IMMUNE FOR LIFE INFORMATION FILE: IMMUNITY FROM WHAT?
What threatens your immunity? What is it your immune system protects you from? Antigens. Antigens are viruses, bacteria, cancer cells, fungi, protozoa (microscopic animals), particles, and anything else that challenges your immune system.
Antigens are the reason the immune system exists. If there were no antigens, to worry about, there would be no need for an immune system.
Not every antigen will excite the immune system into action. Some cancers for example, may disguise themselves in such a way that they remain in the body, undetected by the immune system, until it’s too late.
Of course, antigens don’t take being attacked lying down. They have their own weapons, strategies and tricks. Some antigens try to fool the immune system by changing their surface configuration, so they won’t be recognized. Others battle the immune system, hoping to overwhelm it. As the microscopic battle rages, millions of our immune soldiers die. The AIDS virus seems particularly adept at crippling the immune system’s ability to mount a defense.
