Type II cytotoxic hypersensitivity - is typified by the transfusion reaction.
Type II cytotoxic hypersensitivity - may be related to the development of Rheumatic fever.
Type I anaphylatic hypesensititvity - is predicted by IgE attachement to mast cells
Type IV cellular hypersensitivity - develops in poison Ivy
Type II cytotoxic hypersensitivity - is a cell damaging or destroying reaction
Type III immune complex hypersensitivity - is typified by the Arthus phenomenon
Type IV cellular hypersensitivity - does not involve antibody formation.
Type I anaphylatic hypesensititvity - involve degranulation of sensitized cells.
Type III immune complex hypersensitivity - invovle IgG reaction with antigens that may cause serum sickness
Type I anaphylatic hypesensititvity - may lead to death in 10-15 minutes from asphyxation

Match each description or example with the correct type of hypersensitivity. Type I (acute) hypersensitivity Type II (cytotoxic) hypersensitivity Type III (immune complex) hypersensitivity Type IV (delayed) hypersensitivity Answer Bank Antigens bind to IgE on basophils and mast cells and stimulate them to secrete vasoactive substances. IgG or IgM binds to an antigen, which leads to lysis or opsonization of target cell. T cells elicit a response 12-72 hours after initial exposure. Anaphylactic shock is an example of this type...

Please select the characteristics or components of Type 2 hypersensitivity reactions. Check All That Apply Complement is involved in lysis of cells. IgG and/or IgM is involved. Type 2 reactions may occur if mismatched blood given as a transfusion. Type 2 reactions involve basophils, mast cells, and histamine. Cytotoxic T cells play an important role in cytolysis in Type 2 reactions,
