Autoantibody

An autoantibody is an antibody that is formed in the human body and is directed against its own cells and tissues. The production of autoantibodies occurs in autoimmune diseases when the immune system mistakenly recognizes normal body cells as foreign and launches an immune response against them.

Autoantibodies can react with various self-antigens - proteins, nucleic acids, hormones and other molecules. They bind to these molecules, which leads to the destruction of tissues and disruption of their normal functioning.

Autoimmune diseases in which autoantibodies are formed include: rheumatoid arthritis, systemic lupus erythematosus, type 1 diabetes mellitus, multiple sclerosis, Graves-Basedow disease and others. Diagnosis of these diseases is based on the detection of specific autoantibodies in the blood.

Thus, autoantibodies play a key role in the development of autoimmune pathology. Their detection makes it possible to confirm the autoimmune nature of the disease and prescribe adequate treatment aimed at suppressing the unwanted immune response.

Autoantibodies are antibodies that are formed in the human body against its own structures, which can lead to the development of autoimmune diseases. These antibodies can be directed to various organs and tissues, such as skin, joints, heart, kidneys and others.

Autoantibodies can be found in people suffering from various autoimmune disorders such as rheumatoid arthritis, systemic lupus erythematosus, type 1 diabetes, Hashimoto's thyroiditis and others. They may also be present in healthy people, but in smaller quantities.

The mechanism of autoantibody formation is not fully understood, but it is believed that they can be caused by various factors, such as genetic predisposition, infections, trauma, stress and other factors.

Symptoms of autoimmune diseases caused by autoantibodies may include joint pain, fatigue, fever, weight loss, skin problems and other symptoms. Diagnosis of autoimmune diseases may include blood testing for the presence of autoantibodies and other research methods. Treatment for autoimmune diseases usually includes medications, lifestyle changes, and physical therapy.

Overall, autoantibodies are an important topic of study as they may indicate the development of autoimmune diseases and help in the development of new treatments.

Autoantibodies (AA) are a class of antibodies that are formed in the body against a person's own protein structures. This occurs in an autoimmune disease in response to malfunctioning immune responses. Many of them are also found in healthy populations. Protection against bacteria is also useful in our body.
