Understanding Autoimmune Diseases: Causes and Mechanisms

TLDRAutoimmune diseases occur when the body's immune system mistakenly attacks its own cells. There are more than 100 autoimmune diseases, such as Type 1 Diabetes, Multiple Sclerosis, Lupus, and Rheumatoid Arthritis. The risk of developing an autoimmune disease depends on genetics and environmental exposures. Symptoms vary depending on the type of autoimmune disease. Diagnosing autoimmune diseases involves evaluating symptoms, blood tests, and autoantibodies. Autoimmunity can result from autoimmune antibodies and autoimmune T-cells. Tolerance checkpoints can fail, leading to autoimmunity. Autoimmune diseases are likely caused by molecular mimicry, bystander activation, and epitope spreading. Viral persistence may also contribute to the development of autoimmune diseases. Treatment focuses on symptom management and reducing inflammation.
