Illustration of antibody, or immunoglobulin, molecules attacking bacteria (white). The y-shaped antibody molecules have two arms that can bind to specific antigens, for instance bacterial proteins. In doing this they mark the antigen for destruction by phagocytes, white blood cells that ingest and destroy foreign bodies. Antibodies can also kill some pathogens directly and can neutralise toxins. | |
