Mast cells and basophils produce the histamine, which antihistamines block. The cytoplasm of a mast cell is filled with granules containing histamine and heparin. Histamine, released after injury or infection, stimulates local inflamation. People often take antihistamines to reduce cold symptoms. Basophils, blood cells that enter damaged tissues and enhance the inflammation process, also contain granules of histamine and haparin.
Eusonophils and Basophils produce histamine.Also mast cells produce histamine.
There are many, many substances released when tissues are injured, but one of the interesting ones would be prostaglandins. Some other substances of interest that are released would be histamine, antibodies, clotting factors, and a host of others.
histamine is produced by basophils and by mast cells found in nearby connective tissues. It is found in virtually all animal body cells.[
Both Heparin and Histamine are released by basophils and mast cells. These cells are very similar, but mast cells are found on mucous membranes (connective tissue) and basophils are white blood cells that travel in the blood in the circulatory system.

Histamine.
E. histamine
Mast cells secrete histamine and heparin.
The parietal cell in the stomach secrets gastric acid, which is hydrochloric acid (HCl). The Secretion of HCl by the parietal cell is stimulated by receptors for acetylcholine (muscarinic), histamine, and gastrin. The enterochromaffin cells (ECL) also have gastrin receptors and muscarinic receptors. ECL cells release histamine which reacts with H2 receptors (histamine 2 receptors) on parietal cells. Somatostatin is released by delta cells and decreases histamine release by ECL cells.
