Question 1
Tissue damage caused by the deposition of circulating immune complexes containing an antibody against the host DNA is the cause of which disease?
◦ Hemolytic anemia
◦ Pernicious anemia
◦ Systemic lupus erythematosus
◦ Myasthenia gravis
Question 2
A patient asks the healthcare professional why tissue damage occurs in acute rejection after organ transplantation. What response by the professional is best?
◦ Th1 cells release cytokines that activate infiltrating macrophages, and cytotoxic T cells directly attack the endothelial cells of the transplanted tissue.
◦ Circulating immune complexes are deposited in the endothelial cells of transplanted tissue, where the complement cascade lyses tissue.
◦ Receptors on natural killer cells recognize antigens on the cell surface of transplanted tissue, which releases lysosomal enzymes that destroy tissue.
◦ Antibodies coat the surface of transplanted tissue to which mast cells bind and liberate preformed chemical mediators that destroy tissue.
