Question

Quizplus · Accepted Answer

Cytotoxic T cells specialize in cell-to-cell combat.They have storage vacuoles containing perforins and storage vacuoles containing enzymes called granzymes.After a cytotoxic T cell binds to a virus-infected cell or cancer cell,it releases perforin molecules,which perforate the plasma membrane,forming a pore.Cytotoxic T cells then deliver granzymes into the pore,and these cause the cell to undergo osmotic destruction and die.
