[Contribution of indicators of sensitized T lymphocytes in the diagnosis of IgE independent and IgE dependent cow's allergy in children].

Background: Food allergy is an abnormal response of the immunological system, especially of mucosal immunological system on antigens supplied per os. There are very complicated and still unexplained immunological mechanisms, which lead to hypersensitivity reaction. Most often food hypersensitivity is identified as the effect of atopy, which is connected with humoral response (specific IgE antibody).
