As the liver repairs itself, fibrous tissue develops, much like a scar forms after a cut or injury to the skin heals. Advanced scarring of the liver is called cirrhosis. Over time, cirrhosis irreversibly damages the liver, eventually ending in liver failure. The immune system consists of different types of white blood cells that help to fight infections. Some of these cells produce antibodies.
Antibodies act as warriors.
They defend the body by destroying bacteria, viruses and other foreign materials. There are different kinds of antibodies, each fighting against a specific foreign substance. Thus, the immune system protects the body against outside invasion by germs. But sometimes, the immune system mistakenly recognizes the body's own organs as foreign. It can develop antibodies against these organs.
