autoimmunity
A condition in which the body's immune system mistakenly attacks its own cells. This concept is discussed in relation to the folate receptor auto-antibody theory as a potential cause of some cases of autism.

Summary
Autoimmunity is a fundamental immunological phenomenon where an organism's immune system mistakenly targets its own healthy cells, tissues, and other normal bodily components. While this self-reactivity, characterized by the presence of autoantibodies or T cells, is a natural occurrence even in healthy individuals, it can lead to severe autoimmune diseases if it results in tissue damage. Prominent examples of such diseases include celiac disease, type 1 diabetes mellitus, systemic lupus erythematosus, Sjögren syndrome, Hashimoto's thyroiditis, Graves' disease, rheumatoid arthritis, and multiple sclerosis, which are often managed with steroid treatments. The concept of autoimmunity, specifically involving the folate receptor, has also been a subject of scientific discussion regarding a potential link between autism and Tylenol (acetaminophen) use during pregnancy, as highlighted in a podcast discussing a paper by Andrea Bakarelli.

In immunology, autoimmunity is the system of immune responses of an organism against its own healthy cells, tissues and other normal body constituents. Any disease resulting from this type of immune response is termed an "autoimmune disease". Prominent examples include celiac disease, diabetes mellitus type 1, Henoch–Schönlein purpura, systemic lupus erythematosus, Sjögren syndrome, eosinophilic granulomatosis with polyangiitis, Hashimoto's thyroiditis, Graves' disease, idiopathic thrombocytopenic purpura, Addison's disease, rheumatoid arthritis, ankylosing spondylitis, polymyositis, dermatomyositis, and multiple sclerosis. Autoimmune diseases are very often treated with steroids. Autoimmunity means presence of antibodies or T cells that react with self-protein and is present in all individuals, even in normal health state. It causes autoimmune diseases if self-reactivity can lead to tissue damage.

There’s no cure for autoimmune diseases, but your healthcare provider will help you find treatments that manage the symptoms you experience. ### What are autoimmune disease symptoms? We know your immune system mistakenly damaging your body instead of protecting it causes the symptoms of an autoimmune disease you experience. Some common treatments to manage autoimmune disease symptoms include: Conditions like multiple sclerosis and myositis are more likely to be fatal than many autoimmune diseases, but that doesn’t mean they always are. If you’ve already been diagnosed with an autoimmune disease, tell your provider if it feels like your treatments aren’t working as well as they used to or if the symptoms are recurring more often.
- Definition of Autoimmunity & Autoimmune Disease
Autoimmune diseases develop when the auto-reactive B lymphocytes (autoantibodies) and T lymphocytes described above cause a pathological and/or functional damage to the organ/tissue containing the target autoantigen(s). B cells also secrete antibodies that when directed against self components are called autoantibodies (as found in patients with autoimmune diseases). A normal component of the patient, such as a protein or a protein-nucleic acid complex, that becomes recognized by the patient's own antibodies and/or T lymphocytes during an autoimmune disease. The type of antibodies that recognize antigens of the patient, always present in autoimmune diseases and sometimes causing them. An autoimmune disease predominantly targeting the thyroid gland, and mediated by autoantibodies that bind to and stimulate a receptor expressed on thyroid cells called TSH receptor.

It’s clear that there are factors, beyond a person’s genetic makeup, that contribute to a person’s chance of developing an autoimmune disease. Some infections may increase the chance of developing an autoimmune disease. Medications have also been implicated in the development of autoimmune disease. Again, it is important to understand that while genetics, infections, smoking, and certain medications are associated with risk, none have been definitively shown to cause autoimmune disease. The American College of Rheumatology encourages you to meet with your care team regularly to ensure you manage your disease and continue to live a healthy life. At NYU, she saw a diverse group of patients with complicated autoimmune diseases and contributed to the education of fellows and faculty.
