Detailed explanation-1: -Allergic reactions are the result of the production of specific IgE antibody to common, innocuous antigens. Allergens are small antigens that commonly provoke an IgE antibody response. Such antigens normally enter the body at very low doses by diffusion across mucosal surfaces and therefore trigger a TH2 response.
Detailed explanation-2: -What are IgE-mediated food allergies? IgE-mediated food allergies cause your child’s immune system to react abnormally when exposed to one or more specific foods such as milk, egg, wheat or nuts. Children with this type of food allergy will react quickly-within a few minutes to a few hours.
Detailed explanation-3: -antigen, substance that is capable of stimulating an immune response, specifically activating lymphocytes, which are the body’s infection-fighting white blood cells.
