Metabolism of LDL in mast cells recovering from degranulation. Description of a novel intracellular pathway leading to proteolytic modification of the lipoprotein

Mast cells: function and contents

Mast cells, when activated, release a spectrum of mediators that initiate and modulate immediate-type hypersensitivity reactions. Recently is has been reported that expression of mast cell neutral proteases, specific markers of mast cells, is regulated by various growth factors. Human mast cells, like those in rodents, are now known to produce cytokines that modulate IgE production and inflammation.
