Some Basics About Immunity
The immune system is comprised of highly specialized white blood cells.  NK cells are a major component of the body's first line of defense that engulf and destroy foreign invaders.  B-cells make antibodies that tag foreign invaders.  T-cells identify and attach targeted invaders.  In addition, Interferon enhances the communication and activity of B-cells and T-cells.*
