What Cells Release Histamine

Question

What cells release histamine?
A)​mast cells
B)goblet cells
C)eosinophils
D)macrophages
E)​monocytes

Accepted Answer

Mast cells are the primary cells that release histamine in response to allergens, injury, or infection. Histamine is a chemical mediator of inflammation that causes vasodilation, increased permeability, and smooth muscle contraction. Goblet cells secrete mucus, eosinophils are involved in allergic reactions and immune responses, macrophages are involved in phagocytosis and elimination of pathogens, and monocytes differentiate into macrophages upon entering tissues.
