Which molecule from a cytotoxic T cell creates holes in plasma membranes of virus-infected or cancer cells?
A)cytokine
B)interleukin
C)perforin
D)interferon

Question

Quizplus · Accepted Answer

Perforin is a protein found in the granules of cytotoxic T cells and natural killer cells. When activated, it forms pores in the plasma membrane of virus-infected or cancer cells, leading to lysis or death of the target cell. Cytokines (A) and interleukins (B) are signaling molecules released by immune cells to coordinate the immune response, but they do not directly cause membrane damage. Interferons (D) are proteins that interfere with viral replication and activate immune cells, but they do not produce pores in cell membranes.
