London: Scientists have found the brain`s most miserable molecule - a protein involved in all our feelings of stress, anxiety and depression - paving way for development of new drugs to control it. Researchers used the Diamond Light Source, a particle accelerator at Harwell in Oxfordshire, which generates some of the world`s most powerful x-ray beams, to study molecules that jut from the outer surfaces of cells in the brain`s pituitary gland. It is already known that the pituitary plays a crucial role in anxiety and depression by releasing stress chemicals into the blood. However, it was not known how the response was triggered, although a protein named CRF1 was a suspect.
