Although that marker, called IL21, had not previously been associated with
autoimmune diseases, the gene that produces it sits right in the stretch of DNA known to make these mice vulnerable to diabetes, suggesting that IL21 might make a drug

by successfully treating an otherwise fatal
autoimmune disease in a mouse model, without apparent off -

Scientists were able to selectively
target the cells that cause
autoimmune disease by dampening down their aggression against the body's own tissues while converting them into cells capable of protecting against
disease.
Patients with PNDs carry antibodies that specifically
target these proteins, but identifying the
target antigens — intracellular proteins — challenged the dogma that the antibodies mediate
disease by causing an
autoimmune attack on brain tissue.
These syndromes include conditions in which autoimmunity is clearly implicated as causal, in light of identification of autoantibodies to relevant autoantigens;
diseases suspected to be
autoimmune because of the presence of autoantibodies, although the autoreactive response has not been proven to be pathogenic and could be a consequence or marker of tissue damage; and other
diseases often considered to be «
autoimmune,» such as psoriasis or inflammatory bowel
disease, characterized
by organ -
targeted inflammation but without evidence of a stimulating autoantigen.
