An aeroallergy is an allergy to an airborne allergen.
Airborne allergens can trigger an allergic response in the body, leading to symptoms like sneezing, coughing, and itchy eyes. The body's defense against this involves producing antibodies like IgE to target and neutralize the allergen. If these defense tactics fail, the body may activate an inflammatory response, causing more severe symptoms like wheezing and difficulty breathing, which may require medical intervention such as antihistamines or corticosteroids.
An aeroallergen is any form of airborne allergen, such as pollen.
These tests involve the administration of allergen to elicit an immune response. Provocation tests, most commonly done with airborne allergens, present the allergen directly through the route normally involved.
An allergy is the reaction that the body will have, where as an allergen is something that causes the allergy to occur.
Your body responds with antibodies
it can happen.............a body is a body
histamine
An allergen is something that the body does not recognize, and as a result produces antibodies to them. When this happens, an immune reaction takes place, giving you symptoms such as a runny nose, rash, etc.
allergen
Your body doesn't "attack allergies". When you are exposed to something that sets off your allergies, your body is attacking a protein that is called an "allergen". This allergen can be anything, from pollen or ragweed to dust mites or the scent of a perfume. When you are exposed to the allergen, your body's immune system reacts against it as if it were an invading bacteria, setting up an inflammatory response. This is why you get the itchy watery eyes, runny nose, sneezing, dry throat reaction - it's your body's immune reaction.
