What does gut biome have to do with type-1 diabetes? Three-week-old PAT males, for instance, had a nearly complete loss in their intestines of certain bacteria shown in past studies to normally train the immune system. The working theory is that bacteria in the gut is involved with training the immune system to not attack itself. I wonder if lack of gut biodiversity in infants could also be leading to increased incidence of other autoimmune disorders?
