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.
Although best known for their role in allergy and anaphylaxis, mast cells play an important protective role as well, being intimately involved in wound healing, angiogenesis, immune tolerance, defense against pathogens, and bloodâbrain barrier function.
