The study highlights an amazing change that takes place in a mother’s body when she begins producing breast milk. For years before her pregnancy, cells that produce antibodies against intestinal infections travel around her circulatory system as if it were a highway and regularly take an “off-ramp” to her intestine. There they stand ready to defend against infections such as cholera or rotavirus. But once she begins lactating, some of these same antibody-producing cells suddenly begin taking a different “off-ramp,” so to speak, that leads to the mammary glands.
