POLIPEPTIDO QUIMERICO FIBRINA-FILAGRINA CITRUINADO CAPAZ DE DETECTAR LOS ANTICUERPOS GENERADOS EN LA ARTRITIS REUMATOIDE

摘要

The present invention concerns a chimeric polypeptide, capable of detecting the antibodies generated in rheumatoid arthritis, comprising at least two citrulinated peptide subunits: (i) one derived from the ± or ² chain of the fibrin and (ii) a second derived from the filaggrin. In addition, the invention comprises an antigenic composition, a method and a kit for the diagnosis of rheumatoid arthritis, from the detection of the autoantibodies generated during the course of said disease.
