Autoimmune diseases arise from an overactive immune response of the body against substances and tissues normally present. In other words, the body attacks its own cells. This may be restricted to certain organs or involve a particular tissue in different places.
In both autoimmune and inflammatory diseases the condition arises through aberrant reactions of the human adaptive or innate immune system. In autoimmunity, the patient’s immune system is activated against the body's own structures. In inflammatory diseases, it is the overreaction of the immune system, and its subsequent downstream signaling, which causes problems.
A substantial number of the population suffers from these diseases, which are often chronic, debilitating, and life-threatening. There are more than eighty illnesses caused by autoimmunity.
It has been estimated that autoimmune diseases are among the ten leading causes of death among women in all age groups up to 65 years.
