Question

Quizplus · Accepted Answer

Tumor necrosis factor alpha is a chemokine that attracts neutrophils to the site of an infection. Histamine is not a chemokine, it is involved in the inflammatory response and can cause vasodilation and increased vascular permeability. Proteases break down proteins and are not directly involved in attracting neutrophils. Prostaglandins are hormone-like molecules that can cause inflammation and pain but are not chemokines.
