In the cozy world of sterile womb, the fetus is protected from attack
infectious. In pregnant women, maternal cells enter the body of
fetus, allowing the immune system learns to tolerate rather than attack
as he would later for any foreign body.
This tolerance helps explain why during transplants, patients tend to tolerate more
tissues similar to those of their mothers.
Scientists at the Pasteur Institute and CNRS revealed in "Nature Immunology "
the establishment of an immune system so to regulate the development of the intestinal flora at birth.
They noted the presence of white blood cells from the family lymphocytes.
Scientists speak of players of innate immunity.
What are these atypical lymphocytes?
The ILC release two molecules, interleukins 17 and 22 which will regulate the establishment
intestinal flora.
This discovery opens a path to understanding autoimmune diseases as
Crohn's disease (chronic inflammation of the instin).
