This is a preclinical proof-of-concept study in mice demonstrating that a novel engineered oral nanomedicine (GLONs) can eradicate H. pylori and reverse precancerous intestinal metaplasia more effectively than abbreviated triple-therapy in a 7-day regimen. The mechanism involves Sirtuin 1 restoration and activation of autophagy and antimicrobial responses. No human efficacy, safety, or pharmacokinetic data are presented; the work represents early-stage mechanistic discovery requiring validation in human trials.
Preclinical pilot study with proteomic screening and mouse models. Clinical gastric mucosal samples from patients (proteomic screening; sample size not stated); mouse models of H. pylori infection and intestinal metaplasia.. Intervention: Gastric epithelial cells-localizable oral nanomedicines (GLONs): resveratrol, lactoferrin, and disulfide modified-fucoidan co-assembled nanoparticles coated with engineered mucin-overexpressing gastric epithelial cell membranes, administer…. Compared with: Abbreviated triple-therapy, regimen duration not specified..
GLONs produced greater reductions in gastric H. pylori burden in mouse models compared to abbreviated triple-therapy under 7-day regimen GLONs produced more pronounced improvements in intestinal metaplasia-related phenotypes than abbreviated triple-therapy Pilot proteomic screening suggested progressive decline in Sirtuin 1 abundance along H. pylori-associated pathological cascade

The ability to treat Helicobacter pylori (H. pylori) infection and eliminate its associated gastric cancer risk is highly desirable but has proven to be extremely difficult. In this study, pilot proteomic screening of clinical gastric mucosal samples suggested a progressive decline in Sirtuin 1 abundance along the H. pylori-associated pathological cascade. Based on these findings, gastric epithelial cells-localizable oral nanomedicines (GLONs) are developed, whereby H. pylori eradication and reversal of precancerous intestinal metaplasia (IM) are simultaneously achieved via Sirtuin 1 restoration. GLONs are constructed by coating resveratrol, lactoferrin, and disulfide modified-fucoidan (DFu) co-assembled nanoparticles (RLF) with engineered mucin-overexpressing gastric epithelial cell membranes. The shell of GLONs resists gastric acid, enhances mucus penetration and epithelial cells uptake. After internalization, DFu undergoes oxidative destabilization in the H2O2-enriched infectious microenvironment induced by H. pylori, thereby triggering RLF core dissociation and subsequent component release. The resveratrol restored H. pylori infection-induced impairment of Sirtuin 1, thereby activating autophagy. Meanwhile, lactoferrin promoted antimicrobial peptide production and synergized with fucoidan-mediated enhancement of antigen presentation, ultimately enabling the clearance of both intracellular and extracellular H. pylori. In metaplastic gastric cells, Sirtuin 1 repairs damaged DNA, and inhibits malignant proliferation. In mouse models, under the tested 7-day regimen, GLONs produced greater reductions in gastric H. pylori burden and more pronounced improvements in IM-related phenotypes than the abbreviated triple-therapy. GLONs represent an innovative and highly efficient therapeutic platform for H. pylori infection and its complications.
