제목 Self-assembled Flt1 peptide-hyaluronic acid conjugate nanoparticles for the treatment of asthma
초록 Dexamethasone (Dexa) loaded Flt1 peptide – hyaluronic acid conjugate (Flt1 – HA) nanoparticles were successfully prepared for the treatment of neutrophilic pulmonary inflammation. In vitro bioimaging showed efficient internalization of Flt1 – HA nanoparticles into lung epithelial cells. Also, ex vivo imaging for the biodistribution in ICR mice revealed long-term retention of Flt1 – HA nanoparticles in deep lung. On the basis of bioimaging results for pulmonary drug delivery applications, we prepared Dexa-loaded Flt1 – HA nanoparticles. TEM and DLS confirmed the formation of nanoparticles, which reduced cytokine levels of lipopolysaccharide (LPS)-stimulated cells more efficiently than free Dexa. Furthermore, according to the bronchoalveolar lavage (BAL) cellularity and histological analysis, Dexa loaded Flt1 – HA nanoparticles showed remarkable therapeutic effects in both eosinophilic and neutrophilic asthma model mice.
