A nursing student is studying the body's response to an allergen. Which of the follow immunoglobulins is released during an allergic response?
Explanation
• IgE binds to allergens and triggers histamine release from basophils
• IgG provides the majority of antibody-based immunity against pathogens
• IgD acts as a receptor for B cells to produce antimicrobial factors
• IgA prevents pathogen colonization in the muscosa, gut, and respiratory tract
• IgM eliminates pathogens during the early stages of humoral immunity, before there is sufficient IgG
