Changes in the gut microbiota at weaning could prevent inflammatory diseases

At weaning, changes in the gut microbiota trigger an immune reaction that is important for preventing allergies and other inflammatory diseases later in life.

Antibiotics can alter the development of the skeleton by disrupting the gut microbiota and, consequently, affecting the immune system.

How vitamin A and gut microbiota regulate the intestinal immune system

The gut microbiota reduces the production of retinoic acid, a metabolite of vitamin A, to regulate immune activity and prevent pathogens.

Bifidobacterium bifidum promotes immune tolerance in the gut
