As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues.on-mast cell histamine is found in several tissues, including the brain, where it functions as a neurotransmitter. Another important site of histamine storage and release is the enterochromaffin-like (ECL) cell of the stomach.
Histamine is the primary effector substance released by the mast cell in response to an allergen. Antihistamines block H1 (histamine, type 1) receptors found on blood vessel endothelial cells and smooth muscle cells.he use of antihistamines to treat hayfever will also help to relieve asthma and reduce the severity of its symptoms. Antihistamines are available in tablet, nasal spray, cream, and eye drop form. The eye drops are useful for the red and itchy eyes often caused by airborne allergens like pollen.
