According to the journal's portal Very interesting experts from the United Kingdom, Poland and Japan discovered that a protein in the brain is responsible for the anxiety resulting from stress. This information was originally published in the journal Nature.
Robert Pawlak , who directs the research at the University of Leicester (in Great Britain), notes that "until now it was known that certain individuals are more susceptible to the damaging effects of stress than others: although most people experience some traumatic event in your life, only some develop psychiatric problems as depression, anxiety or post-traumatic stress disorder. "
In the study it is reported that the determining factor of these differences could be in the emotional center of the brain, the amygdala, which reacts to stress by increasing the production of a protein called neuropsin. This protein triggers a series of chemical reactions that, in turn, they make the Amygdala increase its activity .
The conclusion of the experts is that the activity of neuropsin and other related molecules determines the susceptibility to stress. "We know that all components of the neuropsin pathway are present in the human brain , so they should play a similar role, "said Pawlak.
It is hoped that this research will favor the development of new drugs to prevent anxiety and depression.
