Type I hypersensitivity is mediated by which of the following immunoglobulins?
Correct Answer: Ig E
Description: Type I hypersensitivity reaction is IgE dependent. Cytotoxic IgE antibodies are fixed on the surface of tissue cells ( mast cells and basophils) in sensitized individuals. The antigen combines with the cell fixed antibody, leading to release of pharmacologically active substance that produces the clinical reaction.
