An allergy is a hypersensitivity disorder of the immune system. Allergic reactions occur when a person’s immune system reacts to normally harmless substances in the environment. A substance that causes a reaction is called an allergen. These reactions are acquired, predictable, and rapid. Allergy is one of four forms of hypersensitivity and is formally called type I (or immediate) hypersensitivity. Allergic reactions are distinctive because of excessive activation of certain white blood cells called mast cells and basophils by a type of antibody called Immunoglobulin E (IgE). This reaction results in an inflammatory response which can range from uncomfortable to dangerous.

IgE and Asthma

Immunoglobulin E (IgE) is a type of antibody that is present in minute amounts in the body but plays a major role in allergic diseases. IgE binds to allergens and triggers the release of substances from mast cells that can cause inflammation. When IgE binds to mast cells, a cascade of allergic reaction can begin.

  • Allergen exposure: Repeated exposure to a particular allergen can be the first step in developing a reaction to it. Some allergens trigger strong allergic reactions, while others trigger milder reactions.
  • T cell action: Allergens induce T cells to activate B cells, which develop into plasma cells that produce and release more antibodies.
