An antibody, also known as an immunoglobulin, is a specialized protein produced by white blood cells called B cells. It is a critical component of the immune system and plays a vital role in defending the body against invading pathogens such as bacteria, viruses, and other harmful substances. Antibodies recognize and bind to specific molecules on the surface of these pathogens, marking them for destruction by other immune cells or neutralizing their harmful effects. They contribute to the body's ability to mount an immune response, provide immunity against future infections, and help maintain overall health and well-being.An antibody, also known as an immunoglobulin, is a specialized protein produced by white blood cells called B cells.
