Normally autoantibodies are routinely eliminated by the immune system’s self-regulatory … WebAutoantigens are the result of mutation, neoantigen formation, or exposure of previously hidden self-antigens. Genes producing self-proteins can mutate and create a new immunogenic protein called neoantigen. Viral infections and drugs can create neoantigens that stimulate an immune response.
An autoantibody is an antibody (a type of protein) produced by the immune system that is directed against one or more of the individual's own proteins. Many autoimmune diseases (notably lupus erythematosus) are associated with such antibodies.
