Autoantibodies is antibodies attack one’s own cells. The part of the cells that are attacked in pemphigus are proteins called desmogleins. Desmogleins form the glue that attaches skin cells together, keeping the skin intact. When autoantibodies attack desmogleins, the cells become separated from each other. when skin becomes unglued.
