Quizplus · Accepted Answer

IgE antibodies are involved in causing immediate allergic reactions, also known as type I hypersensitivity reactions. When an allergen enters the body and binds to IgE antibodies on mast cells and basophils, it triggers the release of inflammatory mediators such as histamine, which leads to symptoms such as swelling, itching, and hives. IgA antibodies are mainly found in mucosal secretions and play a role in defending against pathogens in these areas. IgD antibodies are found on the surface of B cells and their exact function is not fully understood. IgG antibodies are the most abundant type of antibody in circulation and are involved in long-term immunity against pathogens.
