This document summarizes the process of mast cell activation. When an antigen binds to IgE antibodies on the surface of a mast cell, it activates anaphylatoxin receptors. This leads to the release of various inflammatory mediators including vasoactive amines, enzymes, leukotrienes, prostaglandins, and cytokines. These mediators cause smooth muscle contraction, increased vascular permeability, chemotaxis of eosinophils, platelet activation, and protease effects. Ultimately, this results in physiological effects associated with anaphylaxis.
