Multiple Choice

Which is the best explanation of how immune suppression can be helpful in preventing transplant rejection?

• A) The immune system sometimes reacts against foreign antigens in the grafted tissue, causing what is often called a rejection syndrome. Immune suppression drugs reduce the immune system's ability to attack the foreign antigens in the donated tissue.
• B) Because rejection is caused by an inappropriate and excessive response to self-antigens, giving immune suppression drugs would reduce this effect.
• C) Rejection involves antigen-antibody reactions, mainly IgE triggered by repeated exposure to an allergen, so immune suppression drugs would reduce the reaction to the allergen, which in this case is the transplanted organ.
• D) Delayed allergic response occurs with transplanted organs, so immune suppressive drugs would reduce the allergic response and decrease rejection.
