Summary
The mast cell, a potent inflammatory cell type, is widely distributed over several
tissues, but particularly prominent at the interface exposed to the environment to
act in the first line of defense against pathogens. Upon activation mast cells release
granules, which contain a large panel of mediators, including neutral proteases (e.g.
chymase and tryptase), cathepsins, heparin, histamine and a variety of cytokines and
growth factors. While mast cells have been demonstrated to be critically involved
in a number of Th2 dominated diseases such as asthma and allergy, recent investigations
have now also implicated mast cells in the pathogenesis of atherosclerosis and acute
cardiovascular syndromes. In this review, we will discuss the contribution of mast
cells to the initiation and progression of atherosclerosis and gauge the therapeutic
opportunities of mast cell targeted intervention in acute cardiovascular syndromes.
