The immune system responds to the appearance in the body of pathogenic bacteria and viruses within a few minutes after they enter the tissues. To such a rather unexpected conclusion came the scientists from the University of Dundee in the UK, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. Net Previously, it was believed that the immune response develops only a few hours after infection, and all this time the body remains completely defenseless against infections.

But scientists managed to prove that in fact the first signs of activation of the immune system appear almost immediately after the penetration of microorganisms.

The immune response begins with the reaction of the so-called dendritic cells, which are contained in virtually all tissues of the body and carry on their surface specific receptors that react to certain components of bacteria. When these receptors are activated, dendrites carrying bacterial proteins on their surface begin to migrate to the lymph nodes, causing a general reaction from the immune system.
