WebThe kinins are also important inflammatory mediators. The most important kinin is bradykinin, which increases vascular permeability and vasodilation and, importantly, activates phospholipase A 2 (PLA 2) to liberate arachidonic acid (AA). Bradykinin is also a major mediator involved in the pain response. WebOne 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.
