The Conversation – Paxton Loke
Researchers don’t know exactly why some children grow out of their food allergies. But their immune response to food allergens seems to change. For instance, these children have lower levels of antibodies you’d normally see as part of an allergic response (lower levels of allergen-specific IgE). They also have higher levels of other immune system components (allergen-specific IgG4, IL-10 and allergen-specific T cells). Other research has focused on a type of T cell, called the regulatory T cell, which regulates how the adaptive immune system responds to antigens.
