How Breastfeeding Promotes Food Tolerance (IMAGE) Boston Children's Hospital Caption As this schematic shows, mothers exposed to food allergens transfer antibodies to their offspring via breastmilk. Their immune systems make a complex of the antibody and allergen (IgG-IC complex), which is transferred to offspring through cells in the intestine, with the help of a receptor called FcRn. Dendritic cells, a type of immune cell, then process the Ig-IC complex and present it on their surface. This stimulates production of allergen-specific T regulatory (Treg) cells that interact with other immune cells to suppress food allergy.
