Abstract An oral colon-targeted drug delivery system holds great potential in preventing systemic toxicity and preserving the therapeutic benefits of ulcerative colitis (UC) treatment. In this study, we developed a negatively charged PLGA-PEG nanoparticle system for encapsulating naringin (Nar). Additionally, chitosan and mannose were coated on the surface of these nanoparticles to enhance their mucosal adsorption and macrophage targeting abilities. The resulting nanoparticles, termed MC@Nar-NPs, exhibited excellent resistance against decomposition in the strong acidic gastrointestinal environment and specifically accumulated at inflammatory sites. Upon payload release, MC@Nar-NPs demonstrated remarkable efficacy in alleviating colon inflammation as evidenced by reduced levels of pro-inflammatory cytokines in both blood and colon tissues, as well as the scavenging of reactive oxygen species (ROS) in the colon. This oral nanoparticle delivery system represents a novel approach to treating UC by utilizing Chinese herbal ingredient-based oral delivery and provides a theoretical foundation for local and precise intervention in specific UC treatment. |
