Compare and contrast the difference between helper T cells and cytotoxic T cells
What will be an ideal response?
Answer: Helper T cells become activated by an antigen that was engulfed and digested by a phagocyte and presented to the helper T cell. The helper T cell clones stimulate antibody production by plasma cells, increase phagocytosis, and stimulate cytotoxic T cells and natural killer cells. Cytotoxic T cells (also called CD8 cells) are activated by antigens displayed in infected cells, abnormal cells, and transplanted organs and tissue. In response to these antigens, an activated cytotoxic T cell kills infected and abnormal cells and also kills transplanted organs and tissues.
