One of the best-known chemical mediators released from cells during inflammation is histamine, which triggers vasodilation and increases vascular permeability. Stored in granules of circulating basophils and mast cells, histamine is released immediately when these cells are injured.
Normally, the first responders to the site of injury or infection are white blood cellsâincluding macrophages. They produce waves of chemicals, including cytokines, which can kill germs and sound the alarm for other populations of inflammatory cells. But fat cells can produce cytokines, too.
