Verified step by step guidance
1
Understand the role of antibodies in the immune response. Antibodies, also known as immunoglobulins, are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.
Learn about the different classes of antibodies: IgG, IgA, IgM, IgD, and IgE. Each class has a specific role in the immune response.
Focus on IgE antibodies. IgE is primarily associated with allergic reactions. When an allergen is encountered, IgE binds to it and triggers immune cells, such as basophils and mast cells, to release histamine and other chemicals.
Understand the function of basophils. Basophils are a type of white blood cell that plays a role in inflammatory reactions, particularly those related to allergies. They release histamine when activated by IgE antibodies.
Conclude that IgE is the antibody involved in causing basophils to release histamine when it encounters an allergen, leading to allergic symptoms.
