Question

Quizplus · Accepted Answer

IgE is associated with allergic reactions. When an allergen enters the body, it triggers an immune response that involves IgE antibodies. These antibodies bind to mast cells and basophils, causing the release of histamine and other chemicals that lead to the symptoms of an allergic reaction. IgA is primarily found in mucosal areas and is involved in defense against pathogens. IgD is found on the surface of B cells and plays a role in initiating the immune response. IgM is the first antibody produced in response to an infection.
