13. Match the following types of hypersensitivities to the appropriate statements. Types may be used more than once. (5 pts) A. Hypersensitivity type II B. Hypersensitivity type III C. Hypersensitivity type IV __ Not mediated by antibodies but mediated by Th1 CD4 cells and CD8 cytotoxic T cells. Occurs mainly on second exposure to the allergen. __ Tissue damage occurs by the recruitment of immune and inflammatory cells such as neutrophils, and the activation of complement. This is seen mostly in Rheumatoid Arthritis and SLE. __ Inflammatory response is seen as a fluid buildup, accumulation of macrophages and localized tissue damage. Contact dermatitis is an example. __ Immune complexes are formed when soluble antigens and antibodies form large structures or lattices that can precipitate out of solution and get stuck at various anatomical filtering sites. __ Involves complement-activating antibodies IgG and IgM and antibody and complement mediated lysis, opsonization and antibody-directed cellular cytotoxicity.
