, the development of depression or other mental disorders.
These unknown physiological relationships make drug therapy complex. Current antidepressants instead focus on serotonin or noradrenaline function in the brain, but only one-third of patients with depression enter full remission in response to these medications, said Xu.
In a study on mice, researchers revealed that PDE4, induced by excessive amounts of corticosterone, causes depression- and anxiety-like behaviour.The enzyme lowers cyclic adenosine monophosphate -- a messenger molecule that signals physiological changes such as cell division, change, migration and death -- in the body, leading to physical alterations in the brain.
Resveratrol displayed neuroprotective effects against corticosterone by inhibiting the expression of PDE4. The research laid the groundwork for the use of the compound in novel antidepressants. (ANI)
