Scientists found the cause of frequent infectious diseases in children

A well-known fact that children are most frequent infectious diseases more difficult to tolerate. We can say that their body attracts viruses and bacteria. The situation is more complicated and still weak bodies. This fact limits the use of drugs, including antibiotics. Before scientists figured out why many infections are amazing, first of all, children.

It turns out, it's immature immune system of the child. As children do not have time to Mature immune cells. The data were confirmed after a series of experiments on laboratory mice and monitoring the health status of children suffering from infectious diseases.

The first days of life is a special period when the child's body tries to adapt to new environmental conditions. This period is associated with depression of immunity for faster adaptation of the useful flora. However, this fact in hand and pathogenic microbes.

In the study, researchers transplanted immune cells from newborn rats. Transplant was unsuccessful, and the cells themselves instantly lost its activity. The result was repeated during the experiment in vitro when cells in the blood of a newborn animal is contacted with cells of adult rats.

It should be noted that the reverse transplant from a young mouse to adult was normal. In-depth study in this area showed that in the case arginase-2. This enzyme suppresses the immune properties of cells.
