Skin immune layer of the body

On our skin has more bacteria than in our gut, an international team of scientists based in Sydney, says that on the outer layers of the skin is a set of immune cells, which protects people from the sharp response of friendly bacteria.

A team of scientists led by Professor Barbara Fazekas de St. Groth found that immune cells in the outer layer of the skin play the role of peacemakers, stopping the immune system from responding to various bacteria, which will not cause harm to humans. Known as Langerhans cells, they resisted all attempts of scientists to induce an immune response. It turned out that these cells are responsible for immune tolerance to a large number of bacteria.

This discovery may become the underlying in the problem of treatment of immune diseases, especially inflammatory bowel disease.
