About Allergy An allergy is the response of the body's immune system to normally harmless substances, such as pollens, foods, and house dust mite. Whilst in most people these substances (allergens) pose no problem, in allergic individuals their immune system identifies them as a’ threat’ and produces an inappropriate response.

- An allergy occurs when the body reacts to substances it can't tolerate. The substances, like tree pollen or dust mites, are called environmental antigens, or allergens, and are normally harmless. But the immune system of a person with allergies views the allergens as harmful.ntibodies attach to the antigen and form an immune complex (antibody-antigen complex). The antibody and antigen fit tightly together, like pieces of a jigsaw puzzle. Sometimes an antibody can attach to other antigens if the antigens closely resemble the antigen that the antibody was formed to recognize and attach to.

Asthma and Allergies A. Asthma and allergies often go hand-in-hand. Asthma is a disease of the branches of the windpipe (bronchial tubes), which carry air in and out of the lungs. There are several different types of asthma. Allergic asthma is a type of asthma that is triggered by an allergy (for example, pollen or mold spores). According to the American Academy of Allergy, Asthma and Immunology, half of the 20 million Americans with asthma have allergic asthma.

- The substances that cause allergic disease in people are known as allergens. “Antigens,” or protein particles like pollen, food or dander enter our bodies through a variety of ways. If the antigen causes an allergic reaction, that particle is considered an “allergen” – and antigen that triggers an allergic reaction.

Allergen An allergen is a type of antigen that produces an abnormally vigorous immune response in which the immune system fights off a perceived threat that would otherwise be harmless to the body. Such reactions are called allergies.

This substance (pollen, mold, and animal dander, for example) is called an allergen. Allergies are a very common problem, affecting at least two out of every 10 Americans.
