Detailed explanation-1: -A food allergy is an immunoglobulin E (IgE)-mediated hypersensitive reaction to food, which consists in the appearance of allergic symptoms; it can vary from common urticaria to even fatal anaphylaxis.
Detailed explanation-2: -Immunoglobulin E (IgE) – A rapid immune response that can be triggered by food. Immunoglobulin G (IgG) – A more delayed and potentially more mild immune response that can be triggered by food. Immunoglobulin A (IgA) – An antibody that can support the immune functions of mucous membranes.
Detailed explanation-3: -Immunoglobulin E (IgE) antibodies are well known for their role in mediating allergic reactions, and their powerful effector functions activated through binding to Fc receptors FcRI and FcRII/CD23.
