Autoimmune diseases result from a dysfunction of the immune system. The immune system protects you from disease and infection. Sometimes, though, the immune system can produce autoantibodies that attack healthy cells, tissues, and organs. This can lead to autoimmune disease. Autoimmune diseases can affect any part of the body.
Why is Guillain-Barré syndrome called an autoimmune disease?
It is thought that, at least in some cases, this immune attack is initiated to fight an infection and that some chemicals on infecting bacteria and viruses resemble those on nerve cells, which, in turn, also become targets of attack. Since the body’s own immune system does the damage, GBS is called an autoimmune disease (“auto” meaning “self”).
Why do viruses attack the human body?
Researchers have several ideas about why this happens. When the body senses danger from a virus or infection, the immune system kicks into gear and attacks it. This is called an immune response.
How many people are affected by autoimmune diseases?
Collectively, these diseases affect more than 24 million people in the United States. An additional eight million people have auto-antibodies, blood molecules that indicate a person’s chance of developing autoimmune disease. Autoimmune diseases are affecting more people for reasons unknown. Likewise, the causes of these diseases remain a mystery.
What is autoimmune skin disease in dogs?
Autoimmune skin disease in dogs are a group of diseases that occur in dogs that are caused by the body’s immune system, where the body’s white blood cells or body’s antibodies attack its own tissues or extracellular protein of the skin. The immune system has the ability to differentiate between the body’s own cells and foreign cells.
How does the environment affect autoimmune diseases?
Studies indicate these diseases likely result from interactions between genetic and environmental factors. Gender, race, and ethnicity characteristics are linked to a likelihood of developing an autoimmune disease. 2 Autoimmune diseases are more common when people are in contact with certain environmental exposures, as described below.
What happens when an autoimmune disease flares up?
Symptoms of autoimmune disorders can come and go. When symptoms get worse, it is called a flare-up. Complications depend on the disease. Medicines used to suppress the immune system can cause severe side effects, such as higher risk of infections.
