Abstract

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial lung disease characterized by sustained fibrotic lesions. Orally administered drugs usually fail to efficiently penetrate the interstitial tissue and reach the lesions, resulting in low treatment efficiency. Luteolin (Lut) is a natural flavonoid, active metabolites of which possess antioxidant, anti-inflammatory, anti-fibrotic, and anti-apoptotic properties. In this study, a nano-formulation is developed by loading Lut into hyaluronidase nanoparticles (Lut@HAase). These Lut@HAase nanoparticles (NPs) exhibit small size and good stability, suitable for noninvasive inhalation and accumulation in the lungs, and hyaluronidase at the site of lesions can degrade hyaluronic acid in the interstitial tissue, enabling efficient penetration of Lut. Lut's therapeutic effect, when administered via NPs, is studied both in vitro (using MRC5 cells) and in vivo (using IPF mice models), and its anti-fibrotic properties are found to inhibit inflammation and eliminate reactive oxygen species. Conclusively, this study demonstrates that Lut@HAase can improve lung function and enhance survival rates while reducing lung damage with few abnormalities during IPF treatment.
