What are immunogens that cause hypersentivities called?
Allergens
Immunogens that cause hypersensitivities are called allergens. Allergens are substances that trigger an inappropriate immune response in certain individuals, leading to the development of allergies or hypersensitivity reactions. Common allergens include pollen, dust mites, animal dander, certain foods, and medications. When a person is exposed to an allergen, their immune system produces immunoglobulin E (IgE) antibodies that bind to and activate mast cells and basophils, resulting in the release of histamine and other inflammatory mediators. This can lead to symptoms such as itching, swelling, wheezing, and other allergic reactions. Allergens can be identified through allergy testing, which may involve skin tests or blood tests. Treatment for allergies may include avoidance of the allergen, medications to manage symptoms, and in some cases, allergy shots (immunotherapy) to desensitize the immune system to the allergen.
