Repeated defeat by dominant animals leaves a mouse with an enduring ‘molecular scar’ in its brain, University of Texas scientists found. Thus the researchers might explain now why depression is so difficult to cure! The research is funded by the National Institute of Mental Health.



Silencer molecules turned off a gene for a key protein in the brain’s hippocampus, the scientists discovered. Though failed to remove the silencers that are thought to remain as a latent source of vulnerability to future depression-like responses to stress, antidepressants compensated for the resulting social avoidance syndrome.
