  • Publication number: 20230303680
    Abstract: The invention provides a human IL-2 (hlL-2)-specific monoclonal antibody, wherein a complex of hlL-2 and the monoclonal induces IL-2 signalling preferentially via CD25 and the trimeric IL-2R. The invention further provides a pharmaceutical composition comprising hlL-2 and said hlL-2-mAb for use treating inflammatory disease.
