An antigen called an allergen causes the immune system to react in an excessively ferocious way to a perceived threat that would otherwise be harmless to the body. Allergies are the term for such reactions.
Technically speaking, an allergen is an antigen that, when exposed to atopic persons, can trigger an immunoglobulin E (IgE) response, resulting in a type-I hypersensitivity reaction.
The majority of Immunoglobulin E responses in humans are only activated in response to parasite infections. Some people, however, may react to a variety of widespread environmental antigens. Atopy is the name given to this inherited tendency. Non-parasitic antigens in atopic people cause erroneous IgE production, which results in type I hypersensitivity.
