Inhaling microbes, the pregnant woman cares about health of the future child, scientists by results of researches have declared.

Researchers assert, that thanks to more frequent penetration into an organism of microbes the load of toll-like receptors of mother (TLR) and as consequence - manufacture of molecules of cytokines is enlarged. Role TLR in protection of an organism against an allergy is very high, however scientists have not understood yet how signals from these receptors enlarge resistibility to an allergy among little mice.

Scientists observed of the pregnant mouse which inhaled air containing a considerable quantity of various microbes. Then at it little mice with the raised fastness to allergies were born. As to microbes in an organism of mother they caused only insignificant inflammatory processes.

Earlier researchers already have established, that children who have been grown up in a countryside (where mothers adjoin to various microbes is much more often) suffer from an allergy, than their city coevals much less often. There is a theory that early contact with microbes of the rural child leads to strengthening of its immune system. It develops resistance to allergies on for the rest of the life.
