monômero de anticorpo de domínio, ligando, ácidos nucleicos isolado e recombinante, vetor, célula hospedeira, método para produzir um monômero de dab de ligando, composição farmacêutica, dispositivo de liberação de medicamento, uso de um monômero de anticorpo de domínio, e, método para tratar uma doença inflamatória, artrite ou doença respiratória

The invention relates to dAb monomers that bind IL-1R1 and inhibit binding of IL-1 (e.g., IL-1alpha and/or IL-1beta) to the receptor but do not inhibit binding of IL-1ra to IL-1R1, and to ligands comprising such dAb monomers. The invention relates to protease resistand dAb monomers, and to ligands comprising protease resistant dAb monomers. The invention also relates to nucleic acids including vectors that encode the dAb monomers and ligand, to host cells that comprise the nucleic acids and to method for producing a dAb monomer or ligand. The invention also relates to pharmaceutical compositions that comprise the dAb monomers or ligands, and to therapeutic methods that comprise administering a dAb monomer of ligand.
