A condition in which the body recognizes its own tissues as foreign and directs an immune response against them.

A disorder in which the immune system attacks the animal's own antigens.

Disease that occurs when the body's immune system accidentally recognizes a natural substance produced by the body as foreign, for unknown reasons, and attacks that substance. Some autoimmune diseases are insulin-dependent diabetes mellitus, lupus, thyroid disease, and vitiligo (loss of skin color).

Any disorder in which the body is attacked by its own immune system. Examples are goodpasture syndrome and lupus erythematosus.

a condition in which the body produces an immune response against its own components. This can lead to chronic inflammation or tissue destruction.

A disease where the body's immune system goes awry and attacks its own tissues.

a disease in which the immune system erroneously attacks self-cells

A disorder of the body's immune system in which the immune system mistakenly attacks itself. Examples of these diseases include type 1 diabetes, hyperthyroidism caused by Graves' disease, hypothyroidism caused by Hashimoto's disease.

A disease that occurs when the body's immune system mistakenly attacks the body itself.

Disease in which the body produces disordered immunological response against itself.

Disease caused by the production of antibodies (special proteins produced by immune cells in response to antigens) against self-proteins. These antibodies destroy important proteins of the body and cause disease, e.g., Grave's disease when antibodies specific for thyroid stimulating hormone receptors are formed.

Pathological condition resulting when an organism produces antibodies or specific cells which bind to constituents of its own tissues (autoantigens) and cause tissue injury: examples of such disease may include rheumatoid arthritis, myasthenia gravis, and scleroderma. RT allergy, antibody, antigen, hypersensitivity, immune response.

One of a number of otherwise unrelated disorders caused by inflammation and destruction of tissues by the body's own immune response. It is not known why the body should lose the ability to distinguish between substances that are ‘self' and those that are ‘non-self'

A disease in which the body produces an immunogenic (i.e., immune system) response to some constituent of its own tissue. In other words the immune system loses its ability to recognize some tissue or system within the body as "self" and targets and attacks it as if it were foreign. Autoimmune diseases can be classified into those in which predominantly one organ is affected (e.g., hemolytic anemia and anti-immune thyroiditis), and those in which the autoimmune disease process is diffused through many tissues (e.g., systemic lupus erythematosus). For example, multiple sclerosis is thought to be caused by T cells attacking the sheaths that surround the nerve fibers of the brain and spinal cord. This results in loss of coordination, weakness, and blurred vision.

Diseases resulting from the immune system mistaking tissues as “other” rather than “self,” including thyroiditis, lupus, myasthenia gravis, and generalized demodectic mange. Tendency toward these diseases is often inherited and can be exacerbated by inbreeding.

Diseases caused by an individual's immune system producing antibodies against tissues of its own body.

or disorder - A category of diseases and disorders in which one's own cells are mistakenly identified as "foreign" by the body and are therefore attacked by the immune system, causing tissue damage.

failure of the immune system to differentiate the body’s own cells from foreign substances, triggering an inflammatory response against self. This can be in the form of a very specific immune attack, such as the destruction of pancreatic islet cells resulting in diabetes mellitus, or a broad immunologic injury such as lupus.

disorder characterized by inflammation and tissue destruction caused by the immune system's inability to distinguish between 'self' and 'non-self' substances

a condition in which the body's own defense system reacts against some part of the body itself

a condition where a person's immune system destroys their own tissue

a disease where the body makes antibodies that attack normal parts of the body instead of the "foreign" molecules

a misdirected immune response

a pathological condition in which the immune response is directed to self antigen

A process in which the body's immune system causes illness by attacking elements, such as particular cells or materials, that are normal and essential for health. The immune system is the body's defense system against abnormal substances (such as viruses or bacteria) in the body. In autoimmune disorders, the body's defense system attacks substances that are needed by (versus harmful to) the body

A disease in which a part of the body's immune system attacks cells that make up part of the body, such as skin, connective or joint tissue, intestinal tissue, nerve cell messages, etc. Specific disease (over 80 diseases) include Rheumatoid Arthritis, Lupus (SLE), Inflammatory Bowel Disease, Eosinophilic Enteritis, Myasthenia Gravis, and others.

A disease produced when the body's normal tolerance of its own constituents disappears, resulting in the attack and destruction of the body's normal cells by the immune system

disease caused by an immune response against foreign substances in the tissues of one's own body.

is a disorder in which a person's own antibodies destroy body tissues, such as the beta cells in the pancreas.

A disease in which the immune system destroys or attacks a person's own tissues.

Relating to or caused by antiboides or T cells that attack molecules, cells, or tissues of the organism producing them.

A disease produced when the body's normal tolerance of its own antigenic markers on cells disappears. Autoantibodies (AAbs) are produced by B lymphocytes and attack normal cells whose surface contains a "self" antigen, or autoantigen(AAg), causing destruction of tissue. Diabetes mellitus, in which AAbs attack the insulin-producing cells of the pancreas, is an auto-immune disease. Others include rheumatoid arthritis, caused by inflammatory changes in the connective tissue of joints, and multiple sclerosis, caused by AAb destruction of the myelin sheath covering nerves. Hemolytic anemia, some forms of glomerulonehritis, myasthenia gravis, chronic thyroiditis, Reiter's syndrome, Graves' disease, and systemic lupus erythematosus are also considered autoimmune diseases. SEE: autoimmunity.

where the body actually attacks itself as if it were a foreign invader. Lupus, Rheumatoid Arthritis, Type I Diabetes, Hashimoto's Thyroiditis are examples.

a disease resulting from a disordered immune reaction in which antibodies are produced against one's own tissues. For example, lupus erythematosus.

A large group of diseases in which the immune system recognizes the body’s own tissues as foreign and attacks them.

A disease in which the immune system attacks elements of the patient's own body.

A disease caused by a break-down of self-tolerance such that the adaptive immune systems to self antigens and mediates cell and tissue damage. Autoimmune diseases can be organ specific (e.g. multiple sclerosis) or systemic (e.g. systemic lupus erythematous) (1).

Diseases characterized by an individual's immune system developing an inappropriate responses to their own cells or tissues.

Occurs when a specific adaptive immune response is mounted against the self. It is not known what triggers the autoimmune response, but susceptibility to most autoimmune diseases shows a significant genetic component. Environmental factors such as infection or diet are likely to play a role in pathogenesis.

Diseases caused by an individual's immune system producing antibodies to the persons own cells. These antibodies can be directed against red blood cells (autoimmune anemia), platelets (autoimmune thrombocytopenia) or other tissues. In some cases, the autoimmune disease is mediated by T lymphocytes that attack the tissues directly.

A disease in which the body’s own immune system attacks the individual’s own cells or tissues.

A process in which the body's immune system causes illness by mistakenly attacking healthy cells, organs, or tissues in the body. Multiple Sclerosis is believed by many to be an autoimmune disease, along with systematic lupus erythematosus, rheumatoid arthritis, and many others. The precise origin and pathophysiologic processes of these diseases are unknown.

A disease caused by the body's protective mechanism becoming confused and attacking a part of the body, which is not an invader.

A disease in which the immune system attacks and destroys the body's own tissues that it mistakenly believes to be foreign.

Disorders in which the body mounts a destructive immune response against its own tissues.

Disease in which the immune system mistakenly attacks the body's own cells and tissues; this immune reaction is the basis of a variety of e.g. diabetes, rheumatoid arthritis and system lupus erythematosus, among others.

a disorder in which a person's immune system attacks parts of his or her own body.

An illness that occurs when the body tissues are attacked by its own immune system . The immune system is a complex organization within the body that is designed normally to "seek and destroy" invaders of the body, including infectious agents. Patients with autoimmune diseases frequently have unusual antibodies circulating in their blood that target their own body tissues. See the entire definition of Autoimmune disease

A disease in which autoantibodies or lymphocytes attack other molecules, cells, or tissues within the body; the body launches an immune response against its own tissue. Psoriasis is widely believed to be an autoimmune disease, as is psoriatic arthritis.

disease that causes the body's own defence system to react against its own cells and tissue.

a disease in which the body's defense system malfunctions and attacks a part of the body itself rather than foreign matter.

any of a large group of diseases characterized by abnormal functioning of the immune system that causes it to produce antibodies against your own tissues.

Disease caused by reaction of the body's immune system against a component of the body.

a disease produced --the body's normal tolerance of its own antigenic markers on cells disappears. Autoantibodies produced by B lymphocytes and attack cells, whose surface contains a "self' antigen or autoantigen, causing destruction of tissue. Includes diseases such as: rheumatoid arthritis, multiple sclerosis, and Graves' disease.

A disease that triggers the immune system to react against the body’s own tissues and to produce abnormal antibodies that attack these tissues.

A disease caused by the immune system attacking the cells of one's own body rather than attacking foreign cells such as germs.

A disease that results when the immune system mistakenly attacks the body's own tissues. Rheumatoid arthritis and systemic lupus erythematosus are autoimmune diseases. (Read about " Arthritis and Rheumatic Diseases")

One in which the immune system destroys or attacks the patient's own body tissue.

A condition in which the body tissues are attacked by its own immune system. Related links

a disease whereby an individual's immune system mounts an attack on a portion of its own tissues. Tissues undergoing such an attack can be destroyed in the process. Rheumatoid arthritis is an example of an autoimmune disease.

A disease in which the body’s immune system attacks the body producing a disease state. Examples include psoriasis, rheumatoid arthritis, diabetes, Systemic Lupus Erythematosus (Lupus), Crohn’s disease and others.

a disease whereby the body's immune system mistakes some of the body's own cells (antigens) for pathogenic cells and tries to kill them off. These diseases tend to be chronic because the immune system can not usually get rid of the 'offending' antigen completely. The exact cause is unknown. Bacteria - are a group of primitive micro-organisms. Some like to live in humans and other animals but don't always cause disease. For example, there are millions of "friendly" bacteria that live in our intestines and take up all the room and food so that disease causing bacteria can't infect us. Whilst our immune systems will tolerate these friendly bacteria, the antigens on disease-causing bacteria are recognised as dangerous and an immune response is activated.

a disease caused by the immune system "rejecting" self tissues

A disease which arises from and is directed against an individual's own tissue (a problem with transplants).

A disease in which the body's immune system turns against and damages the body's own tissues.

a disease that results when the immune system mistakenly attacks the body's own tissues. Rheumatoid arthritis and systemic lupus erythematosus are autoimmune diseases ("auto" means self).

When your bodyâ€(tm)s own immune response – its own antibodies – destroy its own body tissues.

A condition caused when an individualâ€(tm)s immune system reacts against his or her own organs and tissues (see Arthritis).

is a type of illness that occurs when the body tissues are attacked by its own immune system. People suffering from autoimmune diseases tend to have unusual antibodies circulating in their blood that target their own body tissues. Autoimmune diseases are more common in women than in men. Examples of autoimmune diseases include systemic lupus erythematosus (SLE or lupus), rheumatoid arthritis, multiple sclerosis, juvenile (type 1) diabetes, Addison disease, vitiligo, pernicious anemia, glomerulonephritis, and pulmonary fibrosis.

Any condition in which the immune system attacks and destroys its own body's healthy tissues.

Although the main purpose of the body's immune system is to fight infection, sometimes the immune system turns on the body itself, damaging parts of the body. The diseases produced when this occurs are called autoimmune diseases. Currently available evidence suggests that multiple sclerosis may be an autoimmune disease.

A disorder in which the immune system mistakenly attacks and destroys body tissue that it believes to be foreign. In type 1 diabetes, an autoimmune disease, the immune system attacks and destroys the insulin-producing beta cells.

A disorder caused when the body fails to recognize itself and mounts an immune attack (usually reserved for invading bacteria or a viral infection) producing antibodies against its own tissue. In MG, the acetylcholine receptors are the victims of this misdirected immune attack.

A disease, such as rheumatoid arthritis, win which the body attacks its own tissues.

This is a malfunction of the body's immune system. Normally, the immune system works to defend the body and eliminate infections by destroying bacteria, viruses, and other invading microbes. When the immune system is not working properly, it may mistakenly attack the normal cells, tissues, and organs of a person's own body. Some examples of autoimmune diseases are lupus, Hashimoto's thyroiditis, Graves disease, and Guillain-Barré syndrome.

A disease that results from the body's reaction to itself, instead of to infection. Examples include lupus, multiple sclerosis, and rheumatoid arthritis.

immune response directed against tissues within one's own body

A condition in which antibodies form against one's own cells.

A disease that occurs when the immune system turns against parts of the body it is designed to protect.

A disease in which the body's immune system mistakenly fights and rejects the body's own normal tissue. For example, Lupus is an autoimmune disease.

1. Disorder of the body's immune system in which the immune system mistakenly attacks and destroys body tissue that it believes to be foreign. Insulin-dependent diabetes is an autoimmune disease because the immune system attacks and destroys the insulin-producing beta cells. 2. Illnesses which occur when the body tissues are attacked by its own immune system. The immune system is a complex organization within the body that is designed normally to "seek and destroy" invaders of the body, particularly infections. Patients with these diseases have unusual antibodies in their blood that target their own body tissues.
