Mast cells play a key role in the inflammatory process. When activated, a mast cell can either selectively release (piecemeal degranulation) or rapidly release (anaphylactic degranulation) mediators, or compounds that induce inflammation, from storage granules into the local microenvironment.
They play an important role in helping defend these tissues from disease. By releasing chemical alarms such as histamine, mast cells attract other key players of the immune defense system to areas of the body where they are needed. Mast cells seem to have other roles as well.
