Mast Cells in Activation

This intricate design is an interpretation of mast cells in activation. In this image, the mast cell, similar in appearance to a white blood cell (white/blue areas), contains many storage granules (purple spheres) rich in histamine and heparin (small orange granules). When allergens (green & pink spiked shapes) make contact with antibodies (yellow Y-shaped pairs), a mast cell reaction is triggered, releasing histamine into the system (represented by the release of orange granules). Learn more about mast cells.
