Question

Quizplus · Accepted Answer

After binding to an infected cell, the cytotoxic T cell releases a protein called perforin, which forms pores in the cell membrane of the infected cell, causing it to rupture and die. This allows the cytotoxic T cell to neutralize the infecting bacteria or viruses. Interleukin-1 is released by helper T cells to stimulate the immune response, and cytotoxic T cells are not phagocytic cells.
