This state-of-the-art reference provides timely and clinically and experimentally useful information on the major proteins of mast cell secretory granules that are released into the lung, skin, gut, eye, and other tissues under the influence of diverse stimuli-including cytokines, growth factors, neuropeptides, and allergen-bound immunoglobulin E. Demonstrates the important roles proteases play in the maintenance of tissue homeostasis as well as in the damaging events linked with allergy and other varieties of inflammation!
