The epithelial mucosa is a key biological barrier faced by gastrointestinal, intraoral, intranasal, ocular, and vaginal drug delivery. Ligand-modified nanoparticles demonstrate excellent ability on this process, but their efficacy diminished the formation of protein coronas (PCs) when they interact with matrices. PCs are broadly implicated in affecting fate NPs vivo vitro, yet few studies have investigated formed during interactions mucosa, especially mucus. In study, we constructed transferrin modified (Tf-NPs) as model explored mechanisms effects that had subsequent impact transcellular transport Tf-NPs. mucus-secreting cells, Tf-NPs adsorbed more proteins from mucus layers, which masked, displaced, dampened active targeting Tf-NPs, thereby weakening endocytosis efficiencies. mucus-free intracellular trafficking, enhanced transcytosis related functions.
