The gut constitutes a prominent part of the immune system. Its commensal microflora plays an important role in defense and in tolerance to diet allergens. Disturbances in immune regulations may lead to food allergy. Among commensal bacteria, bifidobacteria are able to induce mechanisms of immune tolerance. Comprehension of their mutual cross-talk with the host is necessary for understanding their role in the diet and in food supplements.
