Allergens and Immunology

Allergens are substances that trigger an immune response in certain individuals, causing allergies. Immunology is the study of the immune system, which defends the body against infections and harmful substances. In allergies, the immune system mistakenly identifies harmless things—like pollen, food, or pet dander—as threats and releases chemicals such as histamine, leading to symptoms like sneezing, itching, or swelling. Understanding allergens and immunology helps in diagnosing, managing, and developing treatments for allergic conditions, improving quality of life for those affected.
