GlossaryAntibodies

specialized proteins that identify and neutralize foreign substances

Antibodies, also known as immunoglobulins (Ig), are specialized proteins produced by the immune system to identify and neutralize foreign substances like bacteria, viruses, and toxins. They work by specifically binding to antigens on the surface of these invaders, marking them for destruction by other immune cells.
