Mast cells MCs are hematopoietic tissue immune cells that act both as effector and regulatory cells eg in adaptive and innate immunity eg This versatility is reflected in the myriad of immunologic and non-immune activation stimuli eg by G protein-coupled receptors resulting in the secretion of a large number 1000 of pre-stored. High levels of mast cell mediators are released during those episodes.
