| Research Abstract |
We synthesized novel peptides which could inhibit the binding of mouse PDGF-BB to PDGFRbeta. From these peptides, we identified the peptide No.3 showing the strong inhibitory effects of the proliferation of lung fibroblasts in vitro. The FAM-labelled peptide No. 3 strongly bound to lung fibroblasts under a fluorescence microscopy. The administration of peptide No.3 as an inhaled therapy reduced bleomycin-induced lung fibrosis in mice. These results suggest that the peptide might be a novel and promising therapeutic agent for pulmonary fibrosis.
