An allergen such as mold spores or pollen enters the body through the mouth or nose or lands on the skin. Special white blood cells (T-cells) recognize the allergen as foreign and release chemicals in response. These chemicals travel through the blood and instruct another kind of white blood cell (B-cells) to produce IgE antibodies. Some of these antibodies attach to the outside of another special type of white blood cell called a mast cell. Mast cells are scattered throughout the skin and respiratory tract and their purpose is to help mediate the inflammatory response of the immune system. IgE antibodies can remain attached to mast cells for many years.
