Non-IgG antibodies, such as IgM, IgA, and IgE, play distinct roles in the immune system.

IgM: The first antibody produced in response to an infection, effective in forming complexes and activating complement. IgA: Found mainly in mucosal areas (like the gut and respiratory tract), it protects mucosal surfaces by neutralizing pathogens and preventing their adherence. IgE: Involved in allergic reactions and responses to parasitic infections, it binds to allergens and triggers histamine release from mast cells. These antibodies contribute to a diverse immune response, offering specialized functions tailored to different types of threats.
