Question

Quizplus · Accepted Answer

Perforin is a protein produced by cytotoxic T cells and natural killer cells that is used to kill target cells, but it does not induce vasodilation or permeability. The other options - histamines, kinins, leukotrienes, and complement - are all involved in inducing vasodilation and permeability to promote inflammation and enhance immune response to infection.
