Autoimmune means “immunity against the self.” You develop autoimmune disease when your immune system which defends your body against disease decides that your healthy cells are foreign. Then they start to attack the healthy cells.
Usually, when an invader enters your body, like a bacteria or cold virus, your immune system, tries to identify, kill and eliminate the intruders.
The autoimmune disease can affect one or many different types of the body tissue, depending on the kind. Abnormal organ growth or changes in the organ function may also be the result of autoimmune disease.
There are as many as 80 types of autoimmune diseases. Most of them have similar symptoms which make it hard to diagnose. There’s also a possibility that you can have more than one disease at the same time.
Autoimmune disease fluctuates between periods of remission and flare-ups. At present, there is no curative therapy for this disease. Treatment procedure includes relieving symptoms and preventing complications.
Acquired immune system. It develops as a person grows. The acquired immune system remembers invaders and fights them when they come back. Foreign invaders provoke your body, to activate immune cells against the invaders. Your cells start to produce proteins called antibodies. The antibodies attach themselves to the intruder attacks them and kills them.
Innate immune system. This primitive immune system activates white blood cells to destroy invaders, without using antibodies.
In the case of an autoimmune reaction, your antibodies and white blood cell start to target your body’s healthy tissue, signaling the body to attack them.
