Abstract

The present invention provides antibodies, or antigen-binding portions thereof, which specifically bind to IL-2 and reduce the affinity of IL-2 binding to IL-2Rα and IL-2Rβ. The invention further provides a method of obtaining such antibodies and nucleic acids encoding the same. The invention further relates to compositions and therapeutic methods for use of these antibodies for the treatment and/or prevention of autoimmune diseases, disorders or conditions and for immunosuppression, including, but not limited to, administering a complex comprising the antibody and IL-2.
