88. Which of the following is false concerning IgE. A. Basophils and mast cells have receptors for Fc of IgE. B. IgE & all other (Ig) antibodies have 4 identical chains held together by disulfide bonds. C. After sensitization (production of antibody and binding to mast cell and basophils), subsequent exposure to the antigen causes cross-linking and release of vasoactive mediators responsible for immediate hypersensitivity (hay fever, asthma, bee sting). D. Eosinophilia and IgE is often associated with certain worm infections. E. Worms coated with IgE may then be attacked by ADCC, because eosinophils have receptors for Fc of IgE and will then release lytic enzymes.
