Work
Our immune system protects us from attacks by microorganisms. As part of its defenses, the immune system forms antibodies in the blood that neutralize poisons, or toxins, that are formed by bacteria. One of Paul Ehrlich’s contributions to immunology was the transfer of blood serum with antibodies to treat and counteract diphtheria, which he carried out with Emil von Behring. Ehrlich speculated that cells have a kind of receptor that binds to the harmful substances. The receiving elements are knocked off of the cell and become antibodies.
