Melanin inspired microcapsules delivering immune metabolites for hepatic fibrosis management.

ABSTRACT: Patients with hepatic fibrosis (HF) have a high risk of developing liver cirrhosis and hepatocellular carcinoma, and there is an urgent need for preventive strategies to block this process. Previous studies have found that disordered inflammation and oxidative damage play important roles in HF progression, suggesting two attractive therapeutic targets. Herein, a new kind of bioinspired microcapsules with a core-shell structure is generated using microfluidics. Polydopamine nanoparticles (PDANPs), a synthetic analogue of natural melanin, are embedded in the polymer shell to provide antioxidative properties for these microcapsules. The aqueous core is used to encapsulate ketone body β-hydroxybutyrate (BHB), an energy metabolite recently known to have regulating effects of cellular signals in
