WebAntibodies are produced by B cells (specialized white blood cells ). When an antigen comes into contact with a B cell, it causes the B cell to divide and clone. These cloned B cells — or plasma cells — release millions of antibodies into your bloodstream and lymph system. WebWhen infectious agents, such as bacteria, enter the body, pieces of their machinery can be visible on the surface of their cells. These pieces are called antigens, and B cells activate when they encounter and recognize antigens. B cells have B cell receptors (BCRs) on their surface, and these BCRs bind to specific antigens. st philip\u0027s college class
