Histamine release

Histamine release

The secretion of histamine from mast cell and basophil granules by exocytosis. This can be initiated by a number of factors, all of which involve binding of ige, cross-linked by antigen, to the mast cell or basophils fc receptors. Once released, histamine binds to a number of different target cell receptors and exerts a wide variety of effects.
