Background	Interleukin-1 (IL-1) defines two polypeptides, IL-1α and IL-1β, that possess a wide spectrum of biological effects. Two natural antagonists of IL-1 action have been characterized: the IL-1 receptor antagonist (IL-1Ra) and a soluble form of the type II IL-1 receptor. Neutralizing autoantibodies to IL-1α have also been detected in sera of healthy individuals and patients with autoimmune or inflammatory diseases. By combining CD40-activation and Epstein-Barr virusimmortalization of B lymphocytes from individuals with circulating anti-IL-1α, a natural anti-IL- 1α monoclonal autoantibody was developed that bound specifically to human IL-1α, but not to IL- 1β and IL-1Ra, with a high affinity (Kd = 1.2 × 10−10 M). HuMAb X3 inhibited IL-1α binding to IL-1 receptors and neutralized biological activities of both recombinant and natural forms of IL-1α. This high affinity neutralizing anti-IL-1α human autoantibody can function as a third type of IL-1 antagonist.
