The immune system then attacks that cell. Some white blood cells (B cells) recognize invaders, or antigens, directly. When a B cell recognizes and attaches to the antigen, it produces antibodies, which coat the surface of the virus or bacteria to stop it from multiplying or infecting other cells.This process is called neutralization.ther white blood cells (T cells) need help from cells that first ingest the invader and break it into fragments. The fragments are then presented to the T cells so that they can recognize and destroy them. These helper cells are called antigen presenting cells.
