Increasing evidence indicates that a healthy diet plays a protective role against ischemic stroke injury. As an antioxidant food， grape powder has been shown to have a neuroprotective function after ischemic injury. In the current research， we aimed to determine whether regular grape powder (GP) feeding before brain damage plays a protective role against ischemic damage and its potential mechanism. Mice had grape powder in drinking water for 4 weeks. Then， fecal samples were collected for 16S RNA analysis and metabolite profiling. Ischemic stroke was triggered using GP prefeed mice by MCAo (middle cerebral artery occlusion) to compare the stroke-induced infarction size to the drinking water (DW) group. The data showed that 4 weeks of GP pretreatment significantly decreased the ischemic infarct size. Meanwhile， GP treatment altered the gut microbiota by enriching the population of Lachnospiraceae and enhancing a gut metabolite called fiestin， which belongs to the flavonoid group. Mechanistically， we demonstrated that fiestin could inhibit LPS-induced proinflammatory macrophage polarization in vitro. We also showed that regular grape power feed could decrease stroke-induced neuroinflammation in vivo. In conclusion， our study demonstrated that 4 weeks of GP feeding attenuates experimental ischemic stroke via the gut-brain-immune axis.
