Protein that is produced by lymphocytes (white blood cells) and that attaches to a specific antigen. Antigen. Molecule on the surface of a pathogen that identifies it as a foreign invader to the immune system.Bacteria. Single-celled organism. Has a cell wall, cell membrane, cytoplasm.he white blood cells then produce antibodies to match the shape of the antigens. The antigens on the surface of pathogenic cells are different from those on the surface of your own cells. This enables your immune system to distinguish pathogens from cells that are part of your body.
The specialized cells of the immune system, called lymphocytes, are initially produced in the bone marrow. Lymphocytes mature either in the bone marrow to become B cells or in the thymus to become T cells. B cells produce antibodies that circulate in the blood or the lymphatic system. Antibodies attach to foreign antigens and mark these invaders for destruction by other cells in the immune system. T cells have two major roles. They can become cytotoxic T cells capable of destroying cells marked as foreign.
