Figure Lengend Snippet: ( A ) Synthetic scheme of siRNA-GBSA(CHI/TA) n NPs. ( B ) siRNA-GBSA(CHI/TA) 5 NPs were orally administered by gavage and passed smoothly through the extreme stomach environment under the protection of (CHI/TA) 5 armor. The armor slowly degraded at the intestinal site, enriching the inflamed colon through electrostatic adsorption and polyphenol adhesion. ( C ) The microenvironment of the inflamed colon site was regulated by relieving the inflammatory responses and alleviating the imbalance of intestinal flora by siRNA-GBSA(CHI/TA) 5 NPs. Moreover, inflammation in the brains of IBD mice was also alleviated via the gut-brain axis and accompanied by decreased activation of astrocytes, microglia, and neuroinflammatory cells in the brain. Consequently, the relief of brain inflammation improved cognitive performance.
