Last year, we reported that researchers at the University of Virginia School of Medicine made the breakthrough discovery that the immune system and the brain are not isolated from one another as previously thought, but connected through a system of lymphatic vessels. The astonishing discovery of a “new” part of the human body opened the door to new ways of looking at immunity. Now, building on that research, the same team has made a potentially even more startling breakthrough: The immune system may play a key role in controlling and shaping social behavior. Their results were published recently in the journal Nature.
