The bad character removes the depression

They discover that a bacterium of active floor to the group of neurons that produce the cerebral compound of the serotonin.

The treatment in mice with this innocuous bacterium that are usually in the floor, altered your behavior in a very similar form to which are gotten with drugs antidepreseivos, such and like the investigators informed in the last edition of Neuroscience.

These discoveries, identified by investigators of the University of Bristol and your colleagues of University College of London, help to understand why an unbalance in the immune system takes to that some vulnerable individuals suffer such dysfunctions of humor as the depression.

The physician Chris Lowry, main author of the work carried out by the University of Bristol commented: "These studios help us to understand how you communicate the body with the brain and why you are important to have a healthy immune system for the mental health maintenance. You also take us to wonder if more time should not pass playing among the dirt."

The interest in the project arose after some human patients of cancer tried with the bacterium Mycobacterium vaccae experience an enhancement unexpectedly in your quality of life. Lowry and your colleagues reasoned that this effect would putrefy book credit been caused by the activation of the neurons in the brain that they contain the serotonin.

When the team observed the brain of the mice detailedly, you discovered that the treatment with M. vaccae had activated to the group of neurons in charge of producing the compound cerebral chemical called serotonin. You are believed that the serotonin ullage in the brain is the lawsuit of the depression in people, for that reason the goods of M. vaccae in the behavior of the mice could be due to an increase in the serotonin release in the parts of the responsible brain of regulating the humor.

The new investigation supports this hypothesis, but in the future new studios will be designed routed to determine if M. vaccae, another bacterium, or some compound pharmaceutic possesses antidepressant estates that work by means of the activation of this group of neurons of the serotonin.
