Question

Quizplus · Accepted Answer

Killer T cells are specialized lymphocytes that can identify and eliminate infected or cancerous cells. They do this by producing chemicals that cause the target cells to break down and die. Helper T cells activate other cells of the immune system, but do not directly kill infected or cancerous cells. Suppressor T cells help regulate the immune response and prevent excessive inflammation, but do not directly kill infected or cancerous cells. Phagocytes are another type of immune cell that can engulf and destroy foreign organisms, but they are not specific to infected or cancerous cells.
