Quizplus · Accepted Answer

Delayed hypersensitivity occurs independent of antibodies and is mediated by T cells. The other types of hypersensitivity involve antibodies in some way. Immune-complex hypersensitivity involves the formation of immune complexes, which can activate complement and cause damage. Immediate hypersensitivity involves IgE antibodies bound to mast cells and basophils, leading to immediate allergic reactions. Cytotoxic hypersensitivity involves antibodies that directly target and kill cells.
