Compounds for diagnosis and/or therapy of tumours

Abstract

Compounds are provided for use in the diagnosis and/or therapy of tumors and/or as immunosuppressive agent. The compounds are antibodies which bind to IL-4 receptors and IL-4 receptor-binding fragments thereof. A preferred compound is monoclonal antibody MR-6 produced by the hybridoma deposited at the European Collection of Animal Cell Cultures with the accession number 88033002. The invention also extends to the use of the compounds for in vitro removal of graft-versus-host reactive T-lymphocytes prior to bone marrow transplantation and to a novel protein of molecular weight 200,000 daltons functioning as a receptor for IL-4.
