Dirt immunity and “pig happiness”

Smearing the mud can be useful not only for the immune system, but also to set the mood. So say British researchers.

There are many stories about how “healthy bacteria” that live usually in the ground, supposedly helping to feel again the taste of life people with the most serious diseases, including lung cancer. And here experts from the University of Bristol decided to test whether these stories are true. And began to treat these same bacteria of mice.

As a result, according to scientists using a specialized journal of Neuroscience, revealed: in the brain of these animals produces more serotonin.

Interestingly, the effect of modern antidepressants based on strengthening the production organism, precisely this “happy” substance. A lack of serotonin, scientists believe, causes people depression.

Bristol, experts agree: it is too early to clearly say that the bacterium Mycobacterium vaccae, stimulating the neurons of serotonin, a natural antidepressant, in this direction still need to work.

“This study contributes to our understanding of how the body communicates with the brain and why a healthy immune system is so important to maintain mental health, says Dr. Chris Lowery, who led the experiment. – So we need to seriously consider whether all of us often wallow in the mud”.

Dr. Lowry and his colleagues, he says, also helps to understand why the imbalance of the immune system leads to the fact that a person becomes vulnerable to experiencing depression and mood swings.

Research in this area carried out by canadian scientists.

At Georgetown University recently revealed that serotonin is passed between key cells of the immune system, and also the fact that this substance has the ability to activate the body’s immune response to a particular event.

This suggests that serotonin is able to restore a healthy immune system in people who suffer from depression and easily infected various infections.

On the other hand, it is also possible that serotonin, and based on its activation antidepressants – can so activate the immune system that turns on “autoimmunity”, and the body begins to attack itself.

“We don’t yet know how these drugs affect the immune system, – says a leading canadian researcher Gerard Ahern, so we need to figure out what the role actually being played by serotonin in the functioning of immune cells.”
