Fusion protein Slit2D2(C386S)-HSA and use thereof in treatment of fibrotic diseases

摘要

The present invention relates to the field of biomedical technology, in particular to a fusion protein Slit2D2(C386S)-HSA and use thereof in the treatment and/or prevention of fibrotic diseases. In the fusion protein, the amino acid residue is mutated on the basis of the Slit2D2 domain, which improves the stability of the fusion protein compared with the native protein. The above fusion protein is obtained by fusing Slit2D2(C386S) with HSA protein, which prolongs the metabolism time of the drug while improving the stability of the drug. The fusion protein provided by the present invention is more effective than the positive control drug in the prevention and treatment of fibrotic diseases, particularly pulmonary fibrosis, and shows good drug-forming properties.
