When the same allergen is encountered again, it binds directly to the IgE antibody stuck to the outside of mast cells. This causes the mast cells to release chemicals such as histamine. Histamine is an example of a chemical mediator - a special messenger chemical that immune cells use to talk to each other.

Raw latex is mixed with a variety of different chemicals that allow the latex to polymerize, or form, into long chains that can then be manipulated to form solid objects. Some of these chemicals can also cause allergic reactions that present as mild to severe itchy, red bumps or rashes (contact dermatitis). However, these chemicals do not cause asthma, hives, or hayfever-type symptoms.
