D)Type IV

Question

Quizplus · Accepted Answer

A)Type I, or immediate hypersensitivity, reactions are characterized by rapid development of symptoms after exposure to an antigen; an example is anaphylaxis. Type II, or cytotoxic hypersensitivity, reactions involve the rupture of cells targeted by the immune response that may affect a variety of organs and tissues; examples include transfusion reactions and Rh incompatibility. Type III, or immune-complex, reactions include inflammatory response in the targeted tissues that leads to tissue damage; examples include autoimmune disorders such as systemic lupus erythematosus (SLE)and rheumatoid arthritis (RA). Finally, type IV, or delayed-type hypersensitivity, reactions involve a major histocompatibility complex and are characterized by tissue damage at the site of antigen contact within 24-48 hours of exposure; an example is allergic contact dermatitis.
