Immunoglobulin E response

Immunoglobulin E (IgE) is a type of antibody produced by the immune system in response to allergens, such as pollen, pet dander, or certain foods. When the body encounters these substances, IgE binds to them, triggering allergic reactions. This can lead to symptoms like sneezing, itching, or more severe responses like anaphylaxis. IgE plays a key role in defending against parasites but is often responsible for allergies. Understanding IgE helps in treating allergic reactions and managing conditions like asthma or hay fever.
