Brain depression molecule discovered

Scientists have identified the molecule that is believed to be responsible for feelings of depression.

One of the world's most powerful x-ray machines has been used to discover the CRF1 protein receptor which is thought to be responsible for feelings of anxiety and depression over long periods of time. It works in relation to the hypothalamus, releasing hormones as and when it detects stress molecules. The research should help in the development of new and more effective anti-depressants.

"Now we know its shape, we can design a molecule that will lock into this crevice and block it so that CRF1 becomes inactive - ending the biochemical cascade that ends in stress," said scientist Dr Fiona Marshall.

"Scientists have used one of the world’s most powerful X-ray machines to identify the molecule responsible for feelings of stress, anxiety and even depression."

Sounds better than ECT. I hope they find a way to make what they have discovered work.

Huh. I realize that the suggested treatment modality from this ground-breaking finding is preliminary, and will likely take a few years to develop an appropriate drug to do the "lock" As an acute anxiety sufferer myself, I have had no joy on numerous antidepressants, and actually have had many bad side-effects. Because of that, what seems to work for me is mild CNS "sedation", be it through my prescribed benzo's or a good, cold beer.

Very interesting I think that depression and OCD for instance are literally a malefunction and I am hopeful if it can be efficently managed through a medication that can fix the problem and not only freeze your brain. Not that anxiety and sadness are anormal, but states of overanxiety and oversadness which repeat itself over and over again is a problem. You find yourself out of work and unable to fonction properly in the society. Meditation and other pastime can kee... [More]
