Answer to Question 1
Cytotoxic T cells attack and destroy body cells infected with viruses or intracellular bacteria. They can also attach cancer cells. Delayed hypersensitivity cells respond to foreign antigens processed by macrophages or similar cells by accumulating at the site of the antigenic material, where they secrete a variety of lymphokines that attract macrophages, activate them, and stimulate them to secrete additional cytokines.
