FIELD: medicine, pharmaceutics.SUBSTANCE: present invention refers to immunology. What is presented is a polypeptide containing two binding fragments presented by antibodies; the first of them binds to CD3e(epsilon) chain epitope of a human or a primate, other than a chimpanzee, particularly Callithrix jacchus, Saguinus oedipus and Saimiri sciureus; the second one - to EGFR, Her2/neu or IgE of a human or a primate, other than a chimpanzee, with the above CD3e epitope containing the amino acid sequence Gln-Asp-Gly-Asn-Glu. There are also disclosed a coding sequence of the nucleic acid, a vector, a host cell and a method for preparing the above peptide, as well as a pharmaceutical composition and using the polypeptide in preventing, treating or relieving a proliferative disease, a malignant disease or an immunological disorder.EFFECT: invention provides the clinical improvement of T-cell redistribution and the enhanced safety profile.17 cl, 8 tbl, 26 dwg, 26 ex |
