Immune system disorders cause abnormally low activity or over activity of the immune system. In cases of immune system over activity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections.

Autoimmunity is present in all individuals; however, autoimmune disease occurs only in those individuals in whom the breakdown of one or more of the basic mechanisms regulating immune tolerance results in self-reactivity that can cause tissue damage.

Parkinson's disease (PD) is actually an autoimmune disease. Autoimmunity occurs when immune homeostasis is broken by several main mechanisms shown in this figure, which directly result in an increase in error recognition and self-attack and a decrease ...

Autoimmune Addison disease affects the function of the adrenal glands, which are small hormone-producing glands located on top of each kidney. It is classified as an autoimmune disorder because it results from a malfunctioning immune system that attacks the adrenal glands.

Rheumatoid vasculitis can affect blood vessels in many parts of your body. For this reason, it can cause many different symptoms. It most often damages blood vessels to the skin, fingers and toes, nerves, eyes, and heart. This reduces blood flow to these areas and damages them.

An autoimmune disorder causes your immune system – which usually fights off infections – to attack otherwise helpful parts of your body. In the case of Hashimoto's thyroiditis, your immune system attacks your thyroid, which can cause inflammation and lead to an underactive thyroid gland.

More than 80 different autoimmune diseases exist. Often their symptoms overlap, making them hard to diagnose. Autoimmune diseases are more common in women, and they often run in families. Blood tests that look for autoantibodies can help doctors diagnose these conditions.

An autoimmune disease is a condition in which your immune system mistakenly attacks your body. The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them.

On a basic level, autoimmune disease occurs because the body's natural defenses — the immune system — attack the body's own healthy tissue. 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.

Autoimmune brain diseases occur when the body's immune system attacks healthy cells and tissues in the brain or spinal cord, which results in inflammation. This inflammation may then cause impaired functioning, resulting in neurological or psychiatric symptoms.

In an autoimmune response, tissue destruction occurs. With allergies, the immune system overreacts to harmless allergens. Interestingly, this is the same type of response that expels viruses, parasites, and bacteria from the body.”
