GALT interacts strictly with gastrointestinal functions in a dynamic manner; for instance, by increasing intestinal permeability in replay to particular stimulations, or orientating the immune response towards luminal content, allowing either tolerance or elimination / degradation of luminal antigens, or sometimes provoking damage to the intestinal mucosa, such as in coeliac disease or food allergy.

For instance, a decrease in bifidobacteria populations leads to intestinal hyper - permeability, or leaky gut, which in turn leads to the translocation of metabolic byproducts, food antigens, bacteria, and lipopolysaccharide (also known as LPS, an immunogenic cell wall component from Gram - negative bacteria) across the gut barrier into systemic circulation (Rapin & Wiernsperger, 2010).
