Good Autoantibodies (IMAGE) Istituto di Ricerca in Biomedicina Caption During infection, chemokines attract cells of the immune system to the lungs where they neutralize the virus and destroy infected cells. Top: Excessive activation of the immune system (dark red) can be a double-edged sword, leading to major damage associated with severe Covid. Bottom: the presence of 'good autoantibodies' that absorb chemokines reduces excessive immune activation leading to a milder course of the disease.
