> Scientists uncover brain-gut connection that impairs immune defenses during psychological stress
Recent research published in the journal Cell has found a link between our mental state and the immune system, particularly through an interaction between the brain and the gut. The study focused on a little-known structure in the digestive system called Brunner’s glands, located in the duodenum (the first section of the small intestine). These glands appear to play a pivotal role in how stress affects gut bacteria and immune defenses.
