Symptoms

When the allergen encounters the antibody it signals the cell to release powerful inflammatory chemicals like histamine, cytokines and leukotrienes. These chemicals act on tissues in various parts of the body, such as the respiratory system, and cause the symptoms of allergy.

Allergens that cause allergic reactions include pollens, dust particles, dust mites, mold and fungus spores, food or medicines. Millions of people in North America are allergic to "house dust". House dust is a mixture of potentially allergenic materials.
