Question

Quizplus · Accepted Answer

Allergic reactions are triggered by the production of IgE antibodies instead of IgG antibodies at the first exposure to the allergen. IgE antibodies are produced by B cells in response to allergens such as pollen, dust mites, and certain foods. On subsequent exposure to the allergen, the IgE antibodies bind to mast cells and basophils in various tissues, leading to the release of inflammatory mediators such as histamine, which produce the symptoms of an allergic reaction.
