Type II hypersensitivity reactions are caused by antibodies directed against body tissues that have some form of non-self (foreign) protein attached to them. These antibodies not only attack the non-self protein but also damage the normal cells associated with the non-self protein. Common clinical situations caused by type II hypersensitivities include hemolytic anemias, he-molytic transfusion reactions, and Goodpasture's syndrome.
