The Roles of Antibodies 1- Neutralization •prevents antigen (e.g., virus, toxin) from functioning

4. 2) Opsonization •enhancing the process of phagocytosis Phagocytes such as macrophages have receptors for the constant region (FC) of antibodies: •FC receptors allow phagocytes to “grab onto” antigen-antibody complexes much more easily makes it much easier to engulf and destroy pathogens by phagocytosis
