It became known as stress destroys your immune system

Стало известно, как стресс разрушает иммунную систему

Scientists have found that stress worsens the General condition of the body, and permanent psychological pressure can cause serious somatic diseases.

But the exact mechanism of this process until now was not well understood.

University staff name Bar-Ilan (Israel) conducted a special study and established a certain pattern. Stress caused a change in the intestinal bacteria, which, in turn, stimulated the activity of immune cells, and they often start to attack healthy body tissues, according .

“What is our life? Game!”Стало известно, как стресс разрушает иммунную систему“World mind games”: the premiere of “the World” To treat autoimmune diseases such as multiple sclerosis, lupus, rheumatoid arthritis, type I diabetes, scleroderma and pulmonary fibrosis. Only in the US, these diagnoses are about 20 million people, mostly women.

The main risk factor is considered to be a bad heredity. But many experts believe that the development of disease is influenced by genetics and external adverse conditions.

It is already known that between the immune system and the gut microbiota there is a strong correlation.

An important step in understanding how stress can lead to autoimmune disorders – the identification of genetic responses of bacteria, said the authors of the study.

According to them, social stress alters the composition and properties of the microbiota, and the subsequent immune response to this threat is a danger to the whole organism.

Scientists conducted an experiment with two groups of mice. Some were subjected to daily stress, meeting with other rodents, strong and aggressive. Others lived in a peaceful atmosphere.

After 10 days it turned out that the mice from the first group increased the amount of certain bacteria such as Bilophila and Dehalobacterium – their abundance is characteristic for the patients with multiple sclerosis.

Also experts have noticed that under stress in bacteria aktiviziruyutsya genes associated with potentially dangerous manifestations, including growth, mobility and intensity of the signals between the pathogen and the host.

These germs can migrate throughout the body and settle, for example, in lymph nodes, causing an immune response.

Earlier it was reported that a strong stress is bad for the heart.
