Natural birth may strengthen immune system, mouse study shows

10 julio 2014

New knowledge about the immune system has been uncovered by a mouse study, which indicates that natural birth improves the immune system of the pups. Newborns delivered by natural birth are exposed to more bacteria from the mother. The newborn baby’s immune system in this way learns to distinguish between its own harmless molecules and foreign molecules. In the experiment, pups delivered by Caesarean section showed a lower number of cells of a type that plays an important role in preventing reactive immune cells from responding to molecules from the body itself, from the diet and from harmless intestinal bacteria.
