Question

Quizplus · Accepted Answer

IgE molecules are found on the surface of mast cells and basophils, which are involved in the immune response to allergens. When an allergen binds to the IgE molecule on a sensitized mast cell, it triggers degranulation (release of histamine and other inflammatory mediators), leading to allergy symptoms such as itching, swelling, and inflammation. IgG, IgB, and IgM are not typically involved in allergic reactions.
