    GlossaryImmunoglobulin E

    antibody involved in allergic reactions and parasite defense

    Immunoglobulin E (IgE) is a type of antibody produced by the immune system. It plays a crucial role in allergic reactions by binding to allergens and triggering the release of histamine and other chemicals from mast cells and basophils, leading to symptoms like itching, swelling, and redness. Elevated levels of IgE are often associated with conditions such as asthma, hay fever, and eczema.
