Quizplus · Accepted Answer

Type II hypersensitivity is antibody-mediated and occurs when antibodies bind to antigens on the surface of cells, leading to cell damage. In the case of an Rh-negative mother carrying an Rh-positive fetus, the mother's immune system produces antibodies against the Rh-positive antigens on the fetal red blood cells. These antibodies can cross the placenta and attack the fetal red blood cells, leading to hemolytic anemia in the fetus. In the case of a patient with A blood given B blood by mistake, the patient's immune system produces antibodies against the B antigens on the transfused red blood cells, leading to hemolytic transfusion reaction.
