In autoimmune diseases such as MS and CD, the immune system mistakenly targets the cells, tissues and organs of a persons body, generally causing inflammation. Inflammation is a response of body tissues to trauma, infection, chemical or physical injury, allergic reaction or other factors. It is usually characterized by a collection of cells and molecules at a target site. Different autoimmune diseases affect the body in different ways. For example, in MS, the autoimmune reaction is directed against the brain, and in Crohns disease, it is directed against the gastrointestinal tract. Autoimmune diseases are often chronic, affecting millions of people and requiring life-long care. Most autoimmune diseases cannot currently be reversed or cured.
