Illustration of antibody molecules (orange) biding to antigen molecules (blue). Antibodies, or immunoglobulins, are proteins produced by plasma cells (white blood cells) and used by the immune system to defend against foreign objects such as bacteria and viruses. They recognise specific antigens, for instance viral proteins, marking them for destruction by other immune cells. | |
