Explain antibody production.

Expert Answers

An illustration of the letter 'A' in a speech bubbles

"Antibodies are gamma globulin proteins that are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses."

When a macrophage (a type of white blood cell) consumes a bacteria or virus, proteins or antigens from the bacteria are then attached to the surface of the macrophage. When a T lymphocyte (type of white blood cell that attacks body cells that have been taken over by viruses or have become cancerous) recognizes the same protienon the macrophage and on the B lymphocte cell  (type of white blood cell that make antibodies that attack bacteria and toxins), the T cell stimulates the B cell to turn on antibody production.  The B cell then replicates itself to form antibody secreting cells. The antibodies attach themselves to the bacteria or virus making them easily destroyed by white blood cells.
