Autoimmune disease is a condition arising from an abnormal immune response to a normal body part. There are at least 80 types of autoimmune diseases. Nearly any body part can be involved. About 24 million (7%) people in the United States are affected by an autoimmune disease. The cause is generally unknown.
Treatments usually depend on the type and severity of the condition. Traditional treatments include Nonsteroidal anti-inflammatory drugs (NSAIDs) and immunosuppressants. While treatment usually improves symptoms they do not typically cure the disease.
Recently increasing evidence indicates that NAD+ may play an active role in protecting against/treatment of autoimmune disease.
