Protein may regulate depression

Scientists say they have pinpointed a protein which they believe may play a pivotal role in depression.

A team from Rockefeller University in New York found mice deficient in the protein - p11 - showed signs of depression-like behaviour.

In contrast, raising levels was shown to have an anti-depressant effect on the animals.

Writing in the journal Science, they say p11 appears to help regulate a brain chemical linked to mood.

However, a UK expert said the biochemical regulation of depression was likely to be complex.
