The immune system is a complex and highly developed system, but its mission is simple: to seek and kill invaders. If a person is born with severely impaired immune system, death from infection by a virus, bacteria, fungi and parasites will be held. One of the key elements of the role of the immune system to distinguish between invaders and the body's own cells - when it can not make this distinction, a reaction against "self" cells and autoimmune disease causes the molecules. A. Immunodeficiency disease (primary or acquired)

2. Autoimmune disease (where the body's own immune system attacks its own tissue as foreign matter)

3. Allergic diseases (in which the immune system reacts in response to antigen)

4. Cancers of the immune system >> << In severe combined immunodeficiency, lack of the enzyme means that toxic waste builds up inside immune system cells, killing them and thus devastating the immune system. Lack of immune system cells as the basis for DiGeorge syndrome: development lasix drug for cats of the thymus wrong means that T cell production decreases.

Most other immune disorders resulting from or excessive immune response or "autoimmune attack. Asthma, familial Mediterranean fever and Crohn's disease (inflammatory bowel disease) all result in excessive immune response, while autoimmune polyglandular syndrome and some aspects of diabetes associated with the immune system attacks "self" cells and molecules. .
