FIELD: chemistry. n SUBSTANCE: invention relates to biochemistry, particularly to recombinant fused protein dimers intended to inhibit or suppress immune response in a mammal, which bind human CD80 or human CD86 or the extracellular domain of any thereof, and has higher capacity for suppressing immune response than a dimer of the fused protein LEA29Y-Ig. Also disclosed are nucleic acids which code said dimers, expression vectors containing said nucleic acids, as well as recombinant host cells containing said nucleic acids and/or said vectors. Disclosed are pharmaceutical compositions for inhibiting or suppressing immune response in a mammal, which contain said fused protein dimers, as well as use of said dimers to produce drugs for inhibiting or suppressing immune response in a mammal, treating diseases or disorders of the immune system or treating organ or tissue transplant rejection in a mammal. Methods of producing said fused protein dimers are also disclosed. n EFFECT: invention provides effective inhibition or suppression of immune response in a mammal. n 9 cl, 15 dwg, 11 tbl, 12 ex |
