Question

Quizplus · Accepted Answer

A severe allergic reaction to a bee sting is caused by the release of histamine and other chemicals by mast cells and basophils, which are triggered by an immune response involving IgE antibodies. Toxoids are inactivated toxins used for vaccination against infectious diseases. IgA is an antibody that plays a role in mucosal immunity. IgM is the first antibody produced in response to an infection. None of these are directly involved in an allergic reaction to a bee sting.
