What Causes it?
The “Immune Response” happens when your body detects any signs of attackers’ presence. In most cases, the attackers are disease-causing pathogens. When your white blood cells discover an antigen that has fallen off an attacker, they treat the antigen evidence that the whole body may be under attack and begin preparing themselves for battle.

⇒Topic: Immune Response: What Causes It?
White Blood Cells
The white blood cells are tiny blood cells that protect your body against foreign invaders.
Antigens are molecules that cover the surface of a pathogen or other foreign substances. These molecules fall off from time to time. When these molecules are discovered by white blood cells, the white blood cells often treat them as evidence that the body is under attack by pathogens or foreign objects.
