The Allergens at a Closer Look

Generally, allergens are everywhere. They take the forms of dust mites, pollens, grasses, foods, pet dander, to name a few. The allergens are known to be the special kinds of antigens which prompt the allergic reactions of the body. The body is technically protected by the immune system. Now if it recognizes some foreign invaders, a part of the immune system gets turned on and then starts to generate the antibodies to combat the foreign substances. This results to the allergic reactions.

The diseases and their symptoms actually depend on the route and level of entry and exposure of the body's susceptibility to the allergens. The allergens are comprised of various chemicals so the reaction is largely dependent on the part of the body that has been exposed. Simply put, the airborne pollens will produce a little effect when it gets in contact with the skin but it will be entirely different if the food allergens get ingested. In short, the allergens may be ingested as in the case of food allergens, inhaled as in the case of airborne pollens and animal dander, applied onto the skin, or injected into the body as in the case of an insect sting.
