Antikorlar, or antibodies, are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses. They play a crucial role in the body's defense mechanism, recognizing specific antigens, which are unique molecules found on the surface of pathogens. When the body encounters an antigen, it triggers the production of antikorlar that bind to the antigen, marking it for destruction by other immune cells. This process helps prevent infections and diseases, making antikorlar essential for maintaining health and supporting the immune response against various pathogens, including viruses and bacteria.
