Question

Quizplus · Accepted Answer

Killer T cells, also known as cytotoxic T cells, are lymphocytes that can recognize and destroy cells that have been infected by foreign organisms. They do so by releasing toxic substances that kill the infected cell. Helper T cells assist in the immune response by releasing chemicals called cytokines that stimulate other immune cells, but they do not directly kill infected cells. Suppressor T cells can regulate the immune response by suppressing the activity of other immune cells, but they do not directly kill infected cells. Phagocytes are a type of white blood cell that can engulf and digest pathogens, but they are not lymphocytes and do not directly kill infected cells.
